Crews working to remove truck
A tractor-trailer rollover is snarling the morning commute on Interstate 95.
The tanker crashed near Interstate 495, and a lane of travel on the northbound side of I-95 is blocked.
Traffic is backed up for nine miles, according to Massachusetts State Police.
Motorists are urged to seek alternate routes.
