SISSETON, S.D. (AP) -- Authorities have launched a rescue operation after a ground blizzard stranded dozens of vehicles overnight on Interstate 29 in northeast South Dakota. There are no immediate reports of injuries.
Highway Patrol Lt. Brett Shutt tells KELO-TV that more than 150 vehicles are stuck. A Roberts County dispatcher says "multiple" rescue vehicles have been sent out.
Summit truck stop worker Janet Eastman says the stretch of interstate is roughly 16 miles, between the towns of Peever and Summit. She says it's a valley where snow gets blown in and packs on the interstate. One trucker told KFGO radio that drifts are as deep as four feet.
The interstate is closed between Watertown and the North Dakota border.
