Beginning April 4: Eastbound I-90 traffic is reduced to one lane west of Mower Co. Rd. 15 to east of Olmsted Co. Rd. 6. This will last through the end of the project in late August.
Beginning April 4: Eastbound entrance ramp to I-90 at Co. Rd. 6 is closed and detoured.
Go east on Co. Rd. 6 into Stewartville then north on Hwy 63 to the I-90 interchange.
Beginning April 25: Westbound I-90 motorists west of Stewartville will have single-lane traffic through the work zone near Olmsted Co. Rd. 6. This will last for approximately three weeks.
Beginning May 9: High Forest Rest Area will be closed. It is scheduled to re-open Thursday, June 30 and all construction work is expected to be complete in August.
May 25 and 26: Motorists on eastbound I-90 will encounter brief off-ramp closures at High Forest (Olmsted Co. Rd. 6) and Stewartville (Hwy 63).
People can use the Hwy 63 ramp while Co. Rd. 6 is closed and use the Co. Rd. 6 off-ramp when the Hwy 63 ramp is closed.
The ramps will be closed just during the work to remove the pavement and again to pave the ramps but will be open each day by evening.
Timeframe TBD: Detour will be required for the ramp work on Hwy 63 interchanges.
