Seven people were hurt in a 10-vehicle crash Thursday that closed the part of Interstate 83 for hours and tied up traffic throughout much of southern York County.

A state police spokesman said the crash happened about 1:30 p.m. in the northbound lanes near the Glen Rock exit (Exit 8), when a tractor-trailer rear-ended another vehicle.

Trooper Rob Hicks said a tractor-trailer in the passing lane didn't slow down in time and crashed into the back of a vehicle, setting off a 10-vehicle chain-reaction crash that led to the pileup.

All told, four tractor-trailers, five cars and a flatbed tow truck that was hauling two vehicles were involved in the crash, he said.

"At this point it looks like the seven (people hurt) had non-life-threatening injuries," Hicks said; they were taken to York Hospital for treatment.

Traffic snarled: Emergency crews closed both sides of the highway just after the crash but were able to open one southbound lane a short time later.

That did little to ease congestion in the area.

Susquehanna Trail South in the area of the crash was clogged with traffic as drivers tried to deter around the crash.

At one point, northbound traffic on I-83 was backed up to at least the Maryland line, and southbound traffic was snarled to the Leader Heights exit (Exit 14).

The second southbound lane reopened about 5 p.m. but both northbound lanes remained closed until about 8:15 p.m. as crews cleaned up the mess.

Several of the cars involved ended up on their roofs, and the tow truck tipped on its side. A tractor-trailer ended up on top of the tow truck, with its front tires about 6 feet off the ground.

There was a diesel fuel and hydraulic fluid leak, but it was contained by a hazardous-materials crew, Hicks said.
