I-90/Hwy 52 interchange reconstruction

Traffic impacts

I-90 westbound to northbound Highway 52 exit detour begins July 13 for ramp construction

The detour for Exit 218 westbound I-90 to northbound Highway 52 is to travel 8 miles west to Exit 209A at Stewartville and travel north on Highway 63 into Rochester to connect with Highway 52. The detour is scheduled to be removed in late August.

I-90 lane closures, traffic changes begin April 1 at Highway 52

Westbound I-90 motorists at Highway 52 southeast of Rochester will experience lane closures and traffic changes beginning April 1 as the interchange construction project resumes its third and final year.

Beginning April 1:
• Westbound I-90 bridge closes until fall.
• Single-lane traffic for both directions of I-90 begins in the eastbound lanes.
• Westbound I-90 on-ramp closes.

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
