Traffic impacts

The new I-90 eastbound bridge and Hwy 52 flyover bridge are completed, and detours are removed. Motorists will travel on the new eastbound I-90 bridge that was built this year. Motorists will also travel under a new Highway 52 flyover bridge, which will begin operation in 2026 closer to the three-year project’s completion. Learn more in the project update email.

About this project

Summary of work

Construction is scheduled 2024-2026 to make changes to the I-90/Hwy 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 Hwy 52 and portion of new ramps and loop
• 2026: Construct new westbound I-90 bridge and remaining portion of new ramps and loops

Improvements

A new feature, a flyover ramp, for southbound Hwy 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
