M-136 is a state trunkline highway located in the southwestern portion of the Lower Peninsula of Michigan. It exists entirely within Mason County. The highway runs for approximately 12 miles (19 km), connecting U.S. Highway 31 (US 31) near Amber Township with M-116 south of Ludington State Park. M-136 provides access to several recreational areas and smaller communities within the county. It is primarily a two-lane road. The highway designation was first applied in the late 1930s and has remained largely unchanged since then.
