WEST CHESTER, Pennsylvania (CNN) -- One person is dead, another was injured and a third was trapped in a truck cab after an accident involving a tractor-trailer and a passenger van on U.S. Route 202 near Philadelphia, police said.

The crash, which happened shortly after 9 a.m., closed the four-lane highway, located in Chester County, both northbound and southbound, according to Patty Mains, public information officer of the Chester County Department of Emergency Services.

A West Goshen Township police news release said three people were involved in the accident and confirmed the fatality.
