The S.S. Badger Car Ferry is Designated as the Continuance Route of Highway US-10
US-10 is an east–west United States highway formed in 1926. US-10 was one of the original long-haul highways which stretched from Detroit, Michigan, to Seattle, Washington, but then lost much of its length when new Interstate Highways were built in its right-of-way. Today, the eastern terminus of US-10 is in Bay City, Michigan, at its interchange with Interstate 75 (I-75) and the western terminus of US-10 is in West Fargo, North Dakota, at its interchange with I-94.
The American Association of State Highway and Transportation Officials (AASHTO) has designated the route traveled by the S.S. Badger across Lake Michigan as the official continuance route of US-10. Prior to this designation, Lake Michigan had separated US-10 in the port cities of Ludington, Michigan and Manitowoc, Wisconsin into two segments.Highway US-10 connects the states of Michigan, Wisconsin, Minnesota, and South Dakota by means of ferrying 60 miles across Lake Michigan. US-10 is one of only two United States highways utilizing a ferry service connection. The S.S. Badger plays a major role in providing connectivity of US-10 for travelers and commercial cargo in the upper Mid-West.
