M-77 is a state trunkline highway in the Upper Peninsula (UP) of the US state of Michigan. It starts at US Highway 2 (US 2) near Blaney Park north of Lake Michigan. The highway borders the eastern edge of the Seney National Wildlife Refuge and passes through the community of Germfask. At Seney, it overlaps M-28 to cross the Fox River before returning northward. The northern half has been designated as a Scenic Spur of the Lake Superior Circle Tour. M-77 runs along the eastern end of the Pictured Rocks National Lakeshore and terminates in Grand Marais north of H-58 near Lake Superior. Originally designated by 1919, the highway has not been changed much in its history. By the late 1950s, the highway was paved, completing the modern M-77 highway.

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.
