M-185 Closed

M-185, the road that encircles Mackinac Island, is temporarily closed to repair erosion from high water levels. The road is closed from British Landing to Arch Rock.

For your safety, please stay off the roadway. The Mackinac Island State Park offers many miles of open trails and roads.  Please consult the map below. This project is under the direction of the Michigan Department of Transportation with assistance from Mackinac State Historic Parks.

Thank you for your patience.
