Interstate 90 motorists will be detoured 7 p.m. to 5 a.m., for three successive nights (March 22-24), while construction crews remove the Hwy 63 southbound bridge deck over the highway, according to the Minnesota Department of Transportation.
The nighttime closure and detour of I-90 is being done for safety as crews begin the second year of the project north of Stewartville. In 2020, crews replaced the northbound bridge, improved access for motorists merging onto northbound Hwy 63 from east and westbound I-90. They also closed an at-grade access to Hwy 63 from Hwy 30 west.
During the I-90 detour, westbound motorists will exit I-90 at Hwy 63 northbound (Exit 209), proceed north to the Hwy 30 west exit at the Rochester International Airport, return to Hwy 63 going southbound and follow to I-90 where it rejoins the highway. Eastbound motorists will exit I-90 at High Forest (Exit 205) follow Olmsted County Road 6 east into Stewartville, then north on Hwy 63 to connect again with I-90.
The ramp for eastbound I-90 to southbound Hwy 63 remains open at Exit 209A at Stewartville.
Motorists should also be aware of changes that remain in place for Olmsted County Road 8 and Hwy 30:
Detours for motorists in 2021 include:
During the two-year construction project both Hwy 63 bridges will be replaced, Hwy 30 west rerouted, some I-90 exit ramps will be added or realigned and the access to 90th Street SE will be closed and rerouted.
Motorists can find more information on the plans and sign up for email updates at the MnDOT project website at or join MnDOT’s SE Minnesota Facebook group.
Crews continue to follow the guidance of state and federal health officials to help prevent the spread of COVID-19.
