Four-year-old child suffers life-threatening injuries after car flips over in Big Dig Tunnel

A two-car crash inside the Tip O’Neill tunnel early Sunday morning sent several people to the hospital, including a 4-year-old girl who was partially ejected from one of the vehicles.

According to Massachusetts State Police reports, officers responded to a rollover on the northbound side of Interstate 93 around 12:24 a.m. after receiving calls from other motorists about an accident inside the tunnel.

A preliminary investigation of the accident indicates that a Toyota 4-Runner, driven by a 26-year-old Malden man, traveling in the middle-left lane, swerved to avoid colliding with a car that allegedly tried to switch into the 4-runner’s lane.

That car, a Malibu, was driven by a 29-year-old East Boston woman, police said.

To avoid the cars crashing into one another, police said the Malden man swerved to his left, and then swerved right again to avoid smashing into the highway barriers.

“The sudden maneuvers caused the driver to lose control of the 4-Runner, which rolled over and slid to a final resting position on its driver’s side across the middle left travel lane,” according to a police report.

There were several other occupants in the 4-Runner, including a 4-year-old girl who was “partially ejected” from the car.

The child, as well as a 24-year-old Malden woman, a 24-year-old Dorchester man, a 21-year-old Dorchester woman, and a 5-year-old boy, were sent to various Boston-area hospitals following the rollover.

One of the adult women was also ejected from the car, police said.

No charges have been filed at this time, according to police, however, if the investigation confirms that the child was not in a car seat as required by law, the driver of the 4-Runner will be charged accordingly, they said.

The crash is still under investigation.
