M-24 (Michigan Highway)
M-24 is a state trunkline highway in the U.S. state of Michigan that extends 74.300 miles (119.574 km) through Southeast Michigan, from northeast Auburn Hills to Unionville. It starts at an interchange with Interstate 75 (I-75) and ends where it merges with M-25. While the M-24 designation is similar to that of US Highway 24 (US 24) which has a northern terminus located only a few miles from the southern terminus of M-24, M-24 was never part of US 24.
The first M-24 in Michigan was replaced by M-20 when US 10 replaced the original M-20 in 1926. A 1936 bypass of downtown Pontiac resulted in the creation of M-24A which later became BUS M-24 in 1940. An extension in 1997 moved the northern end of M-24 northward from Caro to Unionville, replacing a section of M-138 in the process.
