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, 140 feet (43 m), and is built with three side-by-side arched ribs supporting concrete pillars.[2]
