M-24 marker

M-24 is a north–south state trunkline highway in the U.S. state of Michigan that extends 75.691 miles (121.813 km) through Southeast Michigan and The Thumb, 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.

M-24 begins a hundred feet south of an overpass that is part of a double trumpet interchange with I-75 in Auburn Hills. The interchange also connects with an entrance into The Palace of Auburn Hills, home of the NBA's Detroit Pistons, and a variety of electronic signs are contained in the area to indicate the status of access to the entrance. The roadway is a continuation of Business Loop I-75 (BL I-75) that travels through Pontiac. This section of the highway dedicated to William Davidson, former owner of the Pistons, in legislation signed by Michigan Governor Rick Snyder in May 2011.
