SAWYER, Mich. (AP) — Visitors to Michigan’s Warren Dunes State Park may see intermittent closures through the spring and summer as two renovation projects get underway at the area along the eastern shore of Lake Michigan.

Crews have already started a more than $1 million project to renovate Red Arrow Highway, which serves as the main entrance to the sand dunes and lakeshore beaches in Berrien County.

The Michigan Department of Transportation is overseeing the road repairs, and a lane addition to reduce traffic buildup. The efforts should be completed by May 20.

A more than $2 million project will also begin this month to replace toilets and bathhouse buildings in the park’s day-use area. Plans call for making more room for additional food truck vendors.

The upgrades should be finished by November.
