Tenth Street Bridge (Great Falls, Montana)

The Tenth Street Bridge is a concrete arch bridge in Great Falls, Montana, spanning the Missouri River. The bridge was designed by engineer Ralph Adams of Spokane, Washington and Great Falls architect George Shanley, and was completed in 1920. It was the longest open-spandrel ribbed concrete arch bridge in Montana.

The construction of a new bridge at Ninth Street in the 1990s made the bridge redundant, and it was proposed for demolition. Preservationists successfully diverted demolition funds to bridge preservation, and the bridge is being repaired to function as a pedestrian bridge between Great Falls and the Black Eagle community.
