South Dakota to close I-90 from Wyoming to Chamberlain
PIERRE, S.D. – The South Dakota Departments of Transportation and Public Safety announced early Friday evening that, due to an approaching blizzard, Interstate 90 will be closed in both directions between Wyoming and Chamberlain, S.D. The closure will take effect at 11 p.m. Mountain Time (midnight Central Time) Friday, November 29.
The blizzard warning that prompted the closure currently extends until 6 a.m. Sunday, December 1.
The National Weather Service has issued a blizzard warning for the western portion of the state and winter storm warning for much of the rest of the state. This system will bring heavy snow, strong winds, freezing rain, and below freezing temperatures creating difficult driving conditions with significant reductions in visibility.
Many highways are ice covered, and travel is being discouraged tonight into Sunday morning unless absolutely necessary. Drivers trying to avoid the closures are reminded that state highways and county roads will not be any better and may be worse.
The state Departments of Transportation and Public Safety recommend that if you must travel:
- 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
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
State Department of Transportation crews will plow until early evening hours as conditions allow. After that, winter maintenance will be suspended and will resume about 5 a.m. the next morning, weather permitting.
