US Highway 2 (US 2) is a component of the United States Numbered Highway System that connects Everett, Washington, to the Upper Peninsula (UP) of the US state of Michigan, with a separate segment that runs from Rouses Point, New York, to Houlton, Maine. In Michigan, the highway runs through the UP in two segments as a part of the state trunkline highway system, entering the state at Ironwood and ending at St. Ignace; in between, US 2 briefly traverses the state of Wisconsin. As one of the major transportation arteries in the UP, US 2 is a major conduit for traffic through the state and neighboring northern Midwest states. Two sections of the roadway are included as part of the Great Lakes Circle Tours, and other segments are listed as state-designated Pure Michigan Byways. There are several memorial highway designations and historic bridges along US 2 that date to the 1910s and 1920s. The highway runs through rural sections of the UP, passing through two national and two state forests in the process.

The US 2/US 41 expressway north of Gladstone was, until 2017, the only non-freeway section of highway in the UP with a speed limit higher than 55 mph (89 km/h).

Michigan State Trunkline Highway System
The State Trunkline Highway System consists of all the state highways in Michigan, including those designated as Interstate, United States Numbered, or State Trunkline highways. In their abbreviated format, these classifications are applied to highway numbers with an I-, US, or M- prefix, respectively. The system is maintained by the Michigan Department of Transportation (MDOT) and comprises 9,669 miles (15,561 km) of trunklines in all 83 counties of the state on both the Upper and Lower peninsulas, which are linked by the Mackinac Bridge. Components of the system range in scale from 10-lane urban freeways with local-express lanes to two-lane rural undivided highways to a non-motorized highway on Mackinac Island where cars are forbidden. The longest highway is nearly 400 miles (640 km) long, while the shortest is about three-quarters of a mile. Some roads are unsigned highways, lacking signage to indicate their maintenance by MDOT; these may be remnants of highways that are still under state control whose designations were decommissioned or roadway segments left over from realignment projects.
