- from our Affiliates
M-185 is the 8 mile long highway that circles Mackinac Island at the shoreline; it was built in 1933 and is probably the only US highway on which motorized traffic is banned! Only pedestrians, bicycles, horses and horse-drawn carriages are allowed! Many tourists rent bicycles on the island and ride it around!
