  • I-90 (eastbound and westbound) from Mitchell to Chamberlain has been reopened.
  • The remaining section of I-90, Chamberlain to Kadoka, will be reopened by mid-day.

Due to the cold temperatures and windy conditions, applying chemical and salt are not effective treatment options.

  • Travelers should expect to encounter ice-covered, slippery roads, and snow covered shoulders. 
  • Snow removal equipment will be working to remove ice in the driving lanes and snow remaining on shoulders.
