A disabled truck blocking one lane of I-95 South had traffic backed up for at least a couple of miles this morning in Bensalem.
One eyewitness described narrowly escaping as the accident developed around him - a car losing control in front of him, a truck behind him.
Mike Elek, an executive producer for Philly.com, was commuting from Ewing, N.J., about 9 a.m. when a car passed him, began to swerve, and tried to pull off the road.
"I heard the screech of tires, and looked in my rearview mirror," he said. He saw a large truck in the middle lane lose control, strike the leftside concrete barrier, "and then careen across all three lanes before coming to a stop."
