• I-29 (northbound and southbound) from Sioux Falls to Brookings reopened at 11 a.m. Central.
• The remaining sections of I-29 closed between Brookings and the North Dakota state line had significant drifting and cleanup is still being done. Progress will be monitored.

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 is asking for extra caution and reduced travel speed.

No-travel advisories continue to impact state highways across the eastern half of the state of South Dakota, with many highways physically impassable from blockages of large snow drifts, stranded vehicles, and completely plugged bridges.
