After a long absence, the mystery bridge series takes us back to Harrison County, Iowa. Except the main focus is not on the Buellton Bridges that made their way to the county and all but one of which have vanished into the history books. Nor does it have to do with the Orr Bridge, which met its unexpected end at the hands of the tornado in 1999, after serving the county for 40+ years. The mystery bridge we’re looking at is located only three miles east of Logan, which is not only the county seat but was also nearly wiped out by the same tornado.

When one turns right onto 240th Street from US Hwy. 30 and drives 1.5 miles east, then one will find the structure on the right hand side. According to Googlemaps, it is on Pontiac Lane, just 400 feet south over a small creek, surrounded by three farmsteads. When looking at the bridge closely, one can rule out the Warren type right away as the Warren truss has W-framed diagonals. Judging by the number of panels the bridge has (ca. 10 panels) one can assume that the through truss bridge is either a Pratt, Whipple or even Howe type. Further descriptions of the bridge- the portal bracing and whether the bridge is pin-connected or riveted- cannot be seen from a distance.

Yet, the history of the bridge is similar to the ones mentioned in earlier articles. According to Craig Guttau, the bridge spans a small creek and may have been imported to the county in the 1940s. It served traffic for 20-30 years before being replaced with a concrete culvert, while realigning the road at the same time. The purpose of a straightened road was to eliminate sharp curves and accommodate farm traffic. But when the bridge was built and when it was abandoned in favor of the culvert are still open to be solved.

Can you help?

The task is simple: We need photos and information on the bridge, using the data below. You can post your photos on the Chronicles’ facebook pages, send the information to Jason Smith at the Chronicles, using the contact info provided in the About page, or post the info on the Bridgehunter.com page. In either case, bird’s eye views are good, close-up shots are better, but the stories behind the bridge’s life is always the best. Let’s complete the story about this bridge, shall we?
