BOSTON (AP) – A 23-year-old Arlington resident is dead after his vehicle crashed into an off-ramp barrier in Boston.

State Police say James Lim was driving on Storrow Drive eastbound shortly before 4 a.m. Sunday when the vehicle stuck the protective barrier at the exit ramp, near Copley Square.

Lim was not wearing a seat belt and suffered fatal injuries in the crash. He was pronounced dead at the scene.

State police detectives are investigating the cause of the crash, a standard procedure for fatal collisions on state roadways.
