M-185, the state highway that encircles Mackinac Island, will be partially closed for the 2021 summer season. Construction crews will be paving portions of the road that were damaged due to erosion stemming from high water levels.
M-185 will be closed from Arch Rock to British Landing on the north side of the island, a section totaling about four miles. Barricades and signs will mark the closed portions of the road. Guests who ride to Arch Rock will have to turn around and ride back toward town. At British Landing, riders can turn up British Landing Road and ride toward the center of the island.
People found going around the barricades can be issued tickets and fines.
Mackinac State Historic Parks thanks visitors and residents of Mackinac Island for their patience while the road has been under repair.
