Project to upgrade I-75 near Oakland-Genesee border to begin in May

A three-year project to upgrade Interstate 75 between Ortonville Road and the Genesee County-Oakland County line is scheduled to begin in May, state officials said Friday.

Under the $160 million project, crews for the Michigan Department of Transportation will resurface three lanes of the freeway in both directions, reconstruct shoulders, replace culverts, signs and guardrails as well as improve 11 bridges in the 15-mile stretch. Work on the bridges will include deck patching, some full deck replacements, painting, and repairs to both substructures repairs and superstructures.

In May, crews will build temporary crossovers on northbound and southbound I-75 as well as make repairs to the pavement and conduct bridge work, MDOT said. The work will be performed through late fall.

Next year, crews will mill and resurface northbound I-75 between Ortonville Road and the county line. During the work, two lanes of both directions will share the existing southbound roadway, according to the agency.

In 2025, the same type of work will be done on the southbound lanes of the freeway with traffic sharing the existing northbound roadway, officials said.

Lastly, the temporary crossovers and remaining miscellaneous work will be removed in 2026, MDOT said.

This isn't the only I-75 construction work. Farther south, MDOT is continuing a more than decade-long project of rebuilding the freeway north of 8 Mile Road.

Construction crews are working on rebuilding a stretch of I-75 between 13 Mile Road and I-696. The work is focusing on building new southbound lanes.

The work has meant funneling two lanes of northbound and southbound traffic through the three-mile section of rebuilding.
