Original story

Interstate 90 is closed from Wall to Chamberlain, both east and westbound lanes.

The closure is due to the blizzard which has started to make its way through South Dakota. The storm includes heavy snow, high winds, rain and freezing rain. Those factors will make travel difficult in many parts of the state.

Flooding over roads is also being reported in southeast and south central South Dakota as well. Flooding conditions can change quickly and travelers are encouraged to call 511 or visit for the most current conditions.

Travel will become more difficult as the day goes on throughout South Dakota. State officials recommend that motorists not try to travel Thursday.

Department of Transportation maintenance crews have been out since 4 a.m. and those that have not already been pulled off highways will be brought in off highways at nightfall.

More interstate closures and No Travel Advisories on other highways are likely today and Thursday.

Motorists should visit or call 511 to check the latest road conditions and travel advisories before attempting to travel. Conditions will be updated around 7 or 8 p.m. Wednesday and then again Thursday between 4 and 5 a.m.
