Northbound traffic on Interstate 95 was delayed for more than an hour last night after a county Fire Department ambulance overturned on the shoulder of the roadway south of Crownsville Road.
The ambulance was on the way to a maintenance shop when it overturned about 7:30 p.m. It was occupied only by its driver, who was not injured, said Division Chief John M. Scholz, a Fire Department spokesman.
State police said motorists were detoured onto other roadways or directed past the damaged ambulance as highway workers removed debris. But traffic backed up for miles.
