The detour will run from 11 p.m., June 17 to 1:30 a.m., June 18, weather permitting. Vehicles on westbound I-90 will be detoured north on Highway 61 to Highway 43 in Winona, which will then connect them back to I-90.
- I-90 lane closures lane closures will continue for the resurfacing work and will remain in place through late fall.
- I-90 eastbound on-ramp at Nodine from Winona County Road 12 will be detoured beginning May 11.
