BAY COUNTY (WJRT) (4/5/2019) - Traveling through the Bay City area on I-75 will take longer this summer, as the Michigan Department of Transportation embarks on a $29.5 million construction project.
Beginning Monday, MDOT is rebuilding 4.2 miles of the freeway in both directions between North Union and Beaver roads. The project also includes work on 11 bridges.
The decking on the Wilder Road, Mackinaw Road and Chip Road bridges over I-75 all will be completely replaced this summer.
Mackinaw and Chip roads already are closed to traffic. Demolition of those bridges is scheduled for April 15 to 18 during overnight hours, which will require full closures of I-75.
Lane closures are scheduled to begin next week along I-75.
MDOT says traffic will be maintained in both directions along I-75 with traffic shifts and a moveable barrier that will accommodate an additional lane of travel in one direction during peak times, especially during busy weekends.
Beginning in mid-May, the ramps at I-75 and Beaver Road will be closed.
When the Mackinaw Road and Chip Road bridges are complete, Wilder Road will close over I-75 for deck replacement.
Completion of the entire project is scheduled in October depending on weather.
