Westbound I-90 traffic to detour for 3.5 hours overnight Sept. 2 near Dakota

DAKOTA, Minn. – Westbound Interstate 90 motorists near Dakota in Winona County will be detoured for about 3.5 hours beginning at 11 p.m., Sept. 2 for crews to place bridge beams that cross Winona County Road 101, according to the Minnesota Department of Transportation.

The detour will run from 11 p.m., Sept. 2 to 2:30 a.m., Sept. 3, 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. Eastbound I-90 remains single-lane traffic through the work zone but is not detoured.

During the work, crews will be setting three beams for the bridge over Winona County Road 101. The bridge is being built half at a time.

This work is part of the I-90 project between Nodine and Dakota that began May 4. I-90 resurfacing, I-90 westbound bridge replacement over Winona County Road 101 and other road and safety improvements are part of this project.

Other detours that remain in place:

  • Winona County Road 101 is closed and detoured at the I-90 westbound bridge through mid-October. The detour route (JPG) is Winona County Road 12 west at Dakota to Dakota Valley Drive east.
