Michigan Highway 18 is a north-south highway at the base of the Lower Peninsula's "fingers", about thirty miles west of Saginaw Bay. The southern end of the highway is at US Route 10, west of Midland. From there, Michigan Highway 18 runs north through Beaverton, Gladwin, Prudenville, and Roscommon. At Roscommon, the highway jogs east before reaching its final northerly stretch. That stretch ends at Michigan Highway 72 about halfway between Grayling and Mio.
My photo of Michigan Highway 18 comes from the eastern end of its concurrency with Michigan Highway 61, in Gladwin. There, Michigan Highway 18 just come from the north to join Michigan Highway 61 westward. That concurrency only lasts for about a mile. The sign assembly shown communicates to westbound travelers on Michigan Highway 61 that Michigan Highway 18's southward travelers are also along for the ride, for the time being. This photo was taken in March 2019, during a trip around central and south-central Michigan.
