Traffic impacts

All traffic control has been removed from the project site. Final work continues with little to no disruption to traffic.

Reminder: Southbound Highway 52 traffic now uses the new flyover ramp to access eastbound I-90. Stay in the right lane on southbound Highway 52 and follow the signs to the flyover ramp for eastbound I-90.

About this project

Summary of work

Construction is scheduled 2024-2026 to make changes to the I-90/Highway 52 interchange to improve safety and reduce delays.

• 2024: Constructed temporary crossovers and begin new ramps and loops
• 2025: Constructed new eastbound I-90 bridge, flyover bridge over Highway 52 and portion of new ramps and loop
• 2026: Constructed new westbound I-90 bridge and remaining portion of new ramps and loops

Improvements

A new feature, a flyover ramp, for southbound Highway 52 to eastbound I-90, will solve several problems:

• Remove 92% of left-hand turns, reducing the risk for t-bone crashes
• The dedicated ramp will get rid of the line of vehicles that wait to turn

New ramps will reduce the run-off-the-road crashes:

• Changing the angles will allow for better, more controlled entrance/exit
• Lengthened accelerations lanes will also improve conditions

The bridge replacements will allow for:

• Relocation of the bridge piers that block the view of on-coming traffic
• Improved bridges that will last another 60 years or more
