PIERRE, South Dakota (KTIV)- The South Dakota Departments of Transportation and Public Safety are advising motorists that Interstate 90 will be closing tonight between the Wyoming border and Chamberlain, both east and westbound, at 12 a.m.
The National Weather Service has issued a blizzard warning for the western portion of the state and winter storm warning for much of the rest of the state.
This system will bring heavy snow, strong winds, freezing rain, and below-freezing temperatures creating difficult driving conditions with significant reductions in visibility.
Many highways are ice-covered, and travel is being discouraged tonight into Sunday morning unless absolutely necessary.
Drivers trying to avoid the closures are reminded that state highways and county roads will not be any better and maybe worse.
Be sure to visit here or call 5-1-1 to check the latest road conditions and travel advisories before heading out.
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.
