New Richmond Swing Bridge

The New Richmond Swing Bridge, also known as the Fifty-Seventh Street Bridge, is a one lane swing bridge in Michigan. Located in Allegan County's Manlius Township, it connected 57th Street with Old Allegan Road over the Kalamazoo River until its closure to vehicular traffic. The name New Richmond comes from a former mining town in the area of the same name. The bridge is one of the oldest - if not the oldest - swing bridges extant in the United States, and is one of the oldest metal truss bridges in the state of Michigan and the state's longest pony truss bridge.
