Leidy Rincon, 29, was one of four women travelling city-bound to work in the Sydney Airport tunnel on General Holmes Drive at Mascot.
She had only been back in Sydney a week after visiting her family in Colombia.
Emergency services were called to the scene after their vehicle was hit by a Ford Falcon that veered into their path at around 5.40am that morning.
“Paramedics did everything they possibly could for her, but unfortunately she died at the scene,” NSW Ambulance Superintendent Katherine Rallings said.
The other three women in the car were taken to hospital for treatment — one in a critical condition.
Christian Lozada, whose mother and girlfriend were in the vehicle, could be seen running through dashcam vision running through the immense traffic, which had backed up around 7km.
“My mother and girlfriend, and two other close friends were in there. I just want to make sure they’re okay,” he told 7 News.
Paramedics treated the other driver, Hashem El-Asmar, 34, who suffered a punctured lung and bone fractures.
He was taken to St George Hospital for mandatory testing, after which he will be interviewed. Police are also testing substances allegedly found in his car.
It’s likely the three other women will remain in hospital until next week.
