The massive terminal served numerous streetcar lines as well as elevated trains.

The modern station opened in May 1975 as part of the Haymarket North Extension, which replaced the Charlestown Elevated; the old terminal was demolished the next year. Sullivan Square station was made accessiblein the 1990s, and the busways were reconfigured in 2018–2019.
