on what had been the neighborhood of Scollay Square. The northbound tunnel to Haymarket station was rerouted to the west (the southbound tunnel is still original). Scollay Square station was rebuilt as Government Center station, and Adams Square station was closed. Much of the old northbound tunnel was filled in to support the City Hall foundation; another section was turned into a delivery tunnel. Another section was rediscovered by a City Hall employee in 1983; a piece was renovated for use as records storage. In 1971, the original Haymarket station was replaced with a new station just to the south.


Disused southern tunnel branch

The subway in 1897 consisted of a main line under Tremont Street that terminated at Park Street, and two forks to the south. One fork has remained the extant part of the line, which veered westward along Boylston Street, toward the main-line Arlington station, as well as towards Back Bay. The other fork continued south under Tremont Street to the

However, the disused tunnel may become part of a new streetcar line that would partly replace access to rapid transit for southern Metro Boston neighborhoods, that had been severed from MBTA rapid transit service in 1987 with the demolishing of the

Portals

The three original tunnel entrances were in the

). The portal at Kenmore Square was replaced in 1932 when the subway was extended west beyond the Square, to the existing portals on Commonwealth Avenue (the "B" branch) and Beacon Street (the "C" branch), although the top arch of the original portal survives as part of a ventilation shaft. The Fenway portal for the D branch was opened in 1959. The northern portal at Canal Street was replaced in 2004 when the subway was extended beneath North Station to a new portal next to Martha Road. The southern portal at Pleasant Street was abandoned in 1962 following the end of streetcar service through the South End. The portal has since been sealed up and covered by Elliot Norton Park, but the dead-ended tunnel to Boylston survives underground, for a possibility of future re-use (see above).
