PIERRE, S.D. – Officials with the South Dakota Department of Transportation and the Department of Public Safety are closing Interstate 90 from Mitchell to Sioux Falls (east and westbound) effective immediately – Monday, March 5, 5:27 p.m.


I-90 is now closed from Murdo to Sioux Falls.


Interstate 29 will close from the North Dakota border to the Iowa border (north and southbound) at 6:30 p.m. CST tonight.


No Travel Advisories are posted on many highways as roadways are snow-packed and icy. Heavy snow and strong winds gusting upwards of 50 mph, are making safe travel nearly impossible on the Interstate and most highways in eastern South Dakota.


Winter maintenance will be suspended in the early evening hours and travel will not be advised during the overnight hours.


The National Weather Service has issued a blizzard warning until 6 p.m. CST, Tuesday, March 6, 2018, for several counties in northwestern, north central and central South Dakota. Winter weather warnings and advisories are in place for other areas of the state.
