Authorities in Iowa say one person has died and several others were hurt after dozens of vehicles collided along a snow-covered stretch of Interstate 35 near Ames Monday afternoon.
That's near the junction with highway 30.
Up to 70 cars, buses and trucks were involved in the string of crashes, which forced the closure of I-35 in both directions.
Officials say the wrecks were caused, in part, by drivers trying to enter the freeway and crashing into existing accidents.
Authorities didn't release the names of those killed or hurt.
Traffic was backed up as the wrecks were cleared.
The Iowa State Patrol says the freeway reopened about 7 p.m.
