Arch Rock Plaza Closure - Mackinac State Historic Parks | Mackinac State Historic Parks

Arch Rock Plaza Closure

Roads to Arch Rock will be closed at Leslie Avenue and Huron Road. Roads in red will have occasional vehicle traffic Septhroughout the closure.

**May 10, 2024 Update – The Arch Rock Plaza will be open today, May 10, beginning at 1:00 p.m.***

The Arch Rock Plaza is closed starting Monday, September 11, as construction of the $7.5 million Milliken Nature Center begins at the area.  The area will remain closed through at least April of 2024.

The Arch Rock Plaza will be closed to all traffic – including carriages, bicycles, and pedestrians. Guests will be able to view Arch Rock from M-185, the shoreline road that circles Mackinac Island, and access the Arch Rock viewing platform via the Spring Trail stairway. This path is also subject to closure.

Arch Rock Area Closures. Roads in red will have occasional vehicle traffic but remain open to guests.

The plaza will be closed at the intersection of Rifle Range Road and Leslie Avenue and again at the intersection of Arch Rock Road and Huron Road. The Arch Rock Bicycle Trail and Botanical Trail will dead end before the hill leading to Arch Rock.

Guests will still be able to make a loop near the Arch Rock area by backtracking to Winnebago Trail, which runs from Huron Road to Rifle Range Road. It crosses Pottawatomie Road, Arch Rock Road, the Arch Rock Bicycle Trail, Rock Trail, and ends at the intersection of Rifle Range and Sugar Loaf Roads.

In addition to the work at the Arch Rock Plaza, occasional truck traffic from British Landing – on State, Garrison, and Rifle Range Roads – will happen. Guests are encouraged to stay to the right side of the road and slow down to allow trucks to pass. Trucks will also occasionally head down British Landing Road to the Waste Management Facility, located across from Wawashkamo Golf Club.

During construction a new drain field will be added to the Arch Rock area, and the out-of-date restroom structure will be demolished. The Milliken Nature Center, named for Michigan Governor William Milliken, will include modern restrooms, a nature center, and space for guests at Arch Rock to relax.

During this time Mackinac Island Carriage Tours, private livery tours, drive-yourself carriages, and saddle horses will have alternate routes that avoid Arch Rock. Contact Jack’s Livery Stable or Mackinac Island Carriage Tours for more information.

The Milliken Nature Center is slated to open in May, 2024. Site groundbreaking took place September 1.
