L. SAUCON TWP., Pa. – A stretch of I-78 eastbound is back open after a crash closed the highway for six hours.

The crash involved several tractor-trailers and sent at least one person to the hospital.

It happened just before midnight on I-78 eastbound between the exits for 412 and Route 33.

County communication officials say it was initially reported that a gas leak occurred after the crash, but it was unclear how much had leaked.
