The Pleasant Street Incline or Pleasant Street Portal was the southern access point for the Tremont Street Subway in Boston, Massachusetts, which became part of the Green Line after the incline was closed. The portal and the section of tunnel connecting it to Boylston served Green Line streetcars from 1897 to 1901, Main Line Elevated (Orange Line) trains from 1901 to 1908, and streetcars again from 1908 to 1962. The Pleasant Street Incline is now abandoned, but plans have been floated at various times to reuse it.
The incline opened on 1 October 1897, one month after the first section of the Tremont Street Subway, allowing streetcar lines from Roxbury, Dorchester, and points south to operate via the subway. The new tunnel stretched from the outer tracks at Boylston south under Tremont Street, with a four-track portal in the triangle bounded by Tremont Street, Pleasant Street (later part of Broadway), and Shawmut Avenue. The tunnel carried two tracks, splitting into four tracks at a flying junction near the portal, with the northbound (western) track going over the southbound (eastern) track. The two western tracks continued down Tremont Street, while the eastern tracks turned east on Pleasant Street via Broadway to City Point in South Boston.
