Traffic impacts
Highway 52 detour on Aug. 17, 5 a.m. to 10 p.m.
Crews will be pouring the entire I-90 westbound bridge deck, which spans over both north and south Highway 52. It will close Highway 52 north and south of the bridge, including the southbound Highway 52 to eastbound I-90 flyover bridge. All Highway 52 traffic must use the detour routes. (Detour was orginally scheduled for Aug. 14 but it was postponed due to rain forecast.)
Southbound Highway 52 detour:
- In Rochester, motorists should travel south on Highway 63 to Stewartville and then east on I-90 to Exit 224 (Eyota) and travel south on Olmsted County Road 7 to connect with Highway 52 north of Chatfield.
Northbound Highway 52 detour:
- Motorists should take Olmsted County Road 7 north to the westbound I-90 entrance ramp at Eyota, travel west to Exit 209B at Stewartville to travel north on Highway 63 into Rochester to connect with Highway 52.
New flyover ramp open from southbound Highway 52 to eastbound I-90
Instead of making a left turn at grade in front of northbound Highway 52 traffic, motorists travel on the ramp that carries traffic over northbound Highway 52 to eastbound I-90.
Southbound Highway 52 traffic:
- Going to eastbound I-90, take the right lane to go onto the ramp that curves over northbound Highway 52 and onto the eastbound I-90 on-ramp toward Eyota, St. Charles, Winona and La Crosse.
- Continuing south on Highway 52, take the left lane, which will carry traffic under I-90 and continue south toward Marion, Chatfield and Preston.
Northbound Highway 52 traffic:
- Going to eastbound I-90, take the right lane to the eastbound I-90 on-ramp. Watch as southbound Highway 52 traffic traveling to eastbound I-90 merges past the bridge.
- Continuing north on Highway 52, take the left lane, which will be adjacent to the oncoming southbound traffic.
I-90 westbound to northbound Highway 52 exit detour 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 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.
