PIERRE, S.D. (Dakota News Now) - According to the South Dakota Department of Transportation, as of 12:00 p.m. on Saturday, I-90 and I-29 are open, but drivers should still proceed with caution while traveling.


As of 12:00 p.m. on Saturday, Interstates 29 and 90 are open, according to SD DOT.

There are still no travel advisories in the northeast corner of the state.


Plows are working to clear the remainder of I-29 after Friday’s Blizzard and are planning to have all interstates open by Saturday afternoon.

As of 7:00 a.m. on Saturday, Interstate 90 has been reopened, but Interstate 29 from Watertown to the North Dakota state line remains closed.

The SD DOT would like to remind drivers that although the interstates are reopening, road conditions are still slick and anyone travelling on the interstate should use extra caution, reduce travel speed and do not use cruise control.

No travel advisories still remain on state highways as of Saturday morning.

An additional interstate closure is planned for Interstate 90, from Chamberlain (exit 265) to Mitchell (exit 332) for 5:30 p.m. Friday.

The following interstate closures are planned for Friday, March 31, 2023:

  • Interstate 90 (eastbound) will be closed from Rapid City (exit 67) to Chamberlain (exit 265) and closed from I-90 westbound from Chamberlain to Wall at 12 p.m. (noon) (CT)
  • Interstate 90 (westbound ONLY) from Wall to Rapid City will remain open.
  • Interstate 29 (northbound and southbound) is scheduled to close from Watertown (exit 177) to the North Dakota state line at 2 p.m. (CT)
Secondary Highways:

No Travel Advisories are also expected to be placed on secondary highways throughout South Dakota due to high winds, blowing snow, and low visibilities associated with this winter storm system.

Motorists should not use secondary highways to avoid interstate closures.

Significantly reduced visibilities and blizzard-like conditions will make travel very dangerous.
