PROJECT:                          
The Michigan Department of Transportation (MDOT) will invest $61.5 million to rebuild 2.4 miles of I-75 from Hess Avenue to I-675 in Saginaw County. Work also includes rebuilding the I-75/M-46 interchange and replacing the M-46 bridge over I-75 and the LSRC Railroad.

TRAFFIC RESTRICTIONS:  
Beginning March 23, drivers should expect single-lane and shoulder closures on I-75 and the I-75/M-46 interchange ramps to accommodate tree clearing and other staging of the work zone.

Beginning April 1, motorists should expect single-lane closures on M-46. By May 2, M-46 will be reduced to one lane in each direction maintained on the westbound M-46 lanes while work begins to replace the M-46 bridge. During this phase of construction, the south loop ramps of the I-75/M-46 interchange will be closed to traffic, with motorists detoured to the north loop ramps. Those ramps will be maintained with temporary signals to help reduce congestion.

Additional traffic restrictions will be required as construction continues. Those impacts and lane configurations will be released ahead of their start.

SAFETY IMPROVEMENTS:
This work will rebuild and widen 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.
