The Michigan Department of Transportation (MDOT) reports that, as part of the I-75 project between M-15 (Ortonville Road) and the Oakland/Genesee county line, a traffic switch will occur for crews to begin removal of traffic control devices. Once northbound I-75 is moved back to the northbound lanes, crews will begin removal of the barrier wall on southbound I-75. Once all the traffic control devices are removed from southbound I-75, both bounds will be placed back in the normal configuration with 3 lanes in each direction until late winter 2025 when construction begins again with project completion in late 2026. 

From 5:00 a.m. – 7:00 p.m. October 27, northbound I-75 from M-15 to the Oakland/Genesee county line will be reduced to one lane.  

The following ramps will have intermittent closures as crews work to restripe the roadway:

  • The northbound I-75 ramp to M-15 (exit 91).
  • The northbound I-75 ramp to Dixie Highway (exit 93).
  • The northbound I-75 ramp to East Holly Road (exit 98).
  • Grange Hall Road entrance ramp to northbound I-75 (MM 101).
  • The northbound I-75 ramp to Saginaw Road (exit 106). 

The expected completion date for this portion of the project is December with all ramps and mainline I-75 fully open.
