US-10 rebuilding - Bay County

About this project

MDOT is investing $32.8 million to rebuild westbound US-10 from Bay City to 7 Mile Road in Bay County. This project includes rebuilding the road, as well as significant bridge improvements at 3 Mile Road, Culver Creek, and Mackinaw Road.

In 2023, crews addressed westbound US-10 and bridge work on 3 Mile Road and Culver Creek. In 2024, crews will rebuild the Mackinaw Road Bridge over US-10, widen the bridge, and add roundabouts to help reduce congestion and manage traffic flow for Mackinaw Road and the US-10/Mackinaw Road interchange.
