PIERRE | Eastern South Dakota is starting to emerge from a slow-moving storm that held most of the state in its grip Thursday through Sunday.
Officials announced at 8 a.m. Sunday that they were re-opening Interstate 90 from Mitchell to Sioux Falls, and Interstate 29 from Watertown to Sioux Falls.
According to a news release from the South Dakota Department of Transportation, I-90 from Sioux Falls to the Minnesota border re-opened an hour later.
Parts of I-90 had been closed since Friday, when officials closed the interstate from Rapid City to Murdo. As the storm moved east, road closures soon followed.
State officials said heavy snowfall and high winds on Saturday caused a large amount of blowing and drifting snow on roads. Officials cautioned Sunday morning that roads were still icy, and advised motorists to reduce speed and drive carefully.
