ST. IGNACE — Work on an overpass on the I-75 is expected to begin at the end of the month, according to the Michigan Department of Transportation.
The project will increase safety for motorists and extend the lifespan of the roadway, MDOT says.
MDOT says it is investing about $9 million to rebuild overpasses, including deck replacement, bearing replacement, substructure repairs, beam end repairs, steel cleaning and coating, and approach work on I-75 at Cheeseman Road in St. Ignace.
The project is scheduled to be completed in two years, with work on northbound I-75 to be completed in 2025 and southbound I-75 in the 2026 season.
No work will occur during winter shutdown periods, MDOT said in a news release.
The tentative start date is set for March 31, 2025, with an estimated end date of Nov. 6, 2026.
Northbound and southbound I-75 traffic will be reduced to one lane, with northbound traffic crossed over to the southbound side using temporary crossovers.
Two-way traffic will be maintained via temporary concrete barrier walls. A 12-foot lane width restriction will be in place during the project. The posted speed limit will be reduced to 60 mph; 45 mph where workers present.
Based on economic modeling, this investment is expected to directly and indirectly support 86 jobs, MDOT said.
