M-185 Lakeshore Loop
M-185
The only state highway in America where motor vehicles are banned. It runs about 13 km around the island along the lakeshore, and a bicycle ride of 1 to 2 hours takes you all the way around.
M-185 is a Michigan state highway that circles Mackinac Island. It is about 13 km long, and because cars are banned on the island, it is the only state route in the United States with no cars. The road hugs the shore, with the clear waters of Lake Huron and the distant Mackinac Bridge on one side, and limestone cliffs and forest on the other. Sights along the way include the Arch Rock staircase, the British landing site and the Devil's Kitchen rock formation. The road is flat. Cycling takes about 1 to 1.5 hours, and walking takes about 4 hours. You can rent bicycles, tandems or electric-assist bikes on Main Street, and you must follow the local rules. Rest stops and restrooms are spaced along the route. It is recommended to ride counterclockwise and carry plenty of water.
