UPDATE: I-90 reopened following winter storm

PIERRE, S.D. (KSFY) - UPDATE, 11:15 a.m. Monday

All portions of Interstate 90 have reopened, according to the South Dakota Department of Transportation.
______

The South Dakota Departments of Transportation and Public Safety are advising motorists that Interstate 90 will be remain closed overnight into Monday. The closure area is I-90 westbound from Mitchell to Wall and I-90 eastbound from Rapid City Exit 67 to Mitchell.

Weather and road conditions remain very difficult and will remain that way through the night.

Many highways are ice covered, snow-packed and slippery and have heavy drifting. Travel is being strongly discouraged tonight into Monday unless absolutely necessary. Drivers trying to avoid the closures are reminded that other state highways and county roads will not be any better and may likely be worse.

Officials say plows are out where possible, but in many areas the snow is drifting in behind them. Emergency crews are having a difficult time getting to crashes and stranded motorists.

If you must travel, the departments of Transportation and Public Safety recommend travelers also take the following steps.
 Wear your seatbelt
 Travel during the day
 Drive with your headlights on (not daytime running lights) so you can be seen by other motorists from the front and rear
 Don’t use cruise control on icy or snow-covered roads
 Use highly traveled roads and highways
 Keep family and friends informed of your travel schedule and route
 Call 511 or visit safetravelusa.com for road conditions
 Keep a winter weather survival kit in your car. The kit should include blankets, warm clothing, water, energy bars, a flashlight, a distress flag, a shovel and matches
 Travel with a charged cell phone, but don’t rely on it to get you out of a bad situation
 Change travel plans as weather conditions warrant

If you do get stranded:
 Stay in your vehicle
 Run the engine and heater about 10 minutes an hour to stay warm
 When the engine is running, open a window slightly to prevent carbon monoxide poisoning. Periodically clearing snow from the exhaust pipe will also help prevent carbon monoxide buildup
 When it’s dark outside, turn on the interior light so rescuers can see you
 Put up a distress flag, or spread a large colored cloth on the ground to attract attention from rescuers

The South Dakota Departments of Transportation and Public Safety are advising motorists that eastbound Interstate 90 will be closing from Rapid City to Mitchell and westbound Mitchell to Wall at 7 p.m. CST (6 p.m. MST).

The National Weather Service says heavy snow and extremely high winds will pick up early this evening (Saturday) creating hazardous driving conditions with visibility down to zero. This system is not expected to ease up and leave the state until sometime on Monday.

Many highways are ice-covered, and travel is being discouraged tonight into Monday unless absolutely necessary. Drivers trying to avoid the closures are reminded that state highways and county roads will not be any better and may likely be worse.
