UPDATE, 12:30 p.m.: Authorities are reopening South Dakota interstates as plow crews continue to make progress removing snow.
I-90 from Mitchell to Vivian was reopened late Thursday morning, as was I-29 from Sioux Falls to Brookings.
The South Dakota Department of Transportation said they expect the remaining portions of interstates still closed to be reopened sometime Thursday afternoon.

Snowfall accumulation from a massive winter storm is ending Thursday, but forecasters say dangerous conditions persist across South Dakota as bitterly cold temperatures settle in.
Strong winds continue to blow recently fallen snow, resulting in hazardous driving conditions across the region.
Interstate 29 remains closed from the North Dakota border to Sioux Falls, while Interstate 90 is closed from Sioux Falls to the Vivian exit. No travel is advised on virtually every state highway east of the Missouri River.
Icy roads left some motorists stranded in sub-zero temperatures. The Highway Patrol said five people needed to be rescued from a car stuck near Webster.
Thanks to the help of a DOT plow truck and Webster Police Department, 5 people were rescued from a vehicle stuck on US 12 near MM 339 (just west of Webster). US 12 westbound is drifted over and impassible. Even highly traveled roadways are impassible. #keepSDsafe pic.twitter.com/rTUN7QidTs
