The Michigan Department of Transportation (MDOT) is investing about $800,000 for bridge preventive maintenance, including substructure patching, temporary supports and substructure surface sealer, on the M-134 overpass at I-75, Mackinac County.

Work will begin Monday, July 29 and is estimated to end November 1. Work will require single-lane closures on northbound and southbound I-75. One lane of traffic will be open in each direction utilizing temporary concrete barrier wall. A 12-foot lane width restriction will be in place during the project.
