Tremont Street Subway - Entrances

Entrances

The original entrances were in the Public Garden, at North Station/Canal Street, and at Pleasant Street. These portals were replaced and abandoned as the subway was extended. The Public Garden portal was replaced in 1914 with two portals, one located in the middle of Boylston Street adjacent to the old portal, and one at the west end of the Boylston Street Subway, just east of Kenmore Square. The Boylston Street portal was abandoned in 1941 when the Huntington Avenue Subway was opened (with a portal at Northeastern University). The portal at Kenmore Square was replaced in 1932 when the subway was extended below the square to the existing portals on Commonwealth Avenue (the "B" line) and Beacon Street (the "C" line), although the top arch of the portal survives as part of a ventilation shaft. The Fenway portal for the "D" line was opened in 1959.

The 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 portal at Pleasant Street was abandoned in 1962 following the end of streetcar service through the South End. For the last several months service consisted of only a shuttle between the top of the portal and Boylston Station. The portal has since been sealed up, but the tunnel to Boylston survives.
