The River Street Bridge over the Iowa River at Iowa Falls, Iowa is an open spandrel bridge built during 1922–1924. It was built by the Weldon Brothers at cost of $16,900, including removal of the previous bridge on the site. It is the fourth bridge constructed on the site, a "pivotal" location in Iowa Falls' development. It has a long span, 140feet, and is built with three side-by-side arched ribs supporting concrete pillars.[1]
The bridge was modified in 1958 by widening of its deck and replacement of its guardrails.[1] It was listed on the National Register of Historic Places in 1998.
