the planning of the subway, the city considered recapturing parts of the BMT Jamaica Line, which had been built under the Dual Contracts. This would have created two branches of the Fulton Street Subway east of Broadway Junction. Bellmouths were built into the outer walls of the subway tunnel just east of the Broadway Junction station for a future connection. The IND Fulton Street Line was supposed to be extended farther east into Queens as part of the IND Second System, via an extension of the Fulton Elevated or a new subway. The line would have gone as far as Springfield Boulevard in Queens Village or 229th Street in Cambria Heights, both near the Nassau County border. The line would have also had a spur to the Rockaways. The 1929 Second System plan suggested recapturing and extending the Fulton elevated along Liberty, Brinkerhoff and Hollis Avenues to Springfield Boulevard, near Hempstead Turnpike, Belmont Park, and the Queens Village LIRR Station. The 1939 plan, meanwhile, proposed extending the subway along Pitkin Avenue to Cross Bay Boulevard in South Ozone Park, then along Linden Boulevard to Cambria Heights near the Cross Island Parkway. A spur would have branched off east of Cross Bay Boulevard, turning south to join with the former Rockaway Beach Branch of the Long Island Rail Road (now the IND Rockaway Line). This extended Fulton Street Line would have also facilitated service from the planned Second Avenue Subway via a river tunnel from Lower Manhattan to the then-terminal station at Court Street. In a 1940 plan, which was revised in 1945, the IND Fulton Street Line would connect to the IND Rockaway Line in a similar manner to the 1939 plan, via an extension of the subway under Pitkin Avenue. The line, east of Euclid Avenue, would be 4 tracks, with local stations at 76th Street and 84th Street, and an express station at Cross Bay Boulevard. At Cross Bay Boulevard, a flying junction would let the local tracks cross over to the inside and the express tracks cross over to the outside. The layout would be similar to that of Manhattan's 168th Street station. East of Cross Bay Boulevard, another flying junction would bring a two-track branch over the line to a pair of portals north of Aqueduct–North Conduit Avenue station. Meanwhile, the Fulton Street Line's four tracks would merge into two tracks, and end at 105th Street
