Final Lane, Exit Closures Expected as I-75 Work Nears Completion

A major $160 million project to resurface and repair I-75 from M-15 (Ortonville Road) to the Oakland and Genesee County line is nearing completion. As the work wraps up, crews are focused on final lane and exit closures and on removing traffic control devices.

From Friday, Oct. 31, through Monday, Nov. 3, southbound I-75 Exit 101 to Grange Hall Road will be closed. Additionally, the northbound M-15 entrance ramp to southbound I-75 will be closed, and I-75 will have two lanes closed between Baldwin Road and Clarkston Road.

Beginning Monday, Nov. 3, and running through early December, southbound I-75 traffic will switch onto the rebuilt southbound side. Northbound I-75 will be reduced to one lane from Baldwin Road to Clarkston Road for about three weeks to remove the 15 miles of temporary barrier wall. After crews remove the wall, northbound traffic will reopen to two lanes.

Finally, a series of ramp closures through early December will affect several connections, including the following:

According to an Oakland County Times report, major construction is expected to wrap up by early December. Remaining work will stretch into 2026 to remove temporary crossovers, apply final pavement markings and rumble strips, and complete landscaping.

The construction work is funded by Gov. Gretchen Whitmer's Rebuilding Michigan program, which aims to deliver longer-lasting highway and bridge improvements with broader economic benefits.

The project encompasses resurfacing I-75, repairing 11 bridges, improving drainage, replacing culverts, and upgrading signs and guardrails across a 15-mile section over four years. Based on economic modeling, the state's investment for the project has directly and indirectly supported 1,936 jobs, according to the Oakland County Times.
