亨廷顿大道
The first section of the Tremont Street subway opened on September 1, 1897. Among the lines immediately routed into the subway using the Public Garden incline were the Cypress Street via Huntington Avenue and Jamaica Plain crosstown via Huntington Avenue lines. The southern subway section to the Pleasant Street incline opened on September 30, and Jamaica Plain cars via Tremont Street were routed into the subway. Reservoir service via Huntington Avenue was added to the subway on November 8. Longwood Avenue cars and Lake Street via Huntington Avenue cars soon used the subway as well. Other early services also used Huntington Avenue east of Massachusetts Avenue, including a Forest Hills–Park Street route via Washington Street (introduced on November 1, 1898) and a Humboldt Avenue–East Boston Ferries route.
