MDOT to Start I-75 Sign, Guardrail Upgrades

Michigan Department of Transportation (MDOT) will soon start upgrades along Interstate 75 north of St. Ignace to south of Sault Ste. Marie, the department announced Wednesday.

The work includes about 57 miles of freeway sign upgrades, overhead sign structures, guardrail upgrades and reflective roadside delineators.

Crews are expected to start on the project Tuesday, April 19. It is expected to continue through Oct. 14.

All work will be done during daylight hours, and at least one lane will be open at all times northbound and southbound. Drivers may see intermittent shoulder or single-lane closures.

The project will improve sign visibility for drivers. Upgraded guardrails and added delineators will increase safety, according to MDOT.
