A plan similar to the Chrystie Street Connection was as part of the Second Avenue Subway (SAS) under the Board of Transportation's 1944-1948 Capital Program, with connections from the 2nd Avenue line to the BMT Nassau Street Line, the Williamsburg and Manhattan Bridges, as well as a new station at Grand and Chrystie Streets. This plan would have allowed service from Grand Street to run south to Chambers and Broad Streets on the Nassau Street line, providing an additional East River crossing via the Montague Street Tunnel. In 1954, the modern Chrystie Street plans were introduced as part of a request by the Transit Authority (TA) for $172 million in capital transit improvement funds.
