BRODHEAD - Three were injured, two seriously, in a multi-vehicle crash Monday afternoon on State Highway 11/81, just west of Mt. Hope Road in the Town of Spring Grove.

According to Green County Sheriff's officials, an eastbound car driven by Timothy J. Schwalbach, 52, of Mukwonago crossed the center line at about 3:20 p.m. and struck a semi trailer driven by Ricky L. Westendorf, 43, of Rockford. After the initial impact, Schwalbach's vehicle continued eastbound and struck another vehicle driven by Michael D. Homan, 37, of Brodhead.

Schwalbach and Homan's vehicles suffered severe damage. Homan, who was not wearing a seat belt, was transported from the scene by Janesville EMS.
