The East River Tunnels are four single-track railroad passenger service tunnels that extend from the eastern end of Pennsylvania Station under 32nd and 33rd Streets in Manhattan and cross the East River to Long Island City in Queens. The tracks carry Long Island Rail Road (LIRR) and Amtrak trains travelling to and from Penn Station and points to the north and east. The tracks also carry New Jersey Transit trains deadheading to Sunnyside Yard. They are part of Amtrak's Northeast Corridor, used by trains traveling between New York City and New England via the Hell Gate Bridge. History Construction The tunnels were built in the first decade of the 20th century as part of the New York Tunnel Extension. The original plan for the extension which was published in June 1901, called for the construction of a bridge across Hudson River between 45th and 50th Streets in Manhattan, as well as two closely spaced terminals for the LIRR and Pennsylvania Railroad (PRR). This would allow passengers to travel between Long Island and New Jersey without having to switch trains; at the time, LIRR trains ran to Long Island City, where passengers took ferries across the East River to the 34th Street Ferry Terminal in Manhattan. As part of the extension, the LIRR became a subsidiary of the Pennsylvania Railroad. In December 1901, because of the high cost of building a bridge, the plans were modified so that the PRR would construct the North River Tunnels under the Hudson River. The New York Tunnel Extension quickly gained opposition from the New York City Board of Rapid Transit Commissioners, who objected that they would not have jurisdiction over the new tunnels, as well as from the Interborough Rapid Transit Company, which saw the New York Tunnel Extension as a potential competitor to its as-yet-incomplete rapid transit service. The project was approved by the New York City Board of Aldermen in December 1902, on a 41-36 vote. The North and East River Tunnels were to built under the riverbed of their respective rivers. The PRR and LIRR lines would converge at New York Penn Station, an expansive Beaux-Arts edifice between 31st and 33rd Streets in Manhattan. The entire project was expected to cost over $100 million. The contract for building the East River Tunnels was awarded to S. Pearson & Son in 1903. Originally, the tunnel would have comprised two tubes, but this
