Interstate 90 Closing


Motorists in eastern, South Dakota are seeing their first signs of the winter storm this evening.  Across western, South Dakota law enforcement and emergency crews have been busy responding to a large number of collisions throughout the day caused by slippery highways.

The state of South Dakota is planning on closing Interstate 90 in western, South Dakota at midnight CST tonight.  From Wyoming / South Dakota state line to Chamberlain, motorists will not be able to travel that section of the highway.

The South Dakota Department of Transportation has already issued no travel advisories for US Highway 85, US Highway 212 in western, South Dakota, US Highway 14 from near the Pierre area west towards Philip, US Highway 83 from Interstate 90 to Gettysburg and US Highway 18 in southwest, South Dakota.  The department has reported that winter maintenance will be suspended for tonight and will resume about 5 a.m. the next morning, weather permitting.  For the latest road conditions in South Dakota, please visit or call 511.
