Major I-75 Resurfacing Project in Oakland County Begins in Early March

Bridge and road work along I-75 in northern Oakland County is expected to resume in early March. The Michigan Department of Transportation (NDOT) is investing approximately $160 million to resurface and repair I-75 from M-15 (Ortonville Road) to the Oakland/Genesee county line. This project includes resurfacing I-75, repairing 11 bridges, drainage improvements, culvert replacements, signs, and guardrail. Various work will be performed in different locations with different schedules throughout the 15 miles over four years. 

This year, southbound I-75 will be milled and resurfaced from M-15 to the county line, with two lanes of northbound and southbound traffic sharing the northbound side of the freeway. Bridge repairs will be performed throughout the project limits along southbound I-75. Work is expected to be completed for the year in late fall. 

In 2026, crews will remove the temporary crossovers and perform remaining miscellaneous activities.
