PIERRE, S.D. – Interstate 29 and Interstate 90 in South Dakota reopened to traffic as of 10 a.m. (CT) on Sunday, March 15, 2026. Motorists are advised that while Interstates and State highways have reopened, extremely difficult driving conditions are expected today due to blowing snow and poor visibility. No Travel Advisories continue to be in place on highways across South Dakota at this time.

Travelers should expect to encounter ice and snow covered roads. With the forecasted sustained high winds, visibility will be reduced due to falling and blowing snow. Please use extra caution and reduce travel speed.
