About this project
Traffic impacts
- 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.
- With the eastbound entrance ramp closed, the detour to enter eastbound I-90 is to go west on I-90 to Exit 257 (Highway 76, Houston), cross over and return to eastbound I-90. The detour is approximately 16 miles. Traffic will be detoured through June 19. The other three ramps will remain open.
- Winona County Road 101 will be closed and detoured during the bridge replacement, which begins May 18. The county road detour is expected to be several months at a time as crews replace the bridge half at a time, while keeping one I-90 lane open.
- The County Road 101 detour route is: Winona County Road 12 west at Dakota to Dakota Valley Drive east.
Summary of work
A resurfacing and bridge replacement project will occur on I-90 between Nodine and Dakota in Winona County. Construction is scheduled to begin May 4, 2026. Work is expected to be completed in November.

- Repave 5 miles of westbound and 4.7 miles of eastbound I-90.
- Replace the westbound I-90 bridge over Winona Co. Rd. 101.
- Replace approach panels and bridge barrier guardrail connections on the westbound I-90 bridge over southbound Hwy 61.
- Improve safety by providing a slight banking of the right lane of northbound I-90 approaching the bridge over southbound Hwy 61.
- Install new guardrail on the eastbound and westbound lanes and improve drainage.
- Install a reinforcement and a synthetic liner to reduce sinkhole risks associated with Karst geology.
- Clean and reestablish rock catchment areas.
