A 29-year-old woman from Mattapan was struck by a vehicle inside the O'Neill tunnel after she reportedly exited from a moving Uber vehicle during the Monday morning rush-hour. The victim— who is in critical condition at Tufts Medical Center this afternoon— was coming from Logan Airport, according to an update from State Police.

"The driver made an agreement to drive her fare to her residence in Boston for an agreed upon price," a State Police account read. "While driving on Route 93 southbound inside the tunnel, just prior to Exit 23, the victim exited the moving vehicle from the rear passenger side door. The victim was then struck by a 2015 Jeep Cherokee being operated by a 31-year-old Charlestown man."

The incident happened around 7:30 a.m. It remains under investigation.
