Mederville Bridge, Spanning Volga River at County Road C5X, Mederville, Clayton County, IA
Summary
Significance: The Mederville bridge is technologically significant as one of the earliest open-spandrel arches built in Iowa where relatively few were ever built. Meant to be an economic alternative to the steel truss for wagon bridge construction, the open-spandrel concrete arch at Mederville spans 155', and is an example of the rather uncommon use of concrete arch technology employed in spanning wide crossings.
