Mass Pike Interchange

The Mass Pike Interchange is a location in the Commonwealth in 2287.

Background
Part of the Massachusetts Turnpike before the Great War, the interchange between two elevated freeways served travelers heading north-south and east-west. The intersection is situated near Lake Cochituate, west of Boston. By 2287, Mass Pike Interchange has become inhabited by the Gunners, who have established an outpost on the freeway's ruins.

Layout
Sitting atop the western freeway, it consists of two roads: the freeway and the old highway. The old highway connects Mass Pike Tunnel west to the interchange and leads to the Nuka-World transit center at the west end of the highway. At the bottom and top of the freeway, the Sole Survivor will come across several Gunners. There are two elevators that can be used to reach the upper and lower sections of the freeway. The elevator to the lower freeway is located north of the interchange, while the second is located in the middle of the interchange, guarded by several Gunners. The uppermost section contains very few Gunners, while the lower section has several and an Assaultron, as well as a Gunner commander with power armor (T-45/T-51 and very rarely T-60). It also consists of numerous shacks containing loot. Near the power armor station, there is a shack that contains several items and a crate containing rare loot.

Notable loot

 * Grognak the Barbarian issue #7 - In the commander's shack sitting on top of the toilet.
 * Leveled power armor pieces - On the power armor station next to the Gunner commander's shack. Nearby Gunners will enter the power armor if alerted to the Sole Survivor's presence.
 * A standing power armor - On the road northwest of the Mass Pike Interchange at a military checkpoint. Going west to Poseidon reservoir, one will see a couple of burned cars and a truck full of cigarette machines. Right beside the door.
 * Two bottlecap mines - In the shed behind the weapons workbench.
