MDOT: US-23, I-75 Project Begins Monday
Construction on US-23 and I-75 in Mackinaw City is starting on Monday.
The Michigan Department of Transportation (MDOT) is investing $12.3 million to rebuild and resurface US-23 from I-75 to east of South Huron Avenue and I-75 from Old M-108 (Exit 337- Nicolet Street/Mackinaw Highway) to the Mackinac Bridge.
They are also replacing the southbound US-23 exit ramp beams and deck over I-75, rebuilding I-75 ramps at Jamet Street (Exit 339) and Nicolet Street (Exit 338), upgrading the I-75 bridges over the D&M Railroad and Central Avenue and reconfiguring the US-23/Nicolet Street intersection.
MDOT states much of the construction will require shoulder or single-lane closures with traffic shifts. Work on the US-23 exit ramp bridge will require a detour on city streets from June through the end of Oct.
They say these upgrades will provide a safer and smoother driving surface, as well as will improve traffic flow at the US-23/Nicolet Street intersection and will extend service lines for five bridges as well as the road.
Construction is scheduled to be completed by mid-Nov.
