Traffic impacts

Highway 52 detour Sept. 28-30

Highway 52 is scheduled to be closed 1 a.m., Monday, Sept. 28 to 9 p.m., Wednesday, Sept. 30, including access to the flyover bridge for southbound Highway 52 to eastbound I-90. Westbound I-90 to northbound Highway 52 will be open.

Detours:

• Northbound Highway 52 motorists should go north at Olmsted County Road 7 north of Chatfield to I-90 and merge onto westbound I-90. Use Exit 217 to go northbound on Highway 52 to Rochester.
• Southbound Highway 52 motorists should exit onto Highway 63 southbound in Rochester, travel south to I-90 at Stewartville. Merge onto eastbound I-90 and exit at Exit 224 at Eyota. Travel south on Olmsted County Road 7 to Highway 52 north of Chatfield.
• Eastbound I-90 motorists who want to travel south on Highway 52 will exit at Exit 224 at Eyota. Travel south on Olmsted County Road 7 to Highway 52 north of Chatfield.
• Westbound I-90 motorists exit at Exit 224 at Eyota to travel south on Highway 52. Travel south on Olmsted County Road 7 to Highway 52 north of Chatfield. To travel north on Highway 52, use Exit 217 onto northbound Highway 52.

I-90 lane closures at Highway 52

• Single-lane traffic for both directions of I-90 in the eastbound lanes.

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
