At the south end of the platform, a footbridge connects to the West Squantum Street busway on the east side of the tracks.

[4] MBTA bus routes 210, 211, and 217 stop at a busway at the southern (West Squantum Street) end of the station.

[18][19][20] The station was a single-story Romanesque structure built of brick and Longmeadow brownstone, with a round turret at one corner.

[6] Ridership on the Old Colony system declined further after World War II, and the New Haven decided to abandon the line in the late 1950s.

Emergency subsidies kept the lines open during construction of the Southeast Expressway, but all passenger service to Atlantic, Norfolk Downs and the rest of the former Old Colony system was ended on June 30, 1959.

[1] Shortly after the station opened, the MBTA added a west entrance at the north end to serve the adjacent State Street South office facility.

[28] On September 27, 1991, the MBTA was awarded $32 million in federal funds for accessibility renovations at North Quincy, and for a new station at Riverside.

[29] The work was combined with clearing a two-track railbed on the west side of the station for the restoration of Old Colony Lines commuter rail service.

[33] In February 2016, three bidders submitted proposals for mixed-use transit-oriented development to be built on the Hancock Street lot, with a new garage to replace lost parking spaces.

[36] Shortly before construction was expected to begin, a local carpenters union petitioned the state to force a public bidding process for the garage because it will be operated by the MBTA.

In April 2018, Massachusetts Attorney General Maura Healey ruled that the MBTA or the developers were legally required to publicly bid for the garage construction.
