US-23 and I-75 Repair and Rebuilding Project - Emmet and Cheboygan counties

Start: April 2022    End: 2023

What Is Being Done?
The Michigan Department of Transportation (MDOT) is currently preparing to begin road and bridge repair and rebuilding work on I-75 and US-23 in the village of Mackinaw City in both Emmet and Cheboygan counties. 

I-75 will be resurfaced from Old M-108 north to the Mackinac Bridge, and the bridges over the Northwestern State Trail and Central Avenue will have maintenance work completed. 

US-23 will be rebuilt from I-75 to Huron Avenue, a project that will include replacing the bridge superstructure for southbound US-23 over I-75, eliminating the existing boulevard between Old US-31 Highway and Nicolet Street, and replacing the traffic signal at Nicolet Street.

Other work includes detour route paving, drainage improvements, tree removal, sign replacement, and new pavement markings.

How Traffic Will Be Affected
During the work on the southbound US-23 bridge over I-75, southbound US-23 traffic will be detoured on local streets, including Jamet Street, Louvigny Street, Central Avenue, and Nicolet Street. This detour will be in place for most of the construction season, from spring until fall.

Primarily, I-75 traffic will be maintained with lane closures and traffic shifts; however, at times, I-75 traffic will also be detoured using local routes.

Additional Information
MDOT will continue work in the village of Mackinaw City by rebuilding US-23 from Huron Avenue southeasterly approximately 3.3 miles to the Mill Creek Discovery Park entrance in Cheboygan County.

In 2023, the entire roadway will be reconstructed. The center left turn lane will end just northwesterly of Stimpson Road, and passing flares are planned to be built at Mackinaw Mill Creek Campground and at the Mill Creek Discovery Park Entrance. Other work includes culvert replacements, tree clearing, sign replacement, and new pavement markings.

During this work, traffic will be maintained on US-23 using traffic regulators and temporary traffic signals. Plans are currently in development and anticipated to be completed in mid-2022.
