20 cars and six jackknifed semis piled up on I-35 northbound near Owatonna Thursday morning, according to the State Patrol.

Only minor injuries were reported, but the crash closed the northbound lanes of I-35 from just after 9:15 a.m. to noon.

The crash occurred one mile north of Hwy. 14 which is just south of Owatonna.

Photos and video of the scene showed several cars and trucks in the ditches next to the interstate as well as a few semis jackknifed.

Slick roads caused crashes all over the state Thursday morning as the ill-timed snow created slick conditions.

UPDATE: I-35 has been reopened.
