COLUMBIA COUNTY -- 20 people were hurt when a semi truck hit a school bus carrying students from a Milwaukee-area private school Wednesday morning, according to the Wisconsin Department of Transportation.
Four of the injuries are serious, the DOT says. The severity of the other injuries is not yet known.
The crash happened just after 10:00 a.m. on I-39 northbound, near DeForest. The DOT says the semi crashed into the school bus, which was parked on the shoulder of the interstate after pulling over due to a mechanical issue.
Students who were not injured are being transported to the State Patrol Post in DeForest for reunification with family members.
