Traffic Impacts

Road closures

  • Begins March 27, 2017 - Ends October 2017 for the winter.
  • 2017 Detour will be necessary for southern segment to replace bridges, culverts and where pavement is reconstructed. The detour includes Highway 30, Highway 83 and Blue Earth County Road 90.
  • MnDOT encourages people to use the official detour for the following reasons:
    • The pavement on the detour routes is designed for heavy trucks and large traffic volumes.
    • The detour route has better safety features including wider shoulders, gentler curves, and clear signing.
    • Using other routes may result in more maintenance and dust problems for local road authorities.
  • However, Highway 22 north of County Road 16 is a public road that is open to traffic so it is not illegal to drive on it.
  • Please use the official detour to reduce the negative impacts of using local roads.

  • 2018 Detour will be necessary for northern segment and construction of roundabout at Hwy 22 and CR 90
