The Adair Viaduct spans the Iowa Interstate Railroad for 192 feet. The first bridge was built in 1908 over the Chicago, Rock Island and Pacific Railroad tracks. Increased traffic by the 1920s necessitated its replacement. The Iowa State Highway Commission designed the three-span open spandrel arch bridge. It is somewhat unusual in Iowa in that the bridge is not symmetrical. The bridge was opened to traffic in June 1924. It was listed on the National Register of Historic Places in 1998.
