Further revision of the plan and more studies followed. By 1939, construction had been postponed indefinitely, with only a short length being completed above the Second Avenue station. The Second Avenue Line was relegated to "proposed" status, and was number 14 on the Board of Transportation's list of important transportation projects. The line was cut to two tracks with single northern branch through Throggs Neck, Bronx, a connection to the BMT Broadway Line in Manhattan, and a continuation south onto the IND Fulton Street Line in Brooklyn via that line's Court Street station. The subway's projected cost went up to US$249 million (equivalent to $ in ). The United States' entry into World War II in 1941 halted all but the most urgent public works projects, delaying the Second Avenue Line once again.
