Traffic impacts
Both I-90 bridges are open, as are the ramps. Crews continue to be on site doing work that may require periodic lane closures, so please continue to stay attentive in this work zone through October.
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: Construct 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
