UPDATE, 9:30 a.m.

State officials have reopened Interstate 29 after temporarily closing it due to poor driving conditions.

The South Dakota Department of Transportation announced I-29 was opening around 9:30 a.m. Tuesday. I-90 between Sioux Falls and Murdo remained closed, however.

Both Interstates were closed Monday due to a blizzard that pummeled most of eastern South Dakota.

Department of Public Safety spokesperson Kristi Sandal said Officials want to strongly caution motorists that even though I-29 is open and passable, the highway is extremely icy and speeds will be greatly reduced. Drivers are encouraged to only travel if absolutely necessary.

Officials are seeing crashes this morning where drivers are underestimating and overdriving road conditions.

Snow is beginning to taper off, but winds will remain strong throughout the afternoon making safe travel challenging throughout the day and into the evening.

The South Dakota Department of Transportation has expanded it's closure of Interstate 90 to Sioux Falls.

The interstate is now closed from Murdo to Sioux Falls in both directions.

In addition, the SD DOT closed I-29 from the North Dakota border to Sioux City, IA.

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.

Earlier story:

Authorities have closed down a portion of Interstate 90 in central South Dakota due to a blizzard causing poor driving conditions in the area.

I-90 between exit 192 at Murdo and exit 332 at Mitchell is closed, according to the South Dakota Department of Transportation. This includes traffic in both east and westbound lanes.

Officials say strong winds with 50 mph gusts are causing white-out conditions with zero to near zero visibility, icy roads and drifting snow making safe travel almost impossible along this stretch of I-90 and on many other highways in the state.

That segment of Interstate will remain closed until conditions improve and crews are able to clear the roadway.

Officials are also cautioning drivers that strong winds of 30-40 mph and gusts up to 50 mph are making travel extremely difficult, especially for semi-trucks and other high-profile vehicles and asking motorists and semi-truck drivers to change travel plans until conditions improve.

Winter maintenance has been suspended in some areas where it is too dangerous for the plows to be on the roadway. Operations will resume once it is safe to do so.

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.
