Travel Conditions

Due to the extremely cold temperatures and windy conditions, applying chemical and salt are not effective treatment options. The SDDOT advises:

  • 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.
  • Please use extra caution and reduce travel speed.

No Travel Advisories continue to impact state highways across South Dakota, with many highways physically impassable from blockages of large snow drifts, stranded vehicles, and completely plugged bridges.

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.
