COLUMBIA COUNTY, Wis. (WBAY) - Twenty people were hurt when a semi truck rear-ended a school bus in south central Wisconsin on Wednesday morning, according to the Wisconsin State Patrol.
The crash happened on I-39/90/94 at mile marker 122.4 in Columbia County, according to our partner station WMTV. This is near Lodi.
The school bus was carrying students from a private Milwaukee area school to Wisconsin Dells when the driver pulled on to the shoulder of I-39 due to a mechanical issue.
A semi truck hit the bus from behind. At the time, officers were trying to locate the semi because of 911 calls that it was driving erratically.
Thirty-three people were on the school bus at the time of the crash.
Four suffered serious injuries, including two people who were airlifted to area hospitals. A state patrol sergeant says these don't appear to be life-threatening.
UW Health has received nine patients from the crash. SSM Health said 11 people were being treated at St. Mary's Hospital in Madison.
The northbound lanes of the highway were closed for about two hours.
