Originally it carried US 20. It was built in 1934 by the Weldon Brothers for $51,710.55.[2] In the 1920s and 1930s if a relatively long bridge was required in a rural area, it would have been built using steel trusses, but in this urban setting where there is enough height in the bridge to allow wide arches, a concrete open spandrel arch bridge could be built, and be worthwhile for its attractiveness. In Iowa the Mederville Bridge (1918), the Adair Viaduct (1923) and the Iowa Falls Bridge (1928, also built by the Weldon Brothers) are other examples, but the Washington Avenue bridge is notable as a well-preserved two-span example.[2] It was listed on the National Register of Historic Places in 1998.[1] See also
