Route 22 westbound has reopened nine hours after a crash near the Airport Road interchange in Lehigh County.
Three people were involved in the crash around 3:30 a.m. Thursday, with one of them ejected and taken to the hospital. The person is listed in critical condition as of Thursday afternoon.
"Upon arrival, they observed a McLaren 720S that impacted a box truck, and there was a large debris field on Route 22 and major injuries to the passenger in the McLaren," said Trooper Nathan Branosky, Pennsylvania State Police Troop M.
Police say the 2018 McLaren, driven by a 40-year-old man, was heading west on 22 when he rear-ended the box truck. The driver of both the McLaren and box truck weren't hurt.
The 30-year-old passenger of the McLaren was ejected and taken to the hospital with serious injuries.
It's unclear whether she was wearing a seat belt, but police say the box truck was not stopped for traffic at the time of impact.
State police and crash reconstruction units closed Route 22 at Airport Road to investigate, detouring motorists all through the morning commute.
"We're asking people for their patience during this investigation. We know it's an inconvenience for a lot of motorists, especially in the morning rush," Branosky said.
Investigators are looking into whether speed was a factor in the crash.
A McLaren is typically valued at just under $300,000.
Route 22 reopened around 12:30 p.m.
