Commonwealth Avenue is a roadway in the Esplanade neighborhood of Boston in 2287.


The avenue served as one of Boston's major thoroughfares before the Great War, connecting the Fens with Boston Common.[1]


The avenue spans the southern edge of the Esplanade neighborhood, parallel to the riverfront Storrow Drive. It runs from the Holy Mission Congregation church in the west to Boston Common in the east. The thoroughfare is divided by a wide median planted with trees, and is flanked by pre-War mansions.[2]


Commonwealth Avenue appears only in Fallout 4.

    "Technically part of the Back Bay Neighborhood, the Charles River Esplanade is comprised of the remains of a park, some waterfront mansions still exhibiting the faded grandeur of times gone by, and one of the main thoroughfares of Boston — Commonwealth Avenue."
