Pennsylvania State Police (PSP) have released more information about Wednesday’s deadly pileup crash that involved dozens of semi trucks.

The crash occurred at 3 p.m. on December 16 in the westbound lanes of I-80 in Greene and Lamar Townships.

A winter storm was moving through the state at the time that the crash occurred and travel restrictions were in place on many roadways in the state.

PSP says that a total of 66 vehicles were involved in the pileup along a one mile stretch of interstate. Troopers say that 11 of the vehicles were cars and the other 55 were commercial vehicles.

Police also clarified that one person traveling in a passenger vehicle died as a result of the crash. A second person who was caught up in the traffic backup caused by the pileup suffered a medical emergency and also passed away.

According to a statement released by PSP around 1 p.m. on Thursday, I-80 westbound remains shut down as crews work to remove wrecked vehicles. I-80 eastbound is also restricted in the area to allow for vehicle removal.
