M-100 is a north–south state trunkline highway in the central region of the U.S. state of Michigan. It runs between Potterville and Grand Ledge, connecting Interstate 69 (I-69) and Interstate 96 (I-96) west of the state capitol, Lansing.

The highway was previously a section of M-16. After M-16 was realigned, M-100 was created by 1927. Three extensions in the 1930s, 1950s and 1990s resulted in the current highway routing.

Route description

M-100 starts at exit 66 on Interstate 69 (I-69) in Potterville. The highway runs north along Hartel Road, intersecting Lansing Road, the former route of US Highway 27 (US 27) south of downtown. Hartel Road runs due north from Potterville to Grand Ledge. North of M-43/Saginaw Highway, M-100 follows Clinton Street, jogging northwest along Jefferson Street north of Willow Highway. Crossing the Grand River on Bridge Street, M-100 returns to Clinton Street north of the river. North of town, the roadway is once again known as Hartel Road before changing to Wright Road near the Abrams Municipal Airport. North of Grand River Highway, which is the former route of US 16, M-100 meets I-96 and ends. Wright Road continues to the north of the interchange.^[3]

History

M-100 was created by 1927 when M-16 was rerouted directly between Lansing and Eagle.^[1] M-100 started at M-39 in Grand Ledge and ran north to M-16 in Eagle. The highway was extended southward in 1932 to end at US 27/M-78 in Potterville.^[4][5] The northern end was extended to meet the US 16 (now I-96) freeway in 1958.^[6] The south was similarly extended in 1991 with the completion of the I-69/US 27 freeway south of Potterville.^[7]
