South Dakota DOT

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.

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.
