A tractor-trailer loaded with frozen goods overturned and was dangling precariously on the Interstate 95 overpass near White Marsh last night, forcing state police to close all southbound and northbound traffic on the highway.
Three people were injured, one critically, officials said.
Sgt. Sandra M. Kestner, of the JFK barracks, said the crash occurred at the I-95 overpass at I-695 about 8:50 p.m. Police said the tractor-trailer collided with three passenger cars -- one of which was a disabled vehicle on the shoulder -- and flipped over. A second car went over an embankment. Details were sketchy, but police said the most seriously injured person was flown by state police MedEvac to the Maryland Shock Trauma Center in Baltimore, where a spokeswoman said the victim's condition was critical.
