100 Cars Crash in Huge Pennsylvania Pileup Chain Traffic backed up for miles By Kevin Spak, Newser Staff Posted Feb 14, 2014 9:58 AM CST 22 comments Comments An overturned car is seen in this screenshot from NBC 10's live feed. (NBC 10 Philadelphia) (Newser) – More than 100 cars and dozens of tractor trailers have been caught up in a chain of accidents stretching over several miles of the Pennsylvania Turnpike in Bensalem this morning, backing up traffic for several more miles behind that. The first accident came at about 7:45am on the westbound side, causing a rubbernecking delay on the eastbound side—where the subsequent crashes occurred beginning at 8am, Fox 29 Philadelphia reports. Icy conditions are believed to be responsible—though residents say that stretch of road is so notoriously treacherous that accidents sometimes occur there in good weather. One crash site involves roughly 75 cars and several tractor trailers, CBS 3 Philadelphia reports. Another 30 cars were involved in another big wreck, in which a tractor trailer jackknifed, reportedly landing on top of at least four cars. Emergency crews are now using the westbound side to transport out the wounded. At least five people have been hospitalized so far. This is "the worst accident I have seen in the 20 years I have been doing this," CBS' traffic reporter said.
