It spans the Keigley Branch for {{convert|47|ft|m}}.[2] The Iowa State Highway Commission was re-formed in 1913 and they developed standard designs for smaller bridges. One of their designs was an alternative to the Luten arch. They were built throughout the state in the 1910s and 1920s. This is the oldest remaining arch bridge from that era.[2] The Koss Construction Company of Des Moines completed it in 1913 for $3,384.85. The bridge features a medium-span arch with concrete filled spandrels, paneled guardrails, a corbeled arch ring, and bi-chrome concrete detailing. It was listed on the National Register of Historic Places in 1998.[1] See also
