The East Side Access project is based on regional planning proposals that were first brought up in the 1950s. In March 1954, the New York City Transit Authority (NYCTA) issued a $658 million construction program. The proposal included a tunnel for the Second Avenue Subway, which would cross the East River between 76th Street in Manhattan and Astoria in Queens before continuing onto the Long Island Rail Road (LIRR)'s Main Line in Queens. The 76th Street tunnel proposal resurfaced in 1963, though the location of the tunnel was changed several times thereafter. In 1965, the NYCTA finally decided to construct the subway tunnel at 63rd Street.
