Former elevated railway in Greater Boston
The Elevated turned slightly with an elevated station at City Square, then followed Main Street through Charlestown with a station at Thompson Square. Sullivan Square, the original terminal, was a grand arched brick building with multiple streetcar loops. The Sullivan Square Shops, one of the line's two maintenance facilities, was located just north of Sullivan Square. From there, the line turned northeast and crossed the Mystic River on a high bridge, then slowly descended to the ground level Everett station.

Building of the elevated began in 1899 and it opened for revenue service on June 10, 1901. Stations were located at North Union Station (soon renamed as North Station), City Square, and Sullivan Square, with a major maintenance facility at Sullivan Square. The Atlantic Avenue Elevated opened on August 22, 1901, connecting to the Charlestown Elevated east of North Station.

In the 1910s and 1920s, the Boston Elevated Railway (BERy) had plans to extend the Charlestown Elevated to Malden, and the southern portion of this extension, including a drawbridge over the Mystic River, was built in the late 1910s. Everett station was opened in an isolated industrial area just north of the river crossing on March 15, 1919. The Atlantic Avenue Elevated operated only as a shuttle from South Station to the 1912 built North Station platform after 1928, and closed completely on September 30, 1938. A replacement elevated was thus infeasible, while a full length replacement tunnel would have been too expensive. Instead, the Haymarket North Extension project consisted of a tunnel segment from through a new underground stop at , then under the Charles River to a portal near Bunker Hill Community College. From there the extension was built along the Haverhill Line commuter rail right of way, lowering land acquisition difficulties. The Charlestown Elevated was closed at the end of afternoon rush hour service on April 4, 1975, and the Haymarket North Extension opened on April 7. By the end of 1975, only North Station and Sullivan Square stations were standing in their original locations; they were demolished in 1976. Thompson Square station was lowered to the ground for restaurant use, but burned in 1976 before conversion could take place. The footings of the Mystic River bridge, just west of the Route 99 (Alford Street) road bridge, were not removed and remain extant. The elevated supports also remained in the center span of the Charlestown Bridge until it was replaced in 2020. Tower C, which was located at the split between the Charlestown Elevated and the Atlantic Avenue Elevated at the southern end of the Charlestown Bridge, was moved to the Seashore Trolley Museum.
