I-75/LaPlaisance Road Rebuilding Project - Monroe County

Start: March 2021     End: November 2022

What Is Being Done?
The Michigan Department of Transportation (MDOT) will be rebuilding the LaPlaisance Road bridge over I-75, along with the nearby and on and off ramps. 

How Traffic Will Be Affected
Lane closures and detours will be announced closer to the beginning of work.

Safety Benefit
The new bridge will be a part of the redesigned and rebuilt interchange that will include new roundabouts on each side of the bridge. These roundabouts will allow traffic to operate more smoothly and efficiently, and increase safety with fewer conflict points. For more information about roundabouts, go to
