PIERRE, S.D. – The combination of freezing rain, accumulating snow, and strong winds is causing snow and ice covered roads along with blizzard-like conditions throughout the state. Conditions are forecasted to continually deteriorate throughout the day, with travel becoming extremely difficult to impossible.

The following Interstate closures are planned for Friday, March 31, 2023:

  • Interstate 90 (eastbound) will be closed from Rapid City (exit 67) to Chamberlain (exit 265); and closed from I-90 westbound from Chamberlain to Wall at 12 p.m. (noon) (CT)
  • Interstate 90 (westbound ONLY) from Wall to Rapid City will remain open.
  • Interstate 29 (northbound and southbound) is scheduled to close from Watertown (exit 177) to the North Dakota state line at 2 p.m. (CT)

Secondary Highways:
No Travel Advisories are also expected to be placed on secondary highways throughout South Dakota due to high winds, blowing snow, and low visibilities associated with this winter storm system.

Motorists should not use secondary highways to avoid Interstate closures. Significantly reduced visibilities and blizzard-like conditions,, will make travel very dangerous.
