The 18-year-old woman driving the first car lost control and rolled over into the median strip. She was seriously injured and transported to Anna Jaques Hospital in Newburyport for treatment.

Her passenger, a 37-year-old woman, was ejected from the car and pronounced dead at Anna Jaques Hospital a short time later. Her name has not yet been released.

The driver of the second car was not injured.

State Police say the crash remains under investigation.
