SCOTSBORO, ALABAMA- The clock is ticking as far as the future of the BB Comer Bridge is concerned. The replacement span is close to completion, and there are still some issues to settle as far as the future of the 1930 steel cantilever truss bridge is concerned. Apart from the ownership and liability, some further studies on the impact of keeping the historic bridge- among them economic, are being considered. As you can see in the most recent press release by the Comer Bridge Foundation, a grant is being sought so that an independent entity is hired to conduct an impartial economic survey, which will in turn persuade county officials to hand over ownership to the CBF once the new bridge is open to traffic. The date of the completion as well as the eventual demolition has not yet been set, however parties will have to act quickly but thoroughly to ensure that once the new bridge is open, the decision on the future of the old bridge will be made to benefit all the parties involved. More information on the progress of the bridge is in the press release below:
SCOTTSBORO, AL, January 30, 2015 — After the January 26, 2015, meeting of the Scottsboro City Council, the Comer Bridge Foundation (CBF) is now identifying and hiring an independent entity to prepare an economic impact study. The B.B. Comer Bridge crosses the Tennessee River near Scottsboro, Alabama. An application for grant funding to assist with procuring the study will be submitted to the National Trust for Historic Preservation to comply with the Trust’s deadline (February 2, 2015).
“We have determined that such a study is essential for CBF to show local citizens and governmental bodies how much the bridge can bring to the area, which in turn will help CBF gain eventual ownership of the bridge and prevent the bridge’s demolition. The timeline for demolition is not as tight as we anticipated, and we have time to explore how to lessen risks while growing the rewards of keeping the bridge intact,” explained CBF President Charles Holderfield.
“The study will solidify CBF’s commitment to saving, preserving and repurposing the bridge at an upcoming meeting of the Jackson County Commission,” said Holderfield.
In March 2014, CBF entered into a collaborative agreement with The N. Skunk River Greenbelt Association (NSRGA), another bridge-preservation group. Local attorneys Bill Tally and Justin Lackey represent CBF and NSRGA, respectively.
“The study will provide real numbers that support our plans to provide jobs, training and education in areas from hospitality, event management, security and maintenance,” shared Julie Bowers, executive director of Workin’ Bridges, the consulting arm of NSRGA. “The bridge can become a place to go for wellness and serenity, and a place where wildlife and human life are celebrated. Food, fun, music and historic preservation go hand-in-hand.”
The board of directors for CBF and NSRGA submitted a formal purchase plan to the Alabama Department of Transportation (ALDOT), which currently owns the bridge. In September 2014, however, ALDOT informed the two organizations that the bridge could be sold only to a governmental entity. With support from the National Trust for Historic Preservation and the Land Trust of North Alabama, Justin Lackey went before the Scottsboro City Council in mid-January 2015 to request that a tourism development authority be formed by the City to take ownership of the bridge. In addition to owning, leasing and developing land, improving and managing real estate and owning equipment, the authority could also employ personnel, execute documents, and accept and receive gifts from the public or private funds. It would also be able to apply for and receive federal grants.
The City Council members asked for additional time to study the request prior to its next regular meeting on January 26, at which time Lackey requested that the Council vote on the creation of the tourism development authority. The City deferred voting on the authority, with the majority of the Council members agreeing that the City could approve such an authority only in partnership with the County Commission. CBF will provide the economic impact study to the County Commission for review prior to formally requesting that the Commission consider partnering with the City Council to create the tourism development authority.
Comer Bridge, completed in 1930, is the last of the 15 memorial toll bridges enacted by legislation in 1927 that were built by the Kansas City Bridge Company but contracted through the Alabama State Bridge Corporation. Selected for the Alabama Register of Landmarks and Heritage in October 2013, the historic bridge will now be submitted for national recognition by the Keeper of the National Register of Historic Places (NRHP).
Certificate from the Alabama Register of Landmarks and Heritage.

Bridge collapses in Ohio- one dead, Bridge in Kansas City demolished, Two Arkansas bridges coming out, also one in Missouri.
Could we see a repeat of 2013? Judging by the number of bridges being demolished or being scheduled to be demolished, it seems that 2015 is reverting back to the days where the draconian mentality of replacing instead of fixing at the expense of tax payers is the norm. Yet, despite the massacre of over a dozen bridges at the beginning of 2013 and more throughout the year, the number of bridges scheduled to come out are much fewer. But some of the bridges that are targeted for demolition are the same ones that are being fought by preservationists to save them because of their historic value. With the collapse of an old Interstate bridge in Ohio last night though, that might provide a knee-jerk reaction among politicians and engineers to override the protests, as seen with the Linz Railroad Bridge in Austria. With more on that, here are the headlines:
Interstate Bridge in Cincinnati (Ohio) collapses- one dead.
CINCINNATI- Spanning Hopple Street carrying northbound Interstate 75, the 1960s style bridge was scheduled to be demolished after the new bridge opened to traffic weeks ago, and workers were already prepping the old structure to be removed from service. Little did they realized is that the bridge itself found its way to the dumpster earlier than expected. The structure collapsed at 10:30pm last night, as the main span dropped onto the street below, crushing everything like pancakes. A construction worker on the bridge was killed in the collapse. A truck driver going towards the bridge on Hopple Street slammed on the brakes as it collapsed, missing him by inches. The front of the semi truck sustained extensive damage but the driver survived with only minor injuries. According to Jeffrey Blackwell of the Cincinnati Police Department, it was a matter of just seconds, “and his fate would have been different.” The collapse the bridge triggered the shutdown of the entire freeway, which will take days while crews clean-up the disaster. While there were no reports of any structural shortcomings with the bridge, investigations are being undertaken to determine how the bridge collapsed in the first place. More on the article and photos of the collapse can be found via link here.
War Eagle Bridge in Danger!
BENTON COUNTY, ARKANSAS- Spanning War Eagle Creek in Benton County, Arkansas, this 1907 structure built by Illinois Steel, features a Parker through truss main span, three Waddel A-frame pony approaches made from scrap metal and another steel beam approach, making the bridge 183 feet long. The bridge was rehabilitated in 2010 at a cost of $600,000. Now the county is looking into options with the bridge, claiming that the bridge has problems worth $1.8 million. The options are to either make the repairs and leave the bridge open to traffic or replace the bridge on a new alignment, but keep the truss span in tact for pedestrian use. Both the bridge and its adjacent mill are considered historic landmarks by the National Register, but the bridge is only open for light vehicles only. How the future of this bridge will pan out remains to be seen. More information will follow on the Chronicles.
Eldorado Viaduct to be demolished
EL DORADO, ARKANSAS- There is something special about this bridge, spanning the railroad yard, spanning Hillsboro Street in El Dorado. The bridge was built in 1935 by Fred Luttjohann, a local engineer from Topeka, Kansas, and features an arch span, several T-beam spans, concrete ballustrades and a length of over 980 feet. A candidate for the National Register, this bridge is loved by many in the city. Yet the city council has voted to demolish the structure in favor of its replacement. Construction of the bridge is scheduled to take place in the summer. For more on the bridge and to view the pictures, please click here.
Fairfax Bridge demolished. Replacement bridge to come.
KANSAS CITY, MISSOURI- The Chronicles did a report last fall about the replacement of the Fairfax and Platte Purchase Bridges, spanning the Missouri River carrying US Hwy. 69 between Kansas and Missouri. The plan of merging two separate bridges into one large six-lane bridge by 2016 moved forward on Friday, when the 1935 truss bridge that had once carried the southbound portion of the highway imploded, sending the bridge’s spans into the water. Crews are in the process of removing the bridge remains from the river, cutting up the parts for scrap. Once completed, the new span will be constructed. The 1957 Platte Purchase Bridge will be demolished towards the beginning of next year, once the new southbound portion opens to traffic. Photos of the Fairfax Bridge demolition can be found here.

Picking up after leaving off Part I and the Author’s Choice Awards, we now move onto the next category of Bridge of the Year 2014. Several bridges nominated for this award because of their golden anniversary celebrated this past year became disappointments in the voting stats. Among them include the Tower Bridge (which turned 120 years old), the Forth Bridges (the suspension bridge turned 50 years old) and the Verrazano Narrows Bridge (which also turned 50). Yet none of the bridges stood a match against the winner of the Bridge of the Year Award- the Clifton Suspension Bridge over the River Avon in Bristol (the UK). It turned 150 years old in December and was the masterpiece of Ishambard Kingdom Brunel, who started this bridge (and his career) 30+ years earlier but died shortly before its completion. The bridge was mentioned even in the comment section when the ballot was finished and ready to vote in December. How did it do with second place Fehmarn Bridge in Germany and third place Firth of Forth Bridges? Look at the results below and see how much loving this chain suspension bridge spanning the high gorge got in the voting process:
1. Clifton Suspension Bridge in Bristol (UK): 67 votes (77%)
2. Fehmarn Bridge in Schleswig-Holstein (Germany): 8 votes (9%)
3. Firth of Forth Bridges in Scotland (UK): 5 votes (6%)

Best Example of a Restored Historic Bridge
In the category of Best Preservation example, there was a tight race among seven candidates battling for first and second places. However in the end, the Raven Rock Bridge in Huntderton County, New Jersey edged out the Red Bridge in Kansas City and the Freedom Prime Bridge in Indiana for the award. The bridge is one of the oldest in the state and was dismantled, sandblasted and repainted before being reassembled on a new concrete decking, all during the summer. The bridge looks just like new with the railing and decking being the only differences. Impressive enough for the award.
1. Raven Rock Bridge in New Jersey 5 (26%)
2. Red Bridge in Kansas City 4 (21%)
3. Freedom Prime Bridge in Indiana 3 (16%)

Best Kept Secret Individual Bridge
There were many really good bridge candidates in this category, regardless of whether it was in the US category or the International one. That was the primary reason for the rather low voter turnout because of the difficulty in deciding which ones deserved the awards. But in the end, the winner has to be determined, right? In the US category, we have the Independence Bowstring Arch Bridge, an abandoned King Bridge Company structure that has been abandoned for many years, but after winning the award, will most likely receive some attention regarding its reuse. It edged the Fort Morgan Rainbow Arch Bridge in Colorado by three votes and two bridges by four votes to win the title.
2. Ft. Morgan Rainbow Arch Bridge in Colorado 3 votes (21%)
T 3. Backyard Bridge in Packwood, Washington and Powwow Polygonal Truss Bridge in Amesbury, Massachusetts 2 votes (14%)
In the international subcategory, the results of this award were really tight, for each candidate received at least one vote. In the end, the Monks Bridge on the British Isle of Man won the award, followed by the Pont de Langlois in France and the Swimming Bridge in Wuppertal in the German state of North Rhine-Westphalia. Here are the results:
1. Monks Bridge on the Isle of Man in the UK- 4 votes (33%)
2. Pont de Langlois in France- 3 votes (25%)
3. Swimming Bridge in Wuppertal, Germany- 2 votes (17%)
In the all around category, the Monks Bridge finishes second behind the winner, the Independence Bowstring Arch Bridge, with the Pont de Langlois and Ft. Morgan Bridge finishing tied for third.
Ely Stret Bridge in Bertram
Best Kept Secret- City Tour Guide
The final category for the 2014 Ammann Awards is the City Tour Guide, awarded to the city and/or region with a high number of unique (historic) bridges worth visiting. Some of them have been mentioned in the Chronicles, yet other places to visit have been recommended by other websites, including some city websites. This year’s category featured a big upset in the USA category, as the historic bridges located in Bertram, Iowa (east of Cedar Rapids) upended Chicago and Pittsburgh for the title, whereas in the international category, Manchester (the UK) won the award, beating out Budapest and Sault Sainte Marie. Despite losing the Ely Street Bridge to flooding, Bertram has a wide selection of pre-1910 truss bridges located within a 10-mile radius, many of whom were built by local bridge contractors. Manchester has a wider selection of historic and modern bridges, whose designs are very appealing to the tourists. Both communities also share the title in the all around division as well, beating Chicago and third place Pittsburgh and Budapest.
1. Bertram, Iowa- 5 votes (33%)
2. Chicago- 4 votes (27%)
3. Pittsburgh- 3 votes (20%)
1. Manchester- 5 votes (42%)
2. Budapest- 3 votes (25%)
3. Sault Ste. Marie- 2 votes (17%)
T1. Bertram and Manchester
T3. Pittsburgh and Budapest
This sums up the 2014 Ammann Awards. The next time we start nominating and voting will be at the beginning of November. Please check the page on the Chronicles to find out when nominations are being accepted. In case you want to provide feedback on this voting process, please do so either in the comment section or by sending an e-mail directly to the author. Otherwise, get the cameras going and start finding some bridges worthy of this year’s results. Happy Bridgehunting and thanks for voting.

Before announcing the winners, the author would like to apologize for the delay of the announcement of the winners. The reasons were twofold: 1. While returning home to Germany after spending Christmas with family in the US, he and his family were sick thanks to the flu bug that swept through many parts of the country. Many voters also requested a grace period for that reason plus more time needed to decide on their candidates. 2. In many categories, we had at least three ties for first place resulting in the need to extend the deadline. For that, the extension served as a blessing for many.
Now for the moment of truth. For the first time, the Chronicles, in connection with Forum Communications in Fargo, used the Poll Daddy voting scheme, which turned out to be the most effective way to vote. Thanks to Kari Lucin for her help, it will be used again for the 2015 Awards, which will take place in December. More information under the Ammann Awards page.
The votes were tallied with the top three being announced here. However, a link with the complete list of candidates for the 2014 Awards can be found here.
Without further ado, the winners:
Located over the Raccoon River in Des Moines, the Green Bridge has been in the news for over a year because of a public-private project to remodel the structure. It has been mentioned for many awards and grants. This photo by Mitch Nicholson, who is the author of Abandoned Iowa (website can be found here), will add to the accolades the bridge has already received, with the hope of garnering more support and funding for restoring the bridge by 2017. The Green Bridge won the award by collecting 31 votes (or 41%), beating out the Split Rock Bridge in Pipestone County (15 votes or 20%) and a drone photo of the BB Comer Bridge in Alabama (7 votes or 9%)
1. Green Bridge in Des Moines, Iowa (by Mitch Nicholson) 31 votes (41%)
2. Split Rock Bridge near Pipestone, Minnesota (by Sebastian Renfield) 15 votes (20%)
3. BB Comer Bridge in Jackson County, Alabama (by David Kammerer) 7 votes (9%)
Forth Railroad Bridge in Scotland. Photo taken by Mark Watson
Mark Watson, an engineer based in Scotland, is an expert in bridges in his region and found some unique angles of two of the bridges for this awards- the Firth of Forth Railroad Bridge and the Forth Roadway Bridge. The former is slated to become a UNESCO World Hertiage Site this year, while the latter turned 50 last year. Both bridges won gold and silver respectively, with the latter sharing the silver metal with a photo of another unique bridge in neighboring England, the Clifton Suspension Bridge (taken by Laura Hilton). Here are the final results:
T3. Monks Bridge at Isle of Man (Liz Boakes) and Millau Viaduct in France (Jet Lowe)- 2 votes (11%)
This year’s category features five candidates as well as three post humus, the latter of which will be featured in separate articles coming out in the Chronicles. Two of the candidates come from Generation X (born between 1970- 1985) but have vast experience with developing their database on historic bridges in the United States- namely, James Baughn of Bridgehunter.com and Nathan Holth of HistoricBridges.org. Yet experience always trumps youth, as seen with the winner of this award, Jet Lowe. For over 30 years, Mr. Lowe has been the eye of bridge photography for the National Park Service (and more so with the Historic American Engineering Record), photographing bridges big and small. Because of his expertise, this year’s Lifetime Achievement goes to him. The Chronciles has contacted him for a 1 to 1 interview and will post the results soon, once it is finished.
1. Jet Lowe 10
2. James Baughn 6
3. Nathan Holth 5
4. Nels Raynor 3
This category had perhaps the highest number of entries but the lowest number of votes. Nevertheless, the winners were found in both the USA and International subcategories. For the USA, the Fink Truss Bridge in San Antonio, the work of a German local, barely got the prize, beating out the Saylorville Bridges in Iowa and the Silent Shade Bridge in Mississippi by only one vote, as well as an abandoned truss bridge in Minnesota by two. In the International part, Theoderich the Great received his Lifetime Legacy Award post humus, albeit 1500 years late, as his Rome aqueducts shared first place with a bowstring arch bridge in Japan, whereas the Ravenna aqueducts finished second. Despite the plea for more information on the age of the structure, the Drew Bridge, originally from Brazil but now residing in Florida, finished third.
1. Fink Truss Bridge in Texas (40%)
T2. Saylorville Lake Bridges (20%)
Silent Shade Bridge
3. Queenpost Bridge in Jackson Co., MN (17%)
T 1. Aqueducts of Rome and Bowstring Arch Bridge in Japan (38%)

To start off the Author’s Choice Award version of the 2014 Ammann Awards, presented by the Bridgehunter’s Chronicles, I would like to present you with an overture which is in connection with this year’s theme: Bigger is not always better. Enjoy!
This year’s Author’s Choice Awards features some of the most interesting stories of how people have come together to save their valued work. However, we have a story of a bridge found underneath a pub, as well as a failed attempt to salvage a historic bridge, and a disaster caused by gravity. And finally stupidity at its finest- caught on tape and youtubed! So without further ado, here are my pics for 2014:
Most Spectacular Disaster:
Ledbetter Bridge in Kentucky-Spanning the Tennessee River, this 1931 three-span polygonal Warren through truss bridge was one of the latter works of architectural art built by Polish engineer, Ralph Modjeski (1861-1940). The bridge no longer exists as it was removed last month, several weeks after a replacement span 700 feet downstream opened to traffic, but one cannot help but watch sections of the bridge collapse on its own, as seen in the photo gallery here. After reporting one of the approach spans dropping by two feet in 24 hours, officials fenced off the entire bridge, only to later watch sections of it fall on the shoreline. Cause: Erosion undermining the piers, plus some vultures perching on the railings of the affected spans, as the photographer stated.
Cherryvale Bridge in New Brunswick, Canada- Covered bridges have been especially hardest hit this year, as fire, oversized trucks and natural disasters have damaged or destroyed over three dozen bridges in North America and elsewhere. The Cherryvale Bridge in the province of New Brunswick was one of those unfortunate victims, as floodwaters knocked the 1870s wooden structure off its foundations in May, and the structure flowed downstream before being smashed against a concrete bridge carrying a highway. More on this story here. As beloved as they are, covered bridges are usually rebuilt by demand from residents. This is the case as well, but will it happen with this bridge? We’ll have to see….
Best Historic Bridge Find:
Rocky Balboa Railroad Bridge in Durham, North Carolina- This railroad underpass, featuring a 100-year old deck plate girder span, may be a typical bridge accomodating rail traffic. But (and the music from Rocky Balboa will support this), it has had a record of annihilating semi trucks and trailers, as well as tractors, busses, and other overweight vehicles. This DESPITE having every form of warning system and sign in place. Here’s a video to prove it:
The Parade Bridge in Norwood (South) Australia- Australia has a wide variety of metal, concrete and wooden bridges dating back to the early 1800s. This bridge, located underneath a pub, was found by chance by the owner as the venue was undergoing extensive renovations. Made of parapet and cobblestone and built in the 1850s, this bridge has a unique history, which can be found here.
Honorable mentioned: The Kersten Miles Bridge in Hamburg, Germany- Built in 1897 and named after the mayor of Hamburg during the Medieval times, this arch bridge is one of the darlings of Hamburg one needs to see, if one wants to know which of the 2,500+ bridges should be visited in the second largest city in Germany. Apart from its ornamental appearance and the fact that the bridge is made of brick, a recent discovery of a pflaster mosaic underneath one of the spans is another reason to visit this unique landmark. More on this discovery can be found here.
Best Way to Salvage a Historic Bridge:USA:
San Francisco-Oakland Bay Bridge East Span- The 1936 eastern half, consisting of cantilever truss spans, was replaced with a cable-stayed span with concrete girders last year and is still being dismantled even as we speak. Yet one person is looking at salvaging parts of the bridge for sustainable housing developments. Although it would look unusual to today’s housing standards, as seen in the article here, it would at least preserve the legacy of the eastern half of the bridge, which partially collapsed in the earthquake in 1989.
Also worth mentioning: Devil’s Elbow Bridge in Pukaski County, Missouri- The Freedom Prime Bridge and this bridge were two of the candidates considered for the author’s choice awards. Yet while Freedom received some accoldaes for best preservation example, this 1923 two-span Parker truss bridge got this one for two reasons: 1. The bridge was part of the Mother Road (Route 66) and because of the importance of the crossings along the highway that had once connected Chicago and Los Angeles, efforts are being undertaken to save what is left of this historic highway. 2. The bridge underwent an extensive renovation, which included new decking, sandblasting and repainting the trusses and making the bridge look just like it was when opened 91 years ago. The bridge should set an example for a pair of other crossings that have recently been rendered unsafe and whose futures are in doubt. More here.
International: Katzenbuckel Bridge in Ebenhausen, Bavaria (Germany)- Spanning a rail line near Augsburg in Bavaria, this arch bridge was in the way of progress, for the German Railways want to expand the line and electrify it. The solution: Instead of razing the structure because of its historic significance, the plan is to raise the bridge to better accomodate traffic. Impressive but also one that will have other regions with similar bridges to consider this option, for there are enough candidates to go around. More on the plan can be found here.

Worst Example of Restoring/Using a Historic Bridge
USA: Blue River US 40 Bridge in Kansas City, Missouri- Preservationists and locals are scratching their heads about this 1931 bridge, a steel through arch bridge that is the product of a pair of local bridge builders. The bridge was dismantled to make way for its replacement in August, but in a way that the parts were cut apart and left in a pile, waiting to be taken to its new home in Grandview. Photos of the bridge before and after its dismantling can be found here. Given the “logic” behind this process, the first and foremost question that comes to mind is: How are you going to put the structure back together again without altering its historic integrity? Or are you going to scrap it? My prediction: Its induction into Nathan Holth’s Wall of Shame.
International: Kramer Bridge in Erfurt, Germany- This bridge in the news but in a negative sense. The face of Thuringia’s capital was the focus of a drug operation, used in the German mystery series, Tatort (Scene of the Crime). The episode was aired in December and drew fire from viewers who deemed both the usage and the content to be inappropriate. Shortly after the release, two of the three actors resigned and the German channel MDR decided to scrap the Erfurt series. Lessons on how Tatort should be produced and how places of interest should be used without degrading it should be given by those who have been with the series for over 2 out of the four decades of its existence on German TV, including the likes of Ulike Folkerts, Axel Prahl and Jan Josef Lieffers, who play investigators for their cities (Ludwigshafen and Muenster, respectively.)
Biggest Bonehead Story We had a lot of candidates for this category, many of whom just could not learn to shorten the height of and/or lighten the weight of the load. The end result: covered bridges losing their tops and other bridges dropping to the ravine with their load on it. Yet only two examples really standout and should serve as a signal to truck drivers to NOT rely solely on GPS and assumptions, but to obey the traffic signs, or face liabiity.
Pollock’s Mill Bridge in Jefferson, Pennsylvania- Spanning Ten Mile Creek near Jefferson, this single span Whipple through truss bridge, built in 1878 by the Massilon Bridge Company in Ohio is one of the last remaining iron bridges in western Pennsylvania. Yet it almost became a hunk of twisted metal after a tanker truck tried crossing the structure, only to fall partially through the decking. To make matters worse, the driver dumped liquid contents into the stream to lighten the load and keep it from collapsing. A double-environmental catastrophe. Yet with two trucks following him, he should have known better than to first drive through the height restricted underpass located just a half mile before the bridge and then try crossing this bridge, right? Leadership prevents stupid things from happening. Fortunately, the bridge will be repaired and nothing was severely adversed in the water. However, as the article stated here, it could have been worse…..
Watford Bridge in North Dakota- Spanning the Little Missouri River at US Hwy. 85, this Warren through truss with V-laced portal bracings has dealt with a lot in the 55 years in service, especially as it is located near the Bakken Oil Fields. This includes oversized vehicles crossing it and damaging the overhead bracing. Sometimes stupidity is best shown on video, and the truck driver probably did not realized how much of an idiot he was for ignoring the height restrictions until watching the amateur video taken by another truck driver and his passenger, who spiced it up with some commentary (Note- some comments may not be suitable for children under 13.)
This sums up my picks for 2014. As you can see, we had some interesting stories, all caught on photos and film in hopes that drivers pay attention to their load when using the bridges. Because even the most modern bridges can only take so much. Take this advice in mind: Less is Always More, regardless of the gas price. After watching the videos and reading the articles pertaining to the bridge picks, have a look at the winners of the 2014 Ammann Awards coming up in the next article…..
Oberbaum Bridge and Viaduct spanning the Spree in Berlin. Photo taken in June 2010
This is a joint article with sister column The Flensburg Files and is part of the Files’ series on the 25th Anniversary of the Fall of the Berlin Wall and German Reunification. For more information on this series, please click here for details.
Berlin: The capital of Germany and one of the most cosmopolitan cities in the world. With 3.5 million inhabitants, the city is the cultural center and a major tourist attraction for people to see. A person can take a morning boat tour along the Spree, have lunch at a Christmas market at Alexanderplatz, see the entire city from the TV Tower (Fernsehturm), take in a concert with the city’s philharmonic orchestra at Gendarmen Market, visit the museums along Unter den Linden, consume and buy tons of books at Dussmann in Mitte, and lastly, eat a Vietnamese meal at a restaurant at Prenzlauer Berg. This is a typical day for a tourist visiting Berlin. With children, it would be crime not to visit the Zoo and Tiergarten in Charlottenburg.
Yet Berlin (like the rest of Germany) for almost five decades had been a chessboard for conflict between the Soviet Union and the United States. The City was divided into four sectors in accordance to the Yalta Agreement signed on the eve of the end of World War II, yet instead of helping the Germans in the eastern sector rebuild their livelihood, the Soviets erected the Berlin Wall on 13 August 1961, keeping the easterners from fleeing to West Berlin. For 28 years the Wall became the symbol of a divided Germany with each half having a different government and different mentality. This held true until 1989, when protests by the hundreds of thousands, resulted in the fall of the East German dictator, and subsequentially, the fall of the Wall. The first border opened on 9 November, 1989 and by the beginning of 1990, the Wall was but a memory and Berlin, reunited.
The 40+ kilometer long Berlin Wall not only surrounded West Berlin and closed off any possibilities to escape, it also blocked access to the bridges that spanned many of Berlin’s waterways, whether it was the Spree, the Teltow Canal or Wannsee. Many of the important crossings became the bridges to nowhere for 28 years, until the Wall fell and the crossings were reopened for the first time. Some of the bridges became the point of exchanges of Soviet and western agents, others allowed only westerners to visit East Berlin but not the other way around. But nonetheless, all of the crossings are open today, and people can use the bridges without having to show the border guards their passports, let alone fear for being arrested and charged of espionage.
The Chronicles will feature six well-known crossings that had once been either closed off by border guards or walled off completely, to show how important they were both during the Cold War as well as at the time of the Fall of the Wall, and to compare their relevance then to today, as Berlin celebrates its anniversary of the revolution that ushered in a new and peaceful era. A couple of these crossings have recently been torn down but not before leaving a historical marker indicating their importance in connection with one of the most painful times Berlin and the world faced.

Oberbaumbrücke and Viaduct
Location: Spree River at Am Oberbaum between Friedrichshain and Kreuzburg
Built: 1896; rebuilt in 1948 and 1995
Description and History: The Oberbaumbrücke is one of Berlin’s prized treasures. The bridge features two levels of brick arch spans- the lower deck has six arches plus a steel beam center span to allow for ships to pass. That serves vehicular and pedestrian traffic. The upper deck features brick arches creating an arcade below for people to walk underneath. The center span features a steel deck arch span. The outerriver spans feature steel deck trusses that cross the streets below. Since 1995, the upper deck has served subway traffic. The bridge is highly ornamented with gothic towers, using the tower of the Mitteltorturm in Prenzlau (located 90 km north of Berlin) as a reference. The largest of the two are located at the center span of the bridge.The total length of the bridge is 150 meters not counting the steel truss viaducts on the Kreuzburg end. The bridge suffered substantial damage in World War II with the gothic towers being destroyed and the upper deck being damaged to a point where no vehicles could cross. Although it remained in place, it was closed to traffic with the completion of the Berlin Wall in 1961. Yet with the fall of the Wall in 1989, plans were undertaken to restore the bridge to its original form. This was done between 1992 and its completion in 1996 with the steel center arch span being built by world famous architect, Santiago Calatrava. Since then, the bridge has retained its original features, although remnants of the Cold War can be seen- the watch tower and portions of the Berlin Wall can be seen at the bridge, serving as a reminder of a divided Berlin during the 28-year period of the Wall. Since 1991, the boroughs of Friedrichshain and Kreuzburg have been a joint community and since 1998, festivities have occurred on the bridge, including a water fight between residents of the two communities as well as an art festival.

Location: Havel River at Bundesstrasse 1 between Berlin- Wannsee, Babelsberg and Potsdam
Built: 1907 (current bridge); rebuilt in 1947
The 128 meter long Glienicke Bridge is located at the very southwest portion of Berlin. Built in 1907 by the Hakort Bridge Company of Duisburg under the direction of Eduard Fürstenau, this steel cantilever Warren truss bridge is the third crossing at this site, with the first crossing made of wood being built in 1670 followed by a stone arch bridge replacing it in 1834. Despite protests by residents of Potsdam and Berlin, that bridge was demolished in 1904 as part of the plan to expand the Teltow Canal. Construction on the new bridge began two years later. The bridge became the key link between the two cities afterwards, with the federal highway 1 crossing it. It was widened to accommodate traffic in 1937 and was the most traveled highway until it was partially destroyed at the close of World War II in 1945.
It was rebuilt in its original form two years later but became the dividing point between the Soviet Zone and that of the US and later its allies. When the Berlin Wall was constructed in 1961, a barrier and border control area was constructed at the Potsdam end to prevent East Germans from fleeing into West Berlin. Up to 1989, only one escape attempt was successfully made, which was a Trabant car smashing through the wall in 1988, smuggling three people across the border into West Berlin. If there was a bridge where Soviet and Western Spies were exchanged often, this bridge was the place. Between 1962 and 1986, three exchanges of spies took place, based on agreements made between the US and Soviet Union. A video of the “Bridge of Agents”, as coined by many, can be seen below.
After the Wall fell in 1989, the bridge was reopened and later restored to accommodate traffic between Berlin and Potsdam, and to this day, the key link between the two cities has been reestablished. Despite dismantling the wall and the border areas, a memorial and museum dedicated to this key crossing, was built near the stone columns on the Potsdam side. It is open daily for those wanting to visit the bridge and learn about its unique history.

Location: Railroad and Light Rail Lines at Bornholmerstrasse between Prenzlauer Berg and Gesundbrunnen
The Bösebrücke is 320 meters long and features a steel through arch design, with the upper chord and approach spans being a Warren truss design. The bridge was one of a few that survived World War II but was even more unique for it was the first border crossing to be opened on the night of 9-10 November, 1989, allowing people to cross between East and West Berlin. A video of the event can be seen below. Several memorials can be found on or near the bridge commemorating this historic event, for the bridge served as an example of how a border literally became a bridge. Other border crossings followed and within 48 hours, the border crossings were open, and the Wall came tumbling down, piece by piece. The bridge still serves as a key crossing today, although its significance has diminished since 1989. The Bösebrücke does not necessarily mean “Bad Bridge,” it was named after Wilhelm Böse, who was one of many opponents of Adolf Hitler that led a resistance movement in an attempt to bring him down. Unfortunately he failed and was subsequentially executed on 21 April, 1944.

Location: Teltow Canal at Berlin Zehlendorf
Built: 1906, demolished in 1990, new structure built in 2009
Named after a prominent politician Leo Wilhelm Robert Karl von dem Knesebeck, this crossing featured a Warren through truss design with Warren portal bracings, all covered with ornamental decorations. This bridge was the most ornamental of the bridges along the Berlin Wall, yet it was made obsolete with the construction of the Berlin Wall in 1961. A barrier was constructed at the bridge’s east portal and remained there until 1989. The bridge was torn down after the Fall of the Wall and replaced with a temporary crossing. A permanent crossing- a steel beam contraption- was built in 2009 and has provided drivers with a crossing over the Teltow Canal ever since.
The S-Bahn Crossing at Liesenstrasse
Location: Liesenstrasse, Gartenstrasse, and Ackerstrasse between Berlin-Mitte and Berlin-Gesundbrunnen, north of Stettin Station
Built: 1892 replacing a bridge built in 1843, abandoned since 1952
Featuring two curved Whipple through truss spans and one plate girder span, the Liesenstrasse Bridge once featured a rail line that started at Stettin Station and headed north towards Poland. It was one of a few bridges that survived unscathed by World War II, but unfortunately, with the destruction of the Stettin Station thanks to Russian bombs, combined with the construction of the Berlin Wall along Liesenstrasse in 1961, the crossing was rendered useless and has been sitting abandoned for 62 years. Even after the Berlin Wall fell, no consideration was made regarding the future of the bridge and the rail line. However, most recently, a grassroots group was formed with the goal of converting the bridge and the rail line to a bike trail. Already a presentation was given during the German heritage days, but more help is needed. More information on the bridge and the preservation group can be found here and here. The bridge is already protected by preservation laws, and is in an area where tourists can find several cemetaries nearby, as well as remnants of the Berlin Wall on the western side of the bridge.
Truss crossing and the Berlin Wall. Source: http://commons.wikimedia.org/wiki/File%3AWiener_Br%C3%BCcke_Berlin_01.jpg
Location: Landwehrkanal at Karl-Kunger-Strasse in Berlin-Kreuzburg
Built: 1896 (concrete arch bridge), destroyed in 1945, replaced with truss bridge in 1946, removed in 2000
The last bridge to be profiled here is the Wiener Brücke (Vienna Bridge), a bridge with a tragic story behind it, especially as you see in the picture above. The original bridge consisted of a closed-spandrel concrete arch bridge with ornamental features resembling round emblems on the spandrels, Hermann Rhode and E. Simanski were the engineers behind the bridge that took a year to build. On 23 April, 1945, in an attempt to hinder the advancement of the Soviet Army, the Nazi troops detonated the arch bridge. Two of the emblems survived the blasts and were recovered and later taken to a cemetary at Berlin-Heiligensee to serve as a memorial for the people lost in the war. It took 12 years until its replacement was erected- a Warren half-deck and half pony truss span, which connected Kreuzburg with Treptow. Yet the crossing was made obsolete less than four years later with the construction of the Berlin Wall in 1961. The bridge remained unused until the Wall fell and the crossing was reopened to traffic. Yet it would only serve pedestrian traffic until it was finally demolished in 2000. At the present time, no replacement was planned.
There are many other crossings that are worth mentioning, but these are the key ones that serve as a reminder of how the Berlin Wall effectively kept people from crossing between the two halves of Berlin during the Cold War. And even if Berlin is a unified city today, with no external influence from the allies, one cannot forget about the history of how it was divided, and how these bridges kept the city together through the times of war and after the Wall finally fell and Germany was reunified.

Once you have a chance to look at the photos, please click on the link below and vote for your favorite candidate. Note: As the photos are divided into the categories of USA bridges and International, there are two links you need to be aware of:
James Baughn: Since 2002, James Baughn has run his website entitled Bridgehunter.com. First focused on historic bridges of the midwestern part of the US, his website now has a databank of over 40,000 bridges, 80% featuring photos from over 170 contributors, including the author of the Chronicles. Baughn hosts the TRUSS Awards every February, where historic bridges threatened with demolition are recognized, giving locals and other preservationists more fuel to save the bridge. More on his website here: http://bridgehunter.com/
Jet Lowe: An avid photographer, Jet has photographed thousands of historic bridges, big or small in the past 30+ years, while working for the Washington-based Historic American Engineering Record, a subsidiary of the National Park Service. More about him, you’ll find here: http://www.loc.gov/pictures/search/?q=Jet%20Lowe He submitted a photo of the Millau Viaduct for this year’s Best Photo Award.
Nathan Holth: At 28 years of age, Nathan Holth is the youngest candidate for this award. And that is no surprise, for his website, HistoricBridges.org, which has been in syndication since 2003, features nearly 4,000 bridges in North America (all fully photographed), web pages with guides on how to preserve historic bridges and his famous Wall of Shame, a list of historic bridges of high value that were scrapped senselessly, without looking at other alternatives to saving them. More on him can be found at his website here: http://historicbridges.org/
Nels Raynor of BACH Steel: With over three decades of work, Mr. Raynor has had a lot of accomplishments under his belt not only as far as restoring historic bridges are concerned, but also teaching many how to do it, so they can try it as well. More about him and his company here: http://bachsteel.com/
Friends of Bunker Mill Bridge: Consisting of several dedicated people of all ages, this group of preservationists have gone all out in saving the Bunker Mill Bridge outside Kalona, the bridge that was badly damaged in a fire in August 2013 but they are working to rebuild. This includes hosting open air concerts and having a small shop at the bridge, with money raised going to the rebuilding efforts. Link: https://www.facebook.com/groups/582901311753226/
Fehmarn Bridge in Germany: Connecting the German mainland with the largest island in Europe, this 51-year old bridge was the first of its kind to introduce the now popular basket-handle arch bridge. That is why residents are fighting the attempts by the German Railways and the state to replace it with a tunnel and tear this “Merkmal des Insels” down. More here. A petition to save the bridge and block a proposal for three bridges can be found here.
Linz Railroad Bridge in Austria: The three-span steel bridge, built in 1912 and spanning the Danube River, has been a focus of a struggle between the modernists of the Social Democrats and Mayor Luger who want the bridge replaced and the preservationists and citizens who want the bridge saved, or at least bring the referendum on the bridge’s future to the attention of the city. Link: http://thebridgehunter.areavoices.com/2014/08/05/linz-railroad-bridge-preservation-interview/
Clifton Suspension Bridge in Bristol: Before John Roebling built the first wire suspension bridges in Cincinnati and Brooklyn, Ishmail Brunel built the highest and longest chain suspension bridge over the River Avon. It was his first solo project for the engineer but died before the bridge opened in December 1864. This year marks the 150th birthday of one of England’s beloved bridges. Link: Clifton Suspension Bridge Homepage
Firth of Forth Bridges in Scotland: The duo crossings feature two unique bridges: the first steel cantilever truss bridge opened in 1890 and is scheduled to be a UNESCO World Heritage Site and a roadway suspension bridge built next to it and is 50 years old this year. You can see the photos submitted by Mark Watson in the category of Best Photo. More about the history here: http://en.wikipedia.org/wiki/Forth_Bridge
Tower Bridge in London: This bridge is perhaps the cornerstone of bridges built during the Victorian era, as it was built in 1894 and features a combination suspension and draw bridge. It just celebrated its 120th birthday this summer and now has a new glass platform where people can look down from the towers. More here: http://www.towerbridge.org.uk/
Natchez Trace Parkway at Birdsong Hollow, TN: This soon-to-be 20-year old bridge is unique not only because of its design and its conformity to the environment, but also its height above the Harpeth River Valley- 150 feet above the valley floor. Calvin Snead has a brief summary on this bridge here.

Here are the list of candidates for the 2014 Ammann Awards in the category of Best Kept Secret in the areas of individual bridges and regions with a high number of historic and aesthetically significant bridges. Have a look at the summary and links of the candidates before voting using the links below:
Independence Bowstring Arch Bridge in Independence, Kansas- Built in 1871, this iron bowstring arch bridge is an earlier work of the King Bridge Company in Cleveland, OH. The bridge has been abandoned since 1964 but given its proximity to the city of Independence, it may have an afterlife in a few years. Link: http://bridgehunter.com/ks/montgomery/independence-bowstring/
Front Yard Bridge in Packwood, Washington: Photographer and pontist K.A. Erickson found this bridge sitting on the lawn of a property owner, who purchased the bridge and had it relocated to its present spot. Given the railing features, the concrete bridge dates back to 1915.
Fort Morgan Rainbow Arch Bridge in Colorado: Built in 1923, this 11-span Marsh arch bridge with a total span of 1,100 feet was the longest bridge of its kind when it was built. It has been converted to a pedestrian crossing, providing walkers and bikers with a splendid view of the South Platt River. Link: http://bridgehunter.com/co/morgan/fort-morgan/
Powwow River Polygonal Truss Bridge in Amesbury, MA: This bridge is one of the smallest polygonal through truss bridges ever built. It is a question of what truss design it features. More here.
Clarendon White River Bridge in Monroe County, AR: Spanning the White River, the Clarendon Bridge is one of three sister bridges spanning the White River in Arkansas. Yet the cantilever truss bridge’s future is in doubt as a replacement bridge is being built. Yet efforts are being made to preserve and restore it for bike trail use. More here.
River Durme Bridge in Hamme, Belgium- This bridge has a history in itself as it featured a three-span curved Town lattice pony truss bridge, carrying rail traffic and built in ca. 1870. Yet the center span of the bridge was destroyed by German troops during World War I and was subsequentially replaced with a swing span with Warren truss features. This bridge still serves traffic today.
Monks Bridge on the Isle of Man (the UK)- Located in the northernmost province of the United Kingdom, this bridge features one of the oldest examples of stone arches designed gothically. Possibly built during the Roman era, this bridge is one of the oldest existent structures in the British Isles.
Oschutztal Viaduct in Weida, Germany- Located in the German state of Thuringia, this iron deck Town Lattice deck truss bridge spans the valley where the village of Weida is located. Once serving rail traffic connecting Greiz and Gera, the bridge was abandoned in the 1980s but plans are in the making to repurpose the structure for recreational purposes, especially as it just turned 130 years old this year. Link with photos: http://www.viadukt-weida.de/
Lindaunis Schlei Drawbridge in Eckerfoerde, Germany- Located in the German state of Schleswig-Holstein, this combination Strauss Bascule pony truss bridge and Warren bedstead through truss approach span was built in 1927 and serves rail traffic between Kiel and Flensburg. Yet its future is in doubt as plans are underway to replace the structure. More here.
Swimming Bridge in Wuppertal, Germany- Located in North Rhine-Westphalia near Dortmund, this bridge is a primitive version of the pontoon bridge, with a catwalk being supported by boats. More here.
Pont de Langlois / pont Van Gogh, Arles – Bouche-du-Rhône; France- Spanning a small canal in Arles, France, this bridge was the subject of many paintings by Dutch artist, Vincent Van Gogh. A replica of the double leaf bascule bridge retains its original form and is still a popular attraction today. Link: http://en.wikipedia.org/wiki/Langlois_Bridge
The Bridges of Prague, Czech Republic: Over three dozen bridges can be found in the Czech capital, most of them over the Charles River, including the city’s beloved Charles Bridge, built in the Medieval period and still attracts many tourists. Link: http://www.1pragueguide.com/bridges-in-prague
The Bridges of Budapest, Hungary:The Danube divides the Hungarian capital into Buda and Pest, but several crossings, including the Chain Suspension Bridge, Margaret’s Bridge, Liberty Truss Bridge and Langomanyos Bridge tie the city together. Link: http://www.bridgesofbudapest.com/
The Bridges of Manchester, Great Britain: Once known as one of the dirtiest industrial towns in England, the second largest city behind London is now a huge financial hub, with several bridges, like the Salford Quay, the Blackfriar’s and Albert Bridges connecting the districts. Link: http://manchesterhistory.net/manchester/bridges.html
The Bridges of Sault Ste. Marie, Michigan/Ontario: If one thinks of Sault Ste. Marie, one can think of the International Bridges and their double-arches. Yet, there are at least seven more bridges to see on both sides of the border when looking down from the viaduct. This includes two steel arches and a multiple-span steel truss bridge with a vertical lift span, just to name a few. More on the bridges here.
The Bridges of Pittsburgh: The city has a lot to be proud of, apart from the Steelers, Pirates and Penguins. The second largest city has a wide array of historic bridges spanning three rivers, among them: the Smithfield, Hot Metal, Warhol, Carson, Clemente, Dusquene, Fort Pitt, Manchester, and Point Bridges, just to name a few. The Pittsburgh Gazette did a series on these bridges which you can view here: http://newsinteractive.post-gazette.com/bridges/monongahela/
The Bridges of Doniphan County, Kansas:Located west of St Joseph, this county features a variety of unusual bridges, reused with parts salvaged from other structures. More here.
The Bridges of Bertram, Iowa: Located east of Cedar Rapids, this community has a wide selection of truss bridges dating back to 1885, including the now destroyed Ely Street Bridge. More on the bridges here.
The Bridges of Miami County, Kansas: This county features several truss bridges, including the reverse Parker truss bridge, several arch bridges and two Marsh Arch bridges. It is perhaps the most populous in the state when it comes to historic bridges. Link: http://bridgehunter.com/ks/miami/
The Bridges of Camden State Park in Minnesota: Located southwest of Marshall in Lyon County, the park features remnants of the village of Camden, located in the Redwood River valley. This includes the bridges serving the park, all but one of which are scheduled to be replaced in the near future. More here.
