Previous stations For much of the 19th century, the four major northside railroads (the
Fitchburg,
Boston and Lowell (B&L),
Boston and Maine (B&M), and
Eastern) did not share any trackage on the approach to Boston. (Not until
North Union Station in 1893 did they share a depot). For some period after the Fitchburg's Boston terminal replaced its Charlestown terminal in 1848, a
flag stop was made at the Prison Point Bridge. The
Charlestown Elevated section of the
Boston Elevated Railway's
Main Line opened in June 1901, with three elevated stations in Charlestown. The
Thompson Square station was located one-third of a mile east of the current station along Austin Street at Main Street, while the
City Square station was located half a mile south along Rutherford Avenue at Chelsea Street. The elevated was unpopular with many local residents, as it was noisy and blocked out sunlight to Main Street. In 1917, the elevated structure was slated to be replaced with a more permanent subway line along the same Main Street routing, but this project was canceled by the US's entry into World War I.
Community College station In the late 1960s, the MBTA began work on the
Haymarket North Extension project. It included a tunnel segment north from through a new underground stop at
North Station, then under the Charles River to a portal south of the Gilmore Bridge. From there, the extension was built along the
Haverhill Line commuter rail right of way. Community College station was built to replace the two elevated stops nearby in Charlestown. The new route opened to Sullivan Square on April 7, 1975. Routes and , which had terminated at City Square, were not extended to Community College; route 111 was instead extended to Haymarket, while route 112 was rerouted to . In 1987, the MBTA considered construction of a parking garage at the station. The station was not originally
accessible. An elevator to the main platform, reached by a footbridge between the platforms, was constructed as part of the
Big Dig. Bidding took place in 2002. Shaft framework was installed for the unused second platform, but no elevator machinery was installed. The renovations were completed around 2005. The entire Orange Line, including Community College station, was closed from August 19 to September 18, 2022, during maintenance work. The brick surface of the entrance plaza was replaced with concrete in May–June 2024 to improve accessibility. ==References==
