I-75 Lane, Ramp Closures, Detours for Work Beginning March 17 in Michigan

The Michigan Department of Transportation (MDOT) reports that bridge and road work along I-75 in northern Oakland County continues as part of $160 million project 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.  

Pavement marking replacement and stage setup for construction requires lane closures. A reminder, work is highly weather-dependent and the closure timeframe may be adjusted for favorable weather. 

5:00 am Monday, March 17 – 9:00 pm Friday, March 21

Northbound I-75 will have two lanes open from Clarkston Road in Oakland County to Baldwin Road in Genesee County. 

Daily closures 6:00 am – 3:00 pm Monday, March 17 – Monday, March 24

• Northbound I-75 will have only one lane open from Clarkston Road to Baldwin Road.
• The northbound I-75 ramps will be closed intermittently at the following interchanges:
  • M-15

  • Holly Road

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