The Shanaska Creek Bridge, also called Washington Park Bridge and officially Bridge 4846, is an iron 8 panel pin-connected Pratt through truss bridge which was erected in 1875 over the Blue Earth River in the U.S. State of Minnesota and moved twice since. It was built near Vernon Center, Minnesota by Soulerin, James, and Company of Milwaukee, Wisconsin. In 1929, it was placed over Minnesota State Highway 22 to carry Le Sueur County Road 102. It was the oldest bridge of its type left in the state when it was listed at that location on the National Register of Historic Places in 1981.
