It is the fourth-shortest state highway in the system, and it serves as a connector route between M-18 and M-55 just east of Prudenville. The current roadway was built and designated as M-157 in the 1930s.

M-157 was originally designated in 1931 as a connector route between M-55 and US 27 (present-day M-18). Just a year later, that version was decommissioned, and the road obliterated. A new alignment, the present-day routing of M-157, was then commissioned just to the east.
