Mass Pike Interchange

The Mass Pike Interchange is a location in the Commonwealth in Fallout 4. It is inhabited by the Gunners, and is guarded by a Gunner Commander and an Assaultron.

Layout
Sitting atop a raised section of highway, this small base has an elevator connecting it to a guard post on the ground below it.

Notable loot

 * Grognak the Barbarian: In the Commander's shack.
 * Leveled power armor pieces: Either on the Commander's body, or on the power armor station next to his shack. During the quest Long Road Ahead it will be on one of the targets. If you manage to sneak kill the defenders without alerting the captain, she will not enter the power armor, and you can collect the frame as well.
 * On the road going west to Poseidon Reservoir you can find a standing power armor next to a couple burned cars.
