Overview Looking Northeast

This bridge was moved here in 2006 from its original location. The bridge was moved by the National Guard, by helicopter, as part of a training exercise. Some folks referred to this as "The Flying Bridge" for some time afterward.

Description 

The three-span Hale Bridge is a striking, and extremely rare, example of what was once a common bridge form: the bowstring arch-truss. In the 1860s and 1870s bowstring arch-trusses were used extensively because of their great structural efficiency and relatively low construction costs. The Hale Bridge is an excellent example of the work of the King Iron Bridge and Manufacturing Company, a major bridge fabricator who erected a great number of this type of bridge throughout the nation, including in Iowa. -- Historic American Engineering Record (HAER IA-59)
