Update: Westbound US-10 ramps reopening postponed to Nov. 6 in Bay County

BAY CITY, Mich. - The Michigan Department of Transportation (MDOT) will begin shifting traffic back to the westbound lanes and reopening the westbound US-10/Mackinaw Road interchange ramps on US-10 on Monday, Nov. 6.

This work is part of an overall $32.8 million investment to rebuild westbound US-10 from 7 Mile Road to Bay City. The project includes bridge maintenance at Three 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, as well as replacing the current traffic signals.
