A man driving a car with Columbiana County plates was flown to Mercy Medical Center in Canton Wednesday night after his 2000 Chrysler 300 collided head-on with a tractor-trailer rig on U.S. Route 30 just west of state Route 9 in Kensington. Patrol Sgt. Troy Homrighansen, who is investigating the crash, believes the car went left of center. The trucker was not hurt although his rig suffered extensive damage. No further details were available.
