Part of the Massachusetts Turnpike, comprising the section of the highway east of the entrance to the Mass Pike Tunnel near central Boston. The highway descends into a trench, and numerous ruined vehicles dot the road. A cooking station is set up just outside the tunnel entrance.
A group of raiders have built an encampment near the entrance, connecting the upper and lower roadways on both the north and south sides.

Mass Pike Tunnel east appears only in Fallout 4.
