Police said Robert John Killian, 48, of Bear, was pronounced dead on the scene of the crash, which happened in the southbound lanes near exit 85 before 6 a.m. Lanes were blocked for about four hours.
Killian, who was driving a white Chevrolet Cavalier, drove onto the right shoulder and was struck by another car as he attempted to get back into the lane, police said. A chain reaction involving another car and a freightliner ensued and the Cavalier was struck from behind by a Mack tractor-trailer. Another driver, John Riddle, 48, was taken to Johns Hopkins Bayview Medical Center with non-life threatening injuries.
The two commercial vehicle drivers were uninjured, police said.
