The Michigan Department of Transportation (MDOT) is allocating approximately $400,000 toward critical bridge rehabilitation on the M-123 structure spanning I-75 at exit 352. This initiative encompasses the installation of temporary supports and targeted substructure patching to ensure long-term structural integrity.
I-75 Project Details
- Location: Mackinac County, at the I-75 and M-123 (exit 352) interchange near St. Ignace
- Tentative Commencement: Monday, June 1, 2026
- Projected Completion: Tuesday, August 11, 2026
I-75 Traffic Impacts
Motorists can anticipate single-lane closures and possible delays in both directions of I-75 beneath the bridge throughout the construction period. A 12-foot width restriction will also be enforced to maintain safety and operational efficiency.
Economic and Safety Outcomes
Economic modeling indicates that this investment will directly and indirectly sustain three jobs. Upon completion, the enhancements will extend the service life of the structure while delivering measurable improvements in motorist safety.
