Interstate-29 is currently closed both north and southbound from Sioux Falls to the North Dakota state line. Interstate-90 is closed across the state from the Minnesota state line west to Rapid City. This includes both east and westbound lanes of I-90.
Because of the sustained strong winds causing near zero visibility and drifting snow, the state Department of Transportation anticipates that both interstates will remain closed today.
Along with the interstate closures, the state D-O-T reminds people that no travel is advised on most other state highways and secondary highways.
Road conditions can be found by dialing 511 or visiting sd511.org or using the SDDOT 511 app.
Officials will continually assess conditions to determine when I-90 and I-29 can be reopened safely.
Secondary State Highways:
In addition to the I-90 and I-29 closure, motorists are reminded that many No Travel Advisories and Road Impassable conditions are in place on state highways throughout the state.
Many secondary highways are currently listed as impassable due to high winds, drifting and blowing snow, and low visibility associated with this winter storm system. Motorists should not use secondary roads to avoid Interstate closures.
When listed as Road Impassable, travel on the road segment is physically impossible due to widespread deep snow, drifts, or stranded vehicles. Clearing these secondary roads is expected to be difficult as winds and additional snow are preventing ability to safely and effectively plow or blow the drifted snow, especially with the added issue of stranded vehicles.
Motorists are asked to avoid travel due to the extremely serious weather conditions, and rapidly deteriorating roads. Significantly reduced visibilities and blizzard-like conditions, along with extreme wind chills, make travel very dangerous.
