Westbound US-10 detour in Bay County starts May 12

BAY CITY, Mich. - The Michigan Department of Transportation (MDOT) will begin the first phase of detouring westbound US-10 traffic to accommodate ongoing work beginning Friday, May 12. This work is part of an overall $32.8 million investment to rebuild westbound US-10 from 7 Mile Road to the city of Bay City.

This project includes bridge maintenance at 3 Mile Road, replacing a culvert at Culver Creek, and replacing the Mackinaw Road overpass in May 2024 with the addition of two roundabouts to mitigate congestion, and replacing the current traffic signals.


Westbound US-10

Closest city:
Bay City

Start date:
Friday, May 11, 2023

Estimated detour end date:
July 2023

Estimated project end date:
November 2024

Traffic restrictions:
Beginning Friday, May 12, westbound US-10 traffic will be detoured from Bay City to the US-10/I-75 interchange via M-13, M-84, and northbound I-75.

This detour is expected in place through the end of June.

The single-lane closure on eastbound and westbound US-10 at 3 Mile Road will remain in place through approximately June 29. Crews expect to close the 3 Mile Road bridge to begin work later this spring. That closure will be announced in advance of its start and will remain in place until all bridge repairs are complete, likely reopening just ahead of the Labor Day holiday weekend.

Jobs numbers:
Based on economic modeling, this investment is expected to directly and indirectly support nearly 397 jobs.

Safety benefit:
This project is intended to improve the pavement conditions of westbound US-10 and address important bridge repairs to ensure operations and safety of the road. This phase of detouring will allow the contractor to safely remove the westbound US-10 roadbed.
