Description 

In February 1873 the Van Buren County Board of Supervisors contracted with the Wrought Iron Bridge Company of Canton, Ohio, to build a major wagon bridge over the Des Moines River at Keosauqua. Comprised of four bowstring arch-truss spans, supported by massive stone piers with tapered upstream cutwaters, the Keosauqua was the county's first major all-iron structure. WIBCo used its patented, tubular bowstring design, completing the structure by September of that year. As a pivotal crossing at the county's center, the Keosauqua Bridge carried heavy wagon, and later automobile, traffic for some 65 years. By the late 1930s, however, the original bridge showed signs of wear and created a bottleneck to traffic with its narrow roadway. In 1938 the Iowa State Highway Commission designed a replacement superstructure for the bridge, to be placed on new concrete caps that flared over the original stone abutments and piers.
