The Michigan Department of Transportation (MDOT) will begin the next phase of an overall $26.4 million investment to improve M-46 in Sanilac County next Monday, February 17.
This phase of the two-year project will include resurfacing M-46 from the Sandusky east city limit to the Carsonville west village limit and replacing the M-46 bridge over the Black River.
The work, which is estimated to end in October, will result in M-46 being closed in both directions. Traffic will be detoured from Ruth Road to Forester Road and Maple Grove Road. The carpool lot on M-46 east of Ruth Road will be closed during this work.
Work in 2024 included rebuilding M-46 in the city of Sandusky, replacing storm sewer, upgrading traffic signals, replacing curbs, upgrading sidewalks, and safety improvements, as well as improving M-19 in the city of Sandusky.
