The Second Avenue Subway (internally the IND Second Avenue Line; abbreviated to SAS) is a New York City Subway line that runs under Second Avenue on the East Side of Manhattan. The first phase of this new line opened on January 1, 2017, connecting three new stations between 96th Street and the 63rd Street Lines to the BMT Broadway Line and the rest of the subway system. The full Second Avenue Line, if and when funded, is to be built in three more phases that will eventually connect 125th Street to Hanover Square. The proposed full line would be 8.5 miles (13.7 km) long with 16 stations and a projected daily ridership of 560,000, costing more than $17 billion.
The line was originally proposed in 1919 as part of a massive expansion of what would become the Independent Subway System (IND). As several factors caused this proposals and subsequent ones to be canceled, parallel elevated lines along Second Avenue and Third Avenue were respectively demolished in 1942 and 1955 in anticipation for the Second Avenue Subway being built to replace them. Construction on the Second Avenue Line initially began in 1972 as part of the Program for Action, but was halted in 1975 because of the city's fiscal crisis, with only a few short segments of tunnels having been completed. Work on the line restarted in April 2007 following the development of a financially secure construction plan. The first phase of the line, consisting of three newly-built stations and two miles (3.2 km) of tunnel, cost $4.45 billion. A 1.5-mile (2.4 km), $6 billion second phase is in planning and is expected to open by 2027–2029.
