A Lehigh County man died after a two-vehicle crash late Thursday night on Interstate 78.

The man was driving eastbound near mile marker 54 in Lower Macungie Township when his car and a tractor-trailer collided about 11:30 p.m., according to a state police news release. The 22-year-old driver, from Coopersburg, was pronounced dead at the scene. His passenger, a 21-year-old woman from Massachusetts, was taken to a nearby hospital for treatment of her injuries.

No one else was injured.

That section of I-78 eastbound was closed for several hours while police investigated.

Lehigh County Coroner Daniel A. Buglio said an autopsy will be scheduled. The man has been identified, but Buglio said he is not releasing his name to give his family time to grieve.

The crash remains under investigation. Anyone with information is asked to contact police at 610-395-1438.
