The Michigan Department of Transportation project is scheduled to be completed in early November.
Work includes asphalt resurfacing, concrete pavement repairs, shoulder upgrades and intersection improvements at 76th, 72nd, 64th, 56th, 48th, New Holland, 40th and 37th avenues. Indirect left — or “Michigan left” — turns will be constructed at these intersections to increase safety and improve traffic flow, MDOT officials said.
Other improvements will include corridor safety/geometric upgrades, drainage upgrades and pavement marking upgrades, and new traffic signals at 40th and 48th avenues.
One lane of traffic will be maintained in each direction on eastbound M-121 while work is completed on westbound M-121, MDOT said. A partial road closure will be in place while the eastbound lanes and the eastbound bridge over the Macatawa River are reconstructed.
Through-traffic will be detoured to 32nd Avenue and Interstate 196. Local traffic will have access to M-121 throughout the project.
