The Mederville Bridge is a historic structure located in the unincorporated community of Mederville, Iowa, United States. It spans the Volga River for 156 feet (48 m). This is one of only a few open spandrel arch bridges constructed in Iowa. Designed by the Marsh Engineering Company of Des Moines, it replaced a covered timber Howe truss bridge. Clayton County rejected all of the original bids to build the structure when they all came in too high. Six companies bid a second time on the project, and F. E. Marsh and Company of Des Moines won. They completed in the bridge in 1918 for $17,454.32. It was listed on the National Register of Historic Places in 1998.
