Second Ave Subway (SAS)

The Second Avenue Subway (officially the IND Second Avenue Line; abbreviated to SAS) is a New York City Subway line that has been under discussion since the 1910s. It runs under Second Avenue on the East Side of Manhattan. The first phase of this new line will open on January 1, 2017, extending the Q train to 96th Street and Second Avenue, serving a projected 200,000 daily riders at four new stations. Some N trains will provide additional service on the line during rush hours. Phase one runs between 96th Street and the 63rd Street Lines, connecting to the BMT Broadway Line and the rest of the subway system. The full Second Avenue Line, if and when funded, would be built in three additional phases, allowing portions to open before the entire line is completed. When completed, it would be served by a proposed T train between 125th Street and 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.
