Extreme Weather: Blizzard Conditions Shut Dozens Of Roads And Highways In Dakotas, Wyoming
KEY POINTS
- U.S. 12 is 'solid ice,' South Dakota highway patrol said
- 85 miles of I-29 is also closed to traffic, transportation officials said
- I-25 between Douglas and Glenrock in Wyoming is also closed
More than a hundred miles of Interstate 90 have been shut down indefinitely due to blizzard conditions in South Dakota and some of its neighboring states in the Northern Plains. Transport officials have warned that closure may last for days.
"I-90 from Rapid City to Murdo and I-29 from Watertown to the North Dakota border are closed," the South Dakota Department of Transportation (SDDOT) said in an alert on its website late Tuesday. "No vacancies in Murdo. Adjust travel plans and seek shelter elsewhere. Expect multiple day closures," the SDDOT said.
The closures cover more than 140 miles of I-90 and about 85 miles of I-29, as per CNN. The highway patrol also warned that U.S. 12 near Summit, South Dakota was "solid ice and hard to even walk on," making the route "impassable."
The Pennington County Sheriff's Office said Sage Creek Road "is totally blocked." The office also posted a photo of a truck that tried to get around the I-90 closure but got stuck instead. "Even if roads and weather look improved, they are not," the office reiterated.

The North Dakota Department of Transportation (NDDOT) shut down multiple roads due to extreme weather. U.S. 2 from Devils Lake to Grand Forks was closed "due to blowing snow causing very icy roads and areas of zero visibility," the office said. U.S. 52 from Jamestown to Fessenden was also shut down for the same reasons.
Other roads that are currently closed in North Dakota are I-94 between Fargo and Bismarck, I-29 between Fargo and the South Dakota border, Highway 46 between I-29 and Streeter, Highway 13 between Wahpeton and Linton, Highway 11 between I-29 and Highway 83, and Highway 281 between Jamestown and the South Dakota border, local radio station KFGO reported.
Officials at the NWS in Bismarck said heavier snow is expected in parts of the state through Wednesday. The highest snow totals are expected in Lisbon, Carrington and Langdon (up to 9 inches), Fargo (up to 10 inches), and Grand Forks (up to 12 inches).
