Officials with the state Departments of Transportation and Public Safety say white-out conditions with zero to near zero visibility, icy roads, drifting snow, as well as multiple accidents and stopped vehicles are making safe travel almost impossible in some areas.
That segment of Interstate will remain closed until conditions improve and crews are able to clear the roadway.
Department of Transportation officials have also suspended winter maintenance in some areas around Mobridge and Pierre due to zero visibility and safety concerns. As conditions continue to deteriorate, maintenance activities may be suspended in other areas of the state as well. Crews will resume winter maintenance activities when it is safe to do so.
Travelers are urged to visit safetravelusa.com/SD or call 511 to check road conditions across all of South Dakota as this storm moves from west to east during the day today (Monday) and into Tuesday morning. Officials caution travelers to watch the weather and be prepared to change travel plans if necessary.
Motorists are reminded that state law includes both criminal penalties and a civil fine of up to $1,000 for being on a closed highway. Motorists found traveling on any closed portion of Interstate will be in violation of state law. A stranded traveler could also be charged for the cost of a rescue effort, up to $10,000.
