SOUTHWEST MICHIGAN — Construction on two Southwest Michigan highways is set to begin next Monday.

The Michigan Department of Transportation will be resurfacing 2.7 miles of M-66 from D Drive South to Glenn Cross Road in Calhoun Couty. The $547,000 project includes lengthening the southbound right-turn lane at Glenn Cross Road, joint and crack repairs, and pavement markings.

One lane of alternating traffic will remain open under flag control from Aug. 14 to Oct. 13.

MDOT Marshall Transportation Service Center Manager Mark Dionise said the project will improve safety by extending the southbound right-turn lane at Glenn Cross Road.

A new asphalt surface will improve the ride for motorists and extend the life of the road by seven to 10 years, MDOT states.
