Avoid This Major I-75 Detour If You’re Headed Up North

If you're headed "up north" in Michigan, there's one route you'll want to avoid.

MDOT Construction Projects 2025

If you typically travel along I-75 and take the Zilwaukee Bridge up north, you'll want to take a detour. At least not for the rest of this summer.

Michigan Department of Transportation (MDOT) crews have begun work on the northbound lanes on the Zilwaukee bridge.

When Will the Zilwaukee Bridge Reopen?

Work on the Zilwaukee bridge first began earlier this year on the southbound lanes. That portion of the project began in April and has wrapped up, with the crews having shifted to the northbound portion of the bridge work on Monday, August 4.

Expect the northbound lanes between Kochville and Wadsworth roads to be closed until mid-November.

Here’s What the Detour Looks Like

If you want to know specifics about the traffic restrictions, here's what MDOT has to say:

Northbound I-75 will be closed and detoured to northbound I-675 from the I-75/I-675 interchange south of Wadsworth Road to the northbound I-675 junction north of Kochville Road.

The westbound M-81 ramp to northbound I-75 will be closed during this work. Traffic will be detoured via southbound I-75 to I-675 northbound near Wadsworth Road.

The southbound M-13 ramp to northbound I-75, as well as the northbound I-75 ramp to northbound M-13 will be closed. Traffic for the southbound M-13 ramp to northbound I-75 will be detoured via southbound I-75 to northbound I-675. Traffic for the I-75 ramp to northbound M-13 will be detoured via westbound M-81 to westbound M-13.

The southbound I-675 ramp to northbound I-75 also will be closed. Traffic will be detoured via southbound I-675, M-46 to northbound I-75.

Besides being summertime in Michigan, it's also construction season, so this isn't the only road work going on. There's roadwork going on locally and statewide just about everywhere you look. But hey, at least they're fixing "the damn roads".
