M-86 (Michigan highway)

M-86 is an east–west state trunkline highway in the US state of Michigan in the southern portion of the Lower Peninsula. The highway starts at Business US Highway 131 (Bus. US 131) and M-60 in Three Rivers and ends at US Highway 12 (US 12) near Coldwater. In between, it crosses farm country and runs along a section of the Prairie River. Following a highway originally numbered M-7, the roadway was renumbered M-86 in 1940. It has been a part of the state highway system at least since 1927. Two other roadways carried the M-86 designation in the 1920s. Two bridges along the road are eligible for inclusion on the National Register of Historic Places (NRHP).
