Cambridge Seven worked closely with engineers, government agencies and community representatives to construct Porter Square Station, which serves both the rapid transit and the commuter rail systems. The goal was to create for this neighborhood a sense of place, and a sense of destination. This visually impressive station is situated 105 feet below ground under the heavily-traveled Massachusetts Avenue. A sky-lit mezzanine level with food concession, newspaper vendors and a waiting area breaks the long escalator descent down to the subway platform. The public art, selected and coordinated by Cambridge Seven, enhances the plaza, the mezzanine level, as well as the escalators.
