U.S. Route 10 (Michigan) is an east–west United States Numbered Highway that traverses the Upper Peninsula and the Lower Peninsula of Michigan, connecting Iron Mountain and the Saginaw Bay area. The route serves as a regional corridor linking U.S. Route 2, Interstate 75, and U.S. Route 23 while passing near communities such as Escanaba, Manistique, Ludington, and Bay City. The highway combines segments of two-lane rural road, expressway, and freeway near major crossings like the Masonboro Channel and the Saginaw River.

Route description

US 10 begins in Iron Mountain at a junction with U.S. Route 2 and proceeds eastward through Dickinson County and toward Escanaba via rural communities and woodlands near the Menominee River basin. The corridor intersects regional routes such as M-69 and M-35 before reaching the lake-shore community of Manistique on Lake Michigan. East of Manistique the highway continues across sparsely populated sections of Schoolcraft County and Mason County where it links to M-134 and M-63 before forming a ferry and port approach near Ludington and the SS Badger crossing to Milwaukee. Continuing across the Straits of Mackinac corridor is not part of US 10; instead the route turns southeast, joining or paralleling Interstate 75 briefly near the M-25 junction, and then proceeds toward the Saginaw Bay region. Approaching Bay City the highway becomes a divided expressway and connects to U.S. Route 23 and M-13 before terminating near Pere Marquette Township.

History

The US 10 designation was created in the 1926 American Association of State Highway Officials system and replaced earlier auto trails and state trunklines that served the Upper and Lower Peninsulas. Early routing reflected alignments used by the Lincoln Highway and local Good Roads Movement boosters; segments were subsequently improved during New Deal-era programs tied to the Works Progress Administration and later federal aid under the Federal-Aid Highway Act of 1956. Changes in the mid-20th century included bypass construction around towns like Manistique and Ludington and freeway upgrades near Bay City tied to industrial access for firms in the Great Lakes Steel and shipping sectors. Portions of former alignments were redesignated as state highways such as M-25 and county roads when the Michigan Department of Transportation completed expressway segments. Cross-lake ferry service by the SS Badger has long influenced US 10's role in interstate commerce between Michigan and Wisconsin.

Major intersections

- Western terminus: junction with U.S. Route 2 in Iron Mountain - Intersection with M-69 near Crystal Falls - Junction with M-35 near Negaunee - Connection to M-134 near De Tour Village (eastern Upper Peninsula access) - Ferry approach and port facilities for the SS Badger in Ludington - Interchange with Interstate 75 near Saginaw - Expressway junction with U.S. Route 23 and M-13 near Bay City - Eastern terminus: interchange at Pere Marquette Township

Business and alternate routes

Over the decades, business loops and alternate routings were established to serve central business districts in cities such as Manistique, Ludington, and Bay City. These designations often followed former mainline streets including alignments along Ludington waterfront and Bay City corridors and were later turned over to municipal or county control. Former business routes paralleled US 10 through commercial centers influenced by maritime trade with ports on Lake Michigan and rail connections to the Chicago, Milwaukee, St. Paul and Pacific Railroad and the Grand Trunk Western Railroad.

Future

Planned improvements for US 10 include targeted pavement rehabilitation, interchange modernization near Bay City, and safety enhancements at rural intersections coordinated by the Michigan Department of Transportation and regional planning agencies such as the Saginaw Metropolitan Area Transportation Study. Proposals have occasionally resurfaced for expanded expressway segments to better connect ferry services like the SS Badger with interstate freight routes including Interstate 94 and Interstate 69, but funding priorities tied to statewide bond issues and federal grant programs will determine scope and timing. Environmental review processes reference impacted resources such as the Manistique River watershed and coastal zones of Lake Michigan.
