MDOT Starts $7 Million Bridge Improvement Project at I-96, US-31 Interchange in Muskegon County

NORTON SHORES — The Michigan Department of Transportation (MDOT) is kicking off a $7 million project to improve the U.S. 31 bridges over Interstate 96 in Muskegon County. Construction is scheduled to begin on Monday, April 6, 2026.

The project includes comprehensive work to resurface the on and off ramps at the interchange, address structural issues with the bridges themselves, and improve overall safety for motorists traveling through this busy corridor.

Scope of Work

According to MDOT, the $7 million investment encompasses several critical components:

• Partial deck replacement on the U.S. 31 bridges over I-96
• Installation of new expansion joints to prevent cracking and water infiltration
• Substructure improvements to strengthen the bridge foundations
• Approach replacement to improve the transition between ramps and the main roadway
• Installation of new bridge railing for enhanced safety

The U.S. 31 bridges over I-96 serve as a crucial connection point for residents and businesses in Muskegon County, facilitating the movement of people and goods between the county and the broader I-96 corridor that runs from Grand Rapids to Detroit and beyond.

Why This Matters

This infrastructure investment addresses aging bridge components that have been in service for decades. The partial deck replacement will extend the life of the bridges and improve ride quality for motorists. New expansion joints help prevent water damage and structural deterioration, which are common causes of bridge degradation.

The substructure improvements will strengthen the foundations that support the bridges, ensuring they can continue to handle heavy traffic loads safely. Approach replacement improves the transition between the ramps and the main roadway, reducing the risk of accidents caused by poor road geometry.

Construction Timeline

The project is expected to proceed throughout the spring and summer construction season. MDOT will provide updates on progress and any potential impacts on traffic flow as work continues.

Impact on Travelers

The resurfacing work on the on and off ramps will require lane closures and temporary traffic shifts. MDOT will coordinate with local authorities to minimize disruptions and keep travelers informed about any changes to traffic patterns.

Drivers using this corridor should expect reduced speeds and possible delays during construction hours. MDOT recommends allowing extra travel time and checking for current traffic conditions before making trips through the area.

Part of Larger Infrastructure Investment

This Muskegon County project is one of many MDOT infrastructure investments being made across Michigan in 2026. The department continues to prioritize critical bridge and roadway improvements to keep Michigan's transportation network safe and reliable.

The I-96 corridor itself is a major transportation artery for West Michigan, connecting communities from Grand Rapids to Detroit and serving as a vital link for commerce and travel throughout the state.
