The multi-vehicle wreck happened near mile marker 31 in Hamburg, state police said in a release.
A tractor-trailer was headed west in a work zone when it hit the center concrete barrier, troopers said. The collision knocked part of the barrier into oncoming traffic, where the concrete pieces were struck by another tractor-trailer and a Hyundai Santa Fe, according to crash investigators.
The Hyundai rolled onto its roof and one of the passengers was ejected, sustaining "significant injuries," said state police.
Those involved:
- A 28-year-old man from Herndon, Pennsylvania in a 2000 Peterbilt 379
- A 62-year-old man, a 19-year-old man, and an 18-year-old woman, all from Fleming Island, Florida, in the 2020 Hyundai.
- A 42-year-old man from Hildalgo, Texas in a 2018 Freightliner Cascadia.
PennDOT incident maps showed I-78 was shut down in both directions for several hours between the Route 100 exit just west of Allentown and the Route 61 exit in Hamburg.
Both lanes were back open by 6:30 p.m.
