U.S. Route 10

U.S. Route 10 is an east–west United States highway formed in 1926. Though it never became the cross-country highway suggested by the "0" as the last digit of its route number, U.S. Highway 10 was one of the original long-haul highways, running from Detroit, Michigan, to Seattle, Washington, but then losing much of its length when new Interstate Highways were built on top of its right-of-way. In 2010, its length is 565 miles (909 km).

U.S. Highway 10 is broken into two segments by Lake Michigan. Travel between the two segments is possible on a seasonal basis via the ferry SS Badger between Ludington, Michigan, and Manitowoc, Wisconsin. The ferry route and link are not part of the U.S. Highway system.

The eastern terminus of U.S. Highway 10 is in Bay City, Michigan, at its interchange with Interstate 75 (near Highway 10's milepost 139 and Interstate 75's milepost 162). The western terminus of U.S. Highway 10 is in the town of West Fargo, North Dakota, at its interchange with Interstate 94.
