The Michigan Department of Transportation announced on April 9 that work will resume April 16 on a $7.3 million project to stabilize the slope along M-25 near Lake Huron, south of French Line Road in Sanilac County. The effort, which began in 2025, includes slope restoration, drainage upgrades, guardrail work and pavement markings. The upcoming phase will focus on culvert improvements and is expected to continue through May 8.
This project is important for maintaining safe travel conditions and preventing further erosion along the lakeshore. According to the department, “This work to stabilize the slope from M-25 down to Lake Huron will restore the bank and prevent further erosion, prolonging the life of the roadway while preventing further loss of the shoulder and roadside into the lake.” Two-way traffic will be maintained via a single-lane closure with temporary traffic signals during construction.
The investment is projected to support approximately 61 jobs directly or indirectly through economic modeling. Work is weather dependent and could be adjusted if necessary.
