PIERRE — Both eastbound and westbound lanes of Interstate 90 remain closed from Rapid City (exit 67) to Sioux Falls (exit 395) due to sustained high winds causing blizzard-like conditions. As high winds move east, low visibility and drifting snow are worsening.

The current closure on I-90 has been extended from Sioux Falls (exit 402) to the Minnesota state line at 7 p.m. on Thursday, Dec. 22, 2022.

The National Weather Service (NWS) has issued a blizzard warning in effect through Friday, Dec. 23, 2022. In addition to blizzard-like conditions, many stuck and stranded vehicles are blocking lanes of traffic.

Due to continued high winds causing near zero visibility and drifting snow, along with ongoing issues with stranded motorists, SDDOT anticipates the I-90 closure to remain in place through Thursday and into Friday, Dec. 23, 2022.

Officials will continually assess conditions to determine when I-90 can be reopened safely.


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.

Our newsroom occasionally reports stories under a byline of "Mitchell Republic." Often, the "Mitchell Republic" byline is used when rewriting basic news briefs that originate from official sources, such as a city press release about a road closure, and which require little or no reporting. At times, this byline is used when a news story includes numerous authors or when the story is formed by aggregating previously reported news from various sources. If outside sources are used, it is noted within the story.
