M-20 is a state trunkline highway in the US state of Michigan that runs from New Era to Midland. It crosses through rural Lower Peninsula forest land between the two ends. The highway serves the college towns of Big Rapids and Mt. Pleasant, home of the main campuses of Ferris State University and Central Michigan University, both located near the trunkline.
The original July 1919 routing took M-20 farther north along a corridor now used by US Highway 10 (US 10). The M-20 designation was shifted south to the current corridor in 1926. The eastern end was truncated from Bay City to Midland in 1960, following the opening of a freeway between the two cities. The western end was rerouted from Muskegon to New Era in 1969.
