GAYLORD, Mich. - From 8 p.m. Tuesday, July 26, through 6 a.m. Thursday, July 28, I-75 in Mackinaw City will be closed while new beams for the southbound US-23 bridge are installed.
During this closure, northbound I-75 traffic will be detoured on Nicolet Street (Exit 337) to Jamet Street (Exit 339). Southbound traffic will be detoured on Jamet Street (Exit 339), Louvigny Street, Central Avenue, and Nicolet Street to Exit 337. This detour for I-75 through-traffic will be in place until 6 a.m. Thursday, July 28. Remaining work on the bridge will be done with single-lane closures on I-75.
The southbound I-75 exit ramp to US-23 (Exit 338) in Mackinaw City has been closed since May 31 as contractors began removing and replacing the ramp’s pavement on both ends of the bridge deck, part of a larger project this season to rebuild and repave sections of the highway. Southbound drivers planning to stop in Mackinaw City or head east on US-23 toward Cheboygan will be directed to take Exit 339 and detour on Jamet Street, Louvigny Street, Central Avenue, and Nicolet Street. This detour for Mackinaw City and US-23 traffic will be in place through October.
The Michigan Department of Transportation 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 (Nicolet Street/Mackinaw Highway) (Exit 337) to the Mackinac Bridge, as well as replace the southbound US-23 exit ramp bridge beams and deck over I-75. Much of the I-75 road work will require shoulder or single-lane closures with traffic shifts.
The project also includes rebuilding the I-75 ramps at Jamet Street (Exit 339) and Nicolet Street (Exit 338), upgrades to the I-75 bridges over the D&M Railroad and Central Avenue, and reconfiguring the US-23/Nicolet Street intersection for a new traffic signal installation. The project is scheduled to be completed by mid-November.
Based on economic modeling, this investment is expected to directly and indirectly support 155 jobs. Details on the project are available on the project website.Media Contact:
