I-90 To Remain Closed Travel Caution

For Immediate Release: Saturday, November 30, 2019

Contact: Kristi Sandal, Public Information Officer, Kristi.sandal@state.sd.us


PIERRE, S.D. – The South Dakota Departments of Transportation and Public Safety are advising motorists that Interstate 90 will remain closed from Chamberlain to the Wyoming border at least overnight and crews will reassess conditions Sunday morning.


Officials with the South Dakota Highway Patrol are advising motorists and truck drivers that accommodations are very limited in Chamberlain and to remain where you are until an announcement is made for the reopening of I-90.


A blizzard warning and winter storm warning continue to be in effect throughout most of the state until sometime Sunday morning. Many roads are ice covered, snow-packed and slippery, and have heavy drifting. Motorists are asked to postpone any travel until weather and road conditions improve and heed the many posted No Travel Advisories.


Drivers trying to avoid the closures are reminded that other state highways and county roads will likely not be any better and may be worse.


Be sure to visit www.safetravelusa.com/sd or call 511 to check the latest road conditions and travel advisories before heading out. There is also an app (SDDOT 511) available for Android and iOS devices. Sign up for ClearPath511 for closure notifications by text message or email.


Travelers are reminded that SDDOT crews will plow until early evening hours as conditions allow. After that, winter maintenance will be suspended and will resume about 5 a.m. the next morning, weather permitting.


If you must travel, the departments of Transportation and Public Safety recommend travelers also take the following steps.

  • Wear your seatbelt
  • Travel during the day
  • Drive with your headlights on (not daytime running lights) so you can be seen by other motorists from the front and rear
  • Don’t use cruise control on icy or snow-covered roads
  • Use highly traveled roads and highways
  • Keep family and friends informed of your travel schedule and route
  • Call 511 or visit safetravelusa.com for road conditions
  • Keep a winter weather survival kit in your car.  The kit should include blankets, warm clothing, water, energy bars, a flashlight, a distress flag, a shovel and matches
  • Travel with a charged cell phone, but don’t rely on it to get you out of a bad situation

§    Change travel plans as weather conditions warrant


If you do get stranded:

§    Stay in your vehicle

  • Run the engine and heater about 10 minutes an hour to stay warm
  • When the engine is running, open a window slightly to prevent carbon monoxide poisoning.  Periodically clearing snow from the exhaust pipe will also help prevent carbon monoxide buildup
  • When it’s dark outside, turn on the interior light so rescuers can see you
  • Put up a distress flag, or spread a large colored cloth on the ground to attract attention from rescuers
