Interstates reopen across South Dakota

By: - February 23, 2023 5:02 pm

All sections of Interstate 90 and Interstate 29 are reopened to traffic throughout the state of South Dakota, according to the Department of Transportation.

Interstate 90 between Mitchell and Sioux Falls was reopened at 4:30 p.m. Significant blowing and drifting occurred through this area, and motorists are advised to be aware of continued drifting in the eastbound lanes, especially near bridge ends.

Travel conditions

Due to the extremely cold temperatures and windy conditions, applying chemical and salt are not effective treatment options. Travelers should expect to encounter ice-covered roads and snow covered shoulders. Snow removal equipment will be working to remove ice in the driving lanes and snow remaining on shoulders. The DOT urges extra caution and reduced travel speeds.

No-travel advisories continue to be in place on some state highways.
