A Shobonier woman was injured in a car-semi accident on Interstate 70, west of Montrose, on Saturday afternoon. Illinois State Police reports indicate that a vehicle driven by 87 year old Mamie Whipple of Shobonier was eastbound in the right lane and the semi operated by 55 year old Gerald J. Berwer of Perryville, Missouri was east bound in the left lane. State Police reports say that Whipple attempted to use the authorized vehicles only turnaround in the center median and that Whipple’s vehicle turned in front of Berwer’s semi. Berwer’s semi struck Whipple’s vehicle in the back driver’s side pushing the Whipple vehicle into the ditch on the right side. Whipple’s vehicle then ran off the roadway into the media and came back on to the roadway, sliding sideways causing Berwer’s semi to overturn into the ditch on the right side. Whipple was taken by Air Evac to Carle Hospital in Champaign.
