UPDATE: SDDOT not reopening anymore interstate sections Saturday

Snow road closed by MGN.


Officials with the South Dakota Departments of Transportation and Public Safety say Interstate 90 will remain closed from Chamberlain to the Minnesota border and I-29 will remain closed from Watertown to Sioux Falls until Sunday.

An opening time has not been determined yet.

SDDOT crews have been working in these areas since early this morning and have been unable to keep ahead of the continued snow and strong winds.


Officials have opened Interstate 90 from Vivian to Chamberlain and say Interstate 29 from Summit to Watertown will open at 3 p.m.

I-90 is closed from Chamberlain to the Minnesota border. I-29 remains closed from Summit Watertown to Sioux Falls.

Officials do not anticipate opening the full length of I-90 and I-29 on Saturday, and some sections are likely to remain closed until Sunday.

UPDATE 11:15 AM:

State officials have reopened Interstate 90 from Wall to Vivian. The stretch of I-90 between I-29 and I-229 in Sioux Falls is open, along with I-229.

I-29 remains closed from Summit to Sioux Falls.


South Dakota Department of Transportation Officials have opened Interstate 29 from the North Dakota border to Summit.

I-29 remains closed from Summit to Sioux Falls. Interstate 90 remains closed from Wall to Sioux Falls.

Travel south of Summit remains extremely difficult to impossible on both the interstate and other state and local highways. DOT crews and state troopers are reporting heavy drifting, stuck vehicles, snow-packed and icy roads and zero visibility.

DOT maintenance crews are working when it is safe to be out. Near zero visibility, continued snowfall and strong winds are hampering efforts to get roads clear.

Officials strongly encourage anyone who has plans to travel south of Summit or east of Wall to stay where you are and stay safe.

At this time, there are no immediate plans to open Interstate 29 south of Summit or Interstate 90 east of Wall and motorists are asked to not anticipate an opening and park at the gates on the interstate. This can cause more problems and hamper snow removal efforts.

“We understand people want to be on the roads and about their business, but we ask for patience while the storm continues to move through the state and our maintenance crews can get the roads clear and safe for travel,’’ said Greg Fuller, director of Operations.
