Message forwarded from MDOT Operations Engineer Keith Brown, P.E.:
I-75 project update. The contractor is working on northbound I-75 from the south county line up to I-475. To complete the ramps at Holly Road we will need to close and detour the ramps tomorrow night, weather permitting.
The detour for northbound I-75 traffic to Holly Road would be to stay on northbound I-75 to M-54 Dort Highway. Head north on M-54 to Grand Blanc Road. Head east on Grand Blanc Road to Saginaw Road. Take Saginaw Road south to Holly Road.
