East Side Access is a public-works project being undertaken by the Metropolitan Transportation Authority (MTA) in New York City. It is designed to bring the Long Island Rail Road into a new East Side station to be built below, and incorporated into, Grand Central Terminal. The new terminal is expected to be operational by between 2019 and September 2023.[1]

Description[edit]

Extending between Sunnyside, Queens, and Grand Central, the project will route the LIRR from its Main Line through new track connections in Sunnyside Yard and through the lower level of the existing 63rd Street Tunnel under the East River. In Manhattan, a new tunnel will begin at the western end of the 63rd Street Tunnel at Second Avenue, curving south under Park Avenue and entering a new LIRR terminal beneath Grand Central.

Current plans call for 24-trains-per-hour service to Grand Central during peak morning hours, with an estimated 162,000 passenger trips to and from Grand Central on an average weekday. Connections to AirTrain JFK at Jamaica Station in Jamaica, Queens, will facilitate travel to John F. Kennedy International Airport from the East Side of Manhattan. However, the tunnels of the East Side Access can only be used by M3, M7, and M9 railcars due to a height restriction created when the 63rd Street Tunnel was first built. C3 railcars and EMD DE30AC and DM30AC locomotives will not be able to use the tunnels.[2]

A new LIRR train station in Sunnyside at Queens Boulevard and Skillman Avenue[3] along the Northeast Corridor (which the LIRR uses to get into Pennsylvania Station) will provide one-stop access for area residents to Midtown Manhattan.[4] The station may spur economic development and growth in Long Island City.[citation needed]

The project's estimated cost has increased from $3 billion in 1998[citation needed] to $6.3 billion in 2006, $8.4 billion in 2012, and $10.8 billion in 2014.[5] Though construction work is ongoing, the completion date for the project has been continually pushed back by the MTA. Once planned to be operational by 2013, the MTA has pushed back the completion date several times, most recently to September 2023,[1] although the terminal can open as soon as 2019.[6][7][8][9] With the seven-year delay in the completion date and the 180% cost increase to $8.4 billion, the U.S. DoT Inspector General wants an audit done on the project.[10]

The project is likely to increase passenger loads on the already overcrowded IRT Lexington Avenue Line, the sole East Side subway line, and on surface bus routes on the East Side. The project has, therefore, focused attention on the long-delayed Second Avenue Subway along the far East Side of Manhattan, which is again under construction and is expected to relieve north/south commuting pressure. At the same time, the project will reduce the load on morning, northbound rush-hour E train service between Pennsylvania Station and Midtown East.[citation needed]

History[edit]

Origins[edit]

Construction of the line to Grand Central was begun in November 1969 as the lower level of a cut-and-cover project to build the New York City Subway's 63rd Street Line. The MTA's contractor floated premanufactured four-chamber tunnel boxes into place in the East River and sank them to create the East River crossings for the subway and the LIRR. After a long delay caused by New York City's fiscal collapse of the 1970s, the 63rd Street subway line and LIRR tunnel were completed as far as 21st Street in Long Island City, Queens. Between 1995 and 2001, the 63rd Street subway line was connected to the Queens Boulevard train corridor, and the LIRR tunnel was extended under 41st Avenue in Queens to the west side of Northern Boulevard in Queens. The western end of this tunnel sat under Second Avenue at 63rd Street.

Construction[edit]

ESA Project Information Center

The project represents the construction effort to complete the line to Grand Central. After voters in New York approved a bond issue to provide state funds to the project, the federal government committed to provide $2.6 billion to help build the project by signing a Full Funding Grant Agreement in December 2006.[11] The construction contract for a one-mile (two-kilometer) tunnel in Manhattan west and southward from the dormant lower level of the 63rd Street rail tunnel to the new station beneath Grand Central was awarded on July 13, 2006, to Dragados/Judlau, a joint American–Spanish venture (the American company is located in College Point, Queens).[12] The total contract award is $430 million,[12] and is using two large tunneling devices owned by the Spanish firm.[13]

Dragados/Judlau created a launch chamber for tunnel-boring machines (TBM) under Second Avenue at 63rd Street using a controlled drill-and-blast method, then assembled and launched each 640-ton machine. The first TBM was launched west and southbound from the 63rd Street tunnel in September 2007 and reached Grand Central in July 2008.[14] The second machine began boring a parallel tunnel in December 2007 and had completed its tunnel at 37th Street on September 30, 2008.[15][16] Geocomp Corporation was hired to monitor the boring, using a battery of instruments to record vibration, ground settlement and any tilting or drift suffered by the TBM. The instruments include inclinometers, extensometers, seismographs, observation wells, dynamic strain gauges, tilt meters and automated motorized total stations (AMTS) with prismatic targets.[17] The next step in construction is to back the TBMs out of the tunnels and cast-in-place concrete sections placed to create the lining.[18] Each tunnel will be 22 feet (7 metres) in diameter and carry trains 140 feet (43 metres) beneath street level.[19] The TBMs bored an average of 50 feet (15 metres) per day. Cross-connections between the tunnels are being created under Park Avenue, between 49th and 51st Streets, by controlled drill-and-blast; the work began in mid-July 2008 and was expected to require between six and eight months to complete.[14]

As of June 2011, eight station tunnels under Grand Central – where trains will berth at platforms – were fully bored, and station excavation was still underway.[20]

Emergency exit under construction in Sunnyside Yard

In Queens, Pile Foundation Construction Company is building an $83 million open-cut and deck project, which is extending the tracks under Northern Boulevard into Sunnyside Yard, and creating an area that serves as both the launch chamber for soft-bore Queens tunnels, connecting the 63rd Street line to the main LIRR branches, and an interlocking and emergency exit and venting facility.[21][22] Perini Corporation was awarded a $161 million contract to reconfigure Harold Interlocking, increasing its capacity to accommodate Grand Central-bound trains and accept new yard lead tracks to allow trains to enter the storage yards. On February 15, 2008, the MTA awarded Dragados-Judlau a $499 million contract to excavate the LIRR station and track wye caverns. On September 10, 2009, the MTA awarded Yonkers Contracting Company a $40.76 million contract to demolish a building at 44th Street and construct a ventilation plant and station entrance. On September 28, 2009, the MTA awarded Granite-Traylor-Frontiere Joint Venture a $659.2 million contract to employ two 500-ton slurry TBMs to create the tunnels which will connect the LIRR main line and the Port Washington Branch to the tunnel under 41st Avenue (the 63rd Street tunnel).[23][24] Four tunnels, with precast concrete liners, will total two miles (three kilometers) in length. In March 2011, the MTA announced that these two TBMs would begin tunneling in April 2011.[25][26]

On December 22, 2011, breakthrough was achieved in Tunnel "A" of the four Queens tunnel drives from the 63rd Street tunnel bellmouth.[27] On July 25, 2012, all four Queens tunnel drives were complete.[28]

Controversy[edit]

Given the massive size of the project, the plan has aroused concerns and opposition. For example, in 2005, businesses and Catholic Archbishop, Cardinal Edward Egan, began to express concerns about the tunneling process. Egan in particular was concerned about the impact on St. Patrick's Cathedral, which faces Fifth Avenue with its back on Madison Avenue north of 50th Street. The project is proposing that an air vent be placed south of 50th Street and east of Madison Avenue, just outside the existing train shed.[29] The contract for the 50th Street air vent was awarded by the end of 2011, and as of May 2012 construction of the vent was underway.[30]

The project's extensive delays and cost overruns have led a leading transit blogger to call the project a "disaster."[31]
