BISHOPVILLE, S.C. -- An 82-year-old Florence woman is dead after her car crossed the median on Interstate 20 in Lee County and collided with a tractor-trailer.

Coroner Larry Logan says the victim was Johnny L. Rodrigue of Florence. Logan says the force of the impact threw the woman from her vehicle, which was sheared in two in the Monday afternoon crash.

He says she died at the scene.

Logan says the driver of the tractor-trailer was not hurt. Debris from the wreck caused the road to be closed for several hours.

The coroner says she was wearing a seatbelt. An autopsy is scheduled.
