The right lane in the area of the crash was closed for several hours while crews manually clear the oranges, tangerines and Clementines from the roadway.

The spill has been cleaned up and all lanes are now open.

The driver of the rig complained of back pain and was taken to a Pittsburgh-area hospital. There is no word on his name or condition.

A waitress at a nearby truck stop said she heard about the crash but couldn't believe what she saw when she passed the scene.

"My sister called and told me that they jackknifed," said Laura Terry. "I didn't think I'd see it. I thought it was cleaned up. When we saw it, me and my husband, we were just amazed."

The slick roads led to dozens of other minor accidents, most of them in areas north and east of Pittsburgh. There were a few road closures in low-lying areas in the eastern part of the state, where cold rains caused minor flooding.
