Kalamazoo County Drivers Brace for Summer Construction Headaches on Major Highway Interchange
*KALAMAZOO, MI* — Michigan Department of Transportation and Allegan County contractor Milbocker & Sons have kicked off a massive $13.4 million road improvement project at the I-94 and U.S. 131 interchange in Kalamazoo County, setting the stage for summer traffic backups and lane closures that drivers will have to endure through September.
The project, which began on March 2, will add a new auxiliary lane to help manage traffic flow between westbound I-94 and northbound U.S. 131, but it comes with a price tag in convenience for local commuters.
"Lane and ramp closures on US-131 and I-94, that's going to cause a headache for folks over the summer," said Nick Schirripa, spokesperson for MDOT. "But we're going to get in and get it done and get out as quickly as we can."
What Is an Auxiliary Lane and Why Does It Matter?
The construction aims to add what officials call an "auxiliary lane" — a temporary lane that connects an entrance ramp to the next exit ramp. This provides drivers with extra distance to accelerate, decelerate, or weave safely before merging into high-speed through-traffic lanes.
"It is not a traffic lane, it doesn't continue on, it doesn't make northbound US-131 a true three lane freeway there, just in the northbound side, it is one lane that essentially connects two exits," Schirripa explained.
The new auxiliary lane will allow drivers to transition more safely from westbound I-94 onto northbound U.S. 131 between the I-94 and Stadium Drive exits, reducing the risk of dangerous last-minute merges.
Ramp Widening and Traffic Impacts
To accommodate the new auxiliary lane, MDOT will also be widening the westbound I-94 ramp to northbound U.S. 131. This work will require significant construction activity, including potential lane closures and ramp shutdowns.
"We're going to ask you to bear with us for those couple weeks while we get through it," Schirripa said. "But by the end of the project, by the time school's out and the summer gets going, you should see a smoother commute."
The project is expected to be completed by September 2026, meaning Kalamazoo County residents and commuters will face the inconvenience throughout the summer travel season.
Construction Details and Timeline
The $13.4 million project involves:
- Adding a new auxiliary lane on the northbound U.S. 131 side
- Widening the westbound I-94 ramp to northbound U.S. 131
- Lane and ramp closures on U.S. 131 and I-94
- Various improvements to the interchange infrastructure
Crews will have to close one or more ramps periodically to complete the work, and there will be periods where travel options are limited.
"We're going to have to close a ramp or two to do work on them, and there will be periods where something is closed," Schirripa warned.
Why This Project Matters for Kalamazoo County
The I-94 and U.S. 131 interchange is one of the most heavily traveled junctions in Kalamazoo County, handling thousands of vehicles daily. The current configuration forces drivers to merge directly into high-speed lanes with limited sightlines and acceleration room.
The auxiliary lane addition will provide a buffer zone, giving drivers more time and distance to safely transition between the highways. This should reduce traffic congestion and improve safety at this critical intersection.
Summer Commuters Face the Brunt
With construction lasting through September, the project will coincide with summer vacation travel, increased commuter traffic, and the annual surge of tourists visiting Southwest Michigan.
"It's going to cause a headache for folks over the summer," Schirripa acknowledged. "But we're going to get in and get it done and get out as quickly as we can."
MDOT and Milbocker & Sons are working around the clock to complete the project as efficiently as possible, but drivers should expect ongoing disruptions to their commutes on the I-94 and U.S. 131 corridor.
What Drivers Should Expect
As construction progresses, drivers will encounter:
- Intermittent lane closures on both I-94 and U.S. 131
- Temporary ramp shutdowns
- Reduced traffic capacity at the interchange
- Potential delays during peak commute hours
The Kalamazoo County Road Commission and MDOT are working to coordinate with local businesses and residents to minimize the impact of the construction.
The Bottom Line
While the $13.4 million investment will improve traffic flow and safety at the I-94/U.S. 131 interchange, Kalamazoo County drivers will have to endure summer construction headaches. The project is necessary to modernize one of the region's most critical highway intersections, but it comes with a temporary cost in convenience and time.
By September, when construction wraps up, the improved infrastructure should provide smoother, safer travel for thousands of daily commuters. Until then, residents are encouraged to plan ahead, allow extra travel time, and stay informed about construction updates through MDOT's website and local news sources.
