A man involved in a single-car crash off Soldiers Field Road Saturday night died, according to the Massachusetts State Police Department.

The man, police said, was a 68-year-old Lynn resident operating a Toyota Camry, which was a taxi. A preliminary investigation by state troopers indicated the man was traveling westbound from Logan Airport with a 24-year-old female passenger from Cambridge on the way back to her home.

Police believe the man lost control of the taxi near the Weeks Footbridge, which veered off the road and hit a tree on the shoulder.

Police, Boston Fire and EMS officials responded to the incident around 10:30 p.m. Saturday night. The first responding trooper performed CPR on the man before EMS took over and provided emergency care, officials said. The man was transported to Brigham and Women’s Hospital, where he was pronounced dead.

The woman was transported to St. Elizabeth’s Hospital with non-life-threatening injuries. No immediate update on the passenger’s condition was provided.

An investigation into the incident remains ongoing.
