Name that bridge type: A bridge type making a comeback

Photo taken in August 2009

While truss bridges are making their comeback in a modern form to serve as either a pedestrian or vehicular crossing, this bridge type is rumored to be coming back as well. This is the subject of the Bridgehunter’s Chronicles’ Pop Quiz.

This bridge was the first of its kind to be built in the United States and one of the first to be listed on the National Register of Historic Places. The bridge design was conceived by an Austrian engineer but this bridge was built by a German engineer. Even though the bridge type became popular during the first four decades after this bridge was built in the 1890s, it fell out of favor for concrete beam bridges for the next 60 years. Yet this has started coming back into popularity as the second most commonly used short-span crossing, behind the culverts. Reason: culverts cause back-ups, flooding and erosion. This type can allow water to flow freely under the roadway, alleviating the headaches of farmers and eventually the local politicians who have to take the heat from these particular farmers for making the illogical, cheap decision to install them over normal bridges to begin with.  The bridge in the picture was relocated to a park in the 1960s and serves as one of the masterpieces of a local rural community in the Midwest.

Now it’s your turn! Name:

1. The bridge type and who designed it,

2. This bridge in the picture, who built it and where it’s located, and

3. Another example of a bridge type that’s in existence, both past and present.

The answer will be revealed next week on Tuesday. Until then you can plaster the article or facebook webpages with your answers. Good luck! :-)
