A major highway construction project is underway in Saginaw right now.
The construction project, which is scheduled to end by late November, will cause some major shifts in traffic on I-75 and I-675.
Northbound I-75 is being detoured to northbound I-675. This is so southbound I-75 traffic can move to the northbound I-75 lanes.
Crews are also going to close southbound I-675 south of exit 2. Exit 2, which leads to downtown Saginaw, will remain open.
Commercial and passenger traffic will each be detoured using different routes when traveling southbound on I-675.
All commercial traffic will be detoured via northbound M-13, eastbound M-81, southbound Towerline Road, and westbound M-46.
For passenger traffic that still wishes to travel south via I-675, the diversion will be southbound M-13, then eastbound M-46.
The Michigan Department of Transportation (MDOT) also says that:
The M-81 ramps to I-75 will be closed with traffic rerouted east to Towerline Road, then south to westbound M-46. The southbound I-75 ramp to M-81 will be open.
The M-13 ramps to I-75 will be closed. Commercial vehicles will be detoured via southbound M-13, eastbound M-81, southbound Towerline Road, and westbound M-46. Passenger traffic will be rerouted to southbound M-13, then to eastbound M-46.
The southbound I-675 on ramps at M-58 (State Street), Second Street, Sixth Street, and Veterans Memorial Park will be closed.
