September was operated as Sullivan–Dudley to accommodate summer ferry ridership. Beginning in September 1922, regular service ran Dudley–North Station. On July 22, 1928, a northbound train derailed on the tight curve at Harrison and Beach due to excessive speed and crashed into the abandoned Beach Street station. Two passengers were killed in the wreck – the first time that passengers were killed in an accident on the Main Line Elevated. Regular service resumed on July 24. Boston's waterfront lost importance during the 20th century. The 1904 opening of the East Boston tunnel cut heavily into East Boston ferry ridership, as did the 1934 opening of the Sumner Tunnel. Ferry ridership from elsewhere in Boston Harbor also declined sharply, and many maritime industries moved away from Atlantic Avenue. A 1926 state report on rapid transit expansion recommended the conversion of the Atlantic Avenue Elevated to an elevated highway. The last day of service on the Atlantic Avenue Elevated was September 30, 1938. It sat unused for several years and was torn down in 1942 for scrap metal for World War II. The Central Artery, an elevated highway, was built in the 1950s along Atlantic Avenue and was demolished in 2003 as part of the Big Dig.
