Description 

The Nodaway River bridge is an 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. During this period many thousands of bowstring arch-trusses were built throughout the nation. Because the development of Iowa's road system coincided with this period, the number of bowstrings built in the state numbered in the hundreds. Most of these were built by the large Ohio bridge companies, such as the King Iron Bridge Company, and the Massillon Bridge Company. The Nodaway River bridge is an excellent example of a bowstring arch-truss that was built by a smaller company: the Missouri Valley Bridge and Iron Company of Leavenworth, Kansas. -- Historic American Engineering Record (HAER IA-68)
