A 20-vehicle pileup closed northbound Interstate 35 near Owatonna, Minn., late Thursday morning for about three hours.
Icy roads along with blowing and drifting snow made travel hazardous Thursday, causing 20 passenger cars to slip, slide and crash and six semitrailer trucks to jackknife.
Some involved in the crash received minor injuries, said State Patrol Sgt. Troy Christianson. With part of the highway closed, northbound traffic was detoured about one mile north of Hwy. 14.
By noon, the damaged vehicles had been cleared.
