State troopers said one person was killed in a crash involving a tractor-trailer on Interstate 85 in Salisbury early Thursday morning. Troopers told Channel 9 that the crash happened just after 5 a.m. in the northbound lanes of I-85 near mile marker 74. Troopers said a woman was driving in the northbound lanes when her car stalled on the interstate. When she got out of the car, a tractor-trailer collided with her vehicle, and struck the woman. She was pronounced dead at the scene. Her name has not been released. Officials said the collision ignited a fire but that the driver of the tractor-trailer will be OK. All northbound lanes of I-85 were blocked while crews investigated the crash, and officials don't expect the highway to reopen until 3 p.m.
