20-Car Pileup On Icy Philadelphia Interstate

"Flash-freezing" led to a pileup involving more than 20 cars on a major interstate outside Philadelphia on Sunday, a transportation department spokesman said. All lanes of Interstate 76 were closed west of Philadelphia after a series of cars slammed into one another amid freezing rain around 6:30 a.m., PennDOT spokesman Eugene Blaum said. The extent of any injuries was not immediately clear.Slick roads caused a number of crashes, including collisions that also closed parts of Interstates 95 and 476 in and around Philadelphia.
