Mackinac Island is home to State Route M-185.  It is a state highway that is 8.2 miles long and circles Mackinac Island.  It is impossible to visit Mackinac Island without stepping foot on M-185.  It follows the entire shoreline of the Island and offers scenic views of the straits that divide the Upper and the Lower peninsulas of Michigan and Lakes Huron and Lake Michigan. It has no connection to any other Michigan state highways—as it is on an island—and is accessible only by passenger ferry.

On the island a portion of the highway is called Main Street, located within the built-up area on the island's southeast quadrant, and Lake Shore Road elsewhere. M-185 passes by several important sites within Mackinac Island State Park, including Fort Mackinac, Arch Rock, British Landing, and Devil's Kitchen.


Lake Shore Road carries the highway next to the Lake Huron shoreline, running between the water's edge and woodlands outside the downtown area.


According to the Michigan Department of Transportation (MDOT), M-185 is "the only state highway in the nation where motor vehicles are banned". Traffic on it is by foot, on horse, by horse-drawn vehicle, or by bicycle. Restrictions on automobiles date back to the 1890s, and since the ban, only a few vehicles have been permitted on the island other than the city's emergency vehicles.


The highway was built during the first decade of the 20th century by the state and designated as a state highway in 1933. The highway was paved in the 1950s, and portions were rebuilt to deal with shoreline erosion in the 1980s. Until an accident in 2005, it was the only state highway without any automobile accidents.
