Summary of work
MnDOT is planning a resurfacing and bridge replacement project 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.
The following is the planned work on I-90 from Nodine to Dakota in Winona County.
- 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.
