Michigan Highway 239 is a tiny north-south connector to Indiana State Route 39, in the far southwest corner of Michigan. When the roadway carrying Indiana State Route 39 reaches the Michigan state line, Michigan Highway 239 continues the designation of the roadway as a state highway. The designation continues for about a mile and a half so it has a place to end at Interstate 94, alongside the town of New Buffalo, Michigan. That interchange, labeled "exit 1", is the northern terminus of Michigan Highway 239, though the roadway continues north, into downtown New Buffalo.
My photo for Michigan Highway 239 signage hails from the eastbound offramp, at exit 1 from Interstate 94 in Michigan. Drivers leaving Interstate 94's eastbound lanes will see that a turn to the right will put them on Michigan Highway 239. This photo was taken during a drive to Traverse City in March 2018.
