Michigan Highway 77 is a north-south highway in the middle of the Upper Peninsula's eastern half. The southern end of Michigan Highway 77 is at US Route 2, the highway across the southern part of the Upper Peninsula. The northern end is in Grand Marais, not at any other marked route; the route wasn't going to continue any further northward, as Grand Marais is on the southern shore of Lake Superior! Between Michigan Highway 77's two endpoints, the route only passes through the tiny towns of Germfask and Seney. It intersects US Route 2 at the south end and Michigan Highway 28 at Seney; outside of these two routes, Michigan Highway 77 meets no others.
My photo of Michigan Highway 77 comes from Seney, where Michigan Highway 77 has a short concurrency with Michigan Highway 28. Soon after Michigan Highway 77 turns from southerly to westerly along Michigan Highway 28, Michigan Highway 77 seeks to turn away again to continue heading south. The signage depicted tells westbound travelers moving along the concurrency that Michigan Highway 77 is about to split away to continue going south. This photo was taken in August 2020 along a trip to the Porcupine Mountains, Pictured Rocks, Mackinac Island, and Traverse City (I was between the first two destinations when taking this photo).
