Motorists traveling on Interstate 90 will encounter off-ramp closures to Highway 52 southbound through November southeast of Rochester, according to the Minnesota Department of Transportation.

I-90 eastbound and westbound motorists wanting to go south on Highway 52 should use Exit 218 , travel north on Highway 52 and exit at 50th Avenue, turn left and exit to southbound Highway 52. I-90 motorists can also take Exit 224 near Eyota and go south on Olmsted County Road 7 to access Highway 52 north of Chatfield.

I-90 eastbound and westbound motorists exiting to Highway 52 will be able to go north on Highway 52.

It is anticipated the ramps will reopen to traffic in November. People can view www.511mn.org or the free mobile app to see traffic impacts and updates on schedules.

Additional traffic impacts are scheduled for this summer. A culvert will be installed under Highway 52 at the I-90 interchange and that area will be closed and detoured. Work is tentatively scheduled in August and will last a few days. The schedule will be communicated once it is determined. The following is the detour for the culvert work:

Motorists going north on Highway 52 should go north on County Road 7, exit to westbound I-90 and take the Highway 52 exit to access northbound Highway 52.

Motorists going south on Highway 52 should go south on Highway 63, exit to eastbound I-90 and take the Highway 52 exit to access southbound Highway 52.

This work is part of a three-year project that started July 15. During the project, crews will be replacing the I-90 bridges over Highway 52, constructing a new ramp for southbound Highway 52 to eastbound I-90, reconstructing all ramps and loops and replacing large culverts under interchange ramps.

The project is expected to improve safety on the interchange ramps and intersections, increase clearance under the I-90 bridges over Highway 52 and improve traffic flow and reduce traffic delays through the interchange, which is a busy commuter and freight route.
