At least three people were killed and another several dozen injured in a huge pileup on Interstate 80 in Pennsylvania on Wednesday.
Snow and icy conditions led to”whiteout conditions,” which contributed to the crash.
Clarion County Emergency Services director Vern Smith said as many as 17 vehicles were involved in the crash, which happened in the westbound lanes of the highway in Clarion Township, one mile east of the New Bethlehem-Clarion exit.
The vehicles included tractor-trailers and cars.
Smith says heavy snow reduced visibility to “virtually zero,” and that the road is expected to be closed for hours. Alternate routs include route 322 east and route 66 south.
Almost immediately after the first collision, 911 received 50 to 60 calls about a multi-vehicle accident, Smith told the Pittsburgh Tribune.
The majority of the victims were transported to Clarion Hospital.

Julie Kunselman, director of marketing and physician recruitment at Clarion Hospital, told the Post Gazette they have treated 18 to 20 people for fractures and head and neck injuries.
Some patients have since been discharged, while others with more serious injuries were transferred to other hospitals, she added.
