PROJECT:                      
The Michigan Department of Transportation (MDOT) will adjust the interchange configuration of I-75/M-46 in Saginaw County. M-46 traffic will be shifted to the newly built side of M-46, and traffic will begin maneuvering through the roundabouts. This work is part of an overall $61.5 million investment to rebuild 2.4 miles of I-75 in Saginaw County, including the M-46 bridge and I-75/M-46 interchange.

TRAFFIC RESTRICTIONS:  
Drivers should expect lane closures and shifts on I-75 while signing and ramp adjustments are made.

M-46 traffic will be shifted to the new roadway and begin maneuvering through the roundabouts. I-75 traffic accessing M-46 will be directed to the south loop ramps. This configuration is expected to remain in place through the winter to accommodate removal of the original M-46 structure, and to allow crews to rebuild the permanent interchange ramps.

SAFETY BENEFITS:
This work involves rebuilding and widening I-75 from Hess Avenue to the south junction of the I-675 interchange, reducing congestion and improving safety. It will also replace the aging I-75/M-46 interchange and M-46 bridge structures, improving traffic flow and reducing potential crashes.
