The 7 Subway Extension — Hudson Yards Rezoning and Development Program is the plan to extend the IRT Flushing Line of the New York City Subway, which carries the 7 local and <7> express services, further westward into the New York City borough of Manhattan.[2] The extension stretches a total of 1 mile (1.6 km) from its current terminus at Times Square to a new western terminus at 34th Street and 11th Avenue.[2] However, the tunnels are actually 1.5 miles (2.4 km) long.[3] A second station at 10th Avenue – 41st Street was dropped from the plans in October 2007, but could be restored if funding can be found.[4] The extension's opening had been delayed to June 2014, with the rest of the 34th Street station to open at the end of 2015.[5][6] Michael Horodniceanu, chief of MTA Construction Company, told The New York Times that complications in the installation of the inclined elevator would likely cause a further delay of about three months, bringing the opening date to very late summer or early fall of 2014.[7] Further complications in February 2014 brought the projected date of the opening to November 2014.[1]

The extension is a key part of the Hudson Yards Redevelopment Project, and is expected to bring business and entertainment into the area; the project is intended to aid redevelopment of Hell's Kitchen around the West Side Yard of the Long Island Rail Road.[8] It was originally proposed as part of the failed attempt to build the West Side Stadium for the New York Jets and the city's bid for the 2012 Summer Olympics.[8][9] Although the stadium plan was rejected by city and state planning agencies, the 7 subway extension plan received approval to move ahead, as New York political leaders wanted to see the warehouse district west of Eighth Avenue and north of 34th Street redeveloped, and a subway service would be an essential part of that effort. The extension would also serve the Jacob K. Javits Convention Center, renovated in 2006.[10] The New York State Society of Professional Engineers awarded the first construction phase, "Running Tunnels and Underground Structures," its 2013 Construction Project of the Year. According to the society, the project team won the award "for outstanding professional engineering efforts in developing creative solutions and innovative technologies in construction of an infrastructure project. The No. 7 project used the first double-shielded tunnel boring machines (TBMs) to tunnel under New York City while placing precast concrete segments to form the tunnels’ walls. For the first time in the world, a ground freezing method was used to harden soil to act as rock to allow TBMs to maintain proper course while boring and placing the tunnel liners."[11]

Construction progress[edit]

In October 2007, the Metropolitan Transportation Authority (MTA) awarded a $1.145 billion contract to build 7,000 feet (2,100 m) of twin-tube tunnel, from the current 7 train terminus at Times Square to the then-planned shell of the 34th Street station, to S3, a joint venture of J.F. Shea, Skanska USA Civil, and Schiavone.[4][12][13] Richard Dattner and Partners, Architects, designed the Jacob Javits Convention Center station.[14] After excavating the new terminal's shell and creating the first 1,000 feet (300 m) of tunnel using the drill-and-blast method, S3 placed two tunnel-boring machines (TBMs) in the ground to dig the remaining 6,000 feet (1,800 m); as it dug, each TBM placed precast concrete liner segments to create the tunnel interior.

In September 2007, it was announced that the new station would feature platform screen doors.[15] The station (along with the new South Ferry station on the IRT Broadway – Seventh Avenue Line) will include special air-cooling systems to reduce the temperature along platforms.[16]

On December 3, 2007, the MTA conducted a ceremony at the Times Square subway station marking the launch of construction of the 7 train extension. The contractor began excavating the station cavern adjacent to the Javits Convention Center. MTA posted a construction update with photographs on its website in November 2008, showing substantial progress.[17]

Mayor Michael Bloomberg's December 12, 2006, address to the New York League of Conservation Voters noted that in November 2006, the government began issuing bonds to fund the extension of the 7 subway to Eleventh Avenue and 34th Street.[18] The $2 Billion 7 train subway extension is being funded with New York City funds from municipal Tax Increment Financing (TIF) bond sales that are expected to be repaid with property tax revenues from future developments in areas served by the extension.[19]

One physical hindrance to the construction of the extension was the lower-level platform at 42nd Street – Port Authority Bus Terminal on the IND Eighth Avenue Line. The abandoned platform was partially razed, to allow the 7 train extension to be built.[20]

In June 2008, construction on the tunnels began along Eleventh Avenue in Manhattan. In February 2009, S3 lowered the first of two tunnel-boring machine into a giant shaft at the corner of 25th Street and Eleventh Avenue.[21] The two boring machines dug parallel 7,100-foot (2,200 m) long tunnels north along Eleventh Avenue to the current terminus of the 7 service at 41st Street and Times Square. On December 21, 2009, the MTA said that a tunnel-boring machine broke through the 34th Street station cavern wall.[22] Both tunnel-boring machines were scheduled to finish the required tunneling in the spring of 2010.[23]

In June 2009, the MTA completed excavation of a 150-foot (46 m) long cavern within the basement of the Port Authority Bus Terminal, which will form part of the eastern end of the new extension and connect it to the Times Square station. The cavern lies just below the bus entrance ramp to the terminal's lower level. In June 2010, one of the TBMs completed its tunnel at the cavern; the second TBM broke through the wall of the cavern on July 15, 2010, completing its tunneling operation. The TBMs were partially disassembled and backed up to the 25th Street shaft, where they were lifted out.[24][25][26] In April 2011, the MTA announced that the contract covering the tunnels, the 34th Street station mezzanine and passenger platform was 85% complete, and that the systems contract, covering mechanical and electrical systems, electric power, lighting and train tracks would be awarded by July 2011. A second entrance to the station is planned.[27] In May 2012, the MTA announced that the extension, now 65% complete, had received the installation of the first set of rails.[28]

On August 21, 2013, the MTA announced that the 7 subway extension was 90% complete.[29]

On December 20, 2013, Mayor Michael Bloomberg took a ceremonial ride on a train to the new terminal, celebrating a part of his legacy as Mayor.[30][31]

The 34th Street station, which is under construction as of December 2013, is at the intersection of 11th Avenue and 34th Street. It will be the only new station on the extension, and is expected to open in November 2014. The MTA says that the new station will "make it possible for new housing, restaurants and entertainment to grow" in the surrounding neighborhoods, including Hell's Kitchen and Chelsea.[32]

Proposed 10th Avenue station[edit]

Although a new station at 10th Avenue and 41st Street was part of the original plan, the intermediate station was eliminated in October 2007 due to cost overruns, leaving the terminal station at Eleventh Avenue and 34th Street as the only new station on the extension. The MTA indicated that the 10th Avenue station could be included in the project if funding were found.[4] The station was not included in the original (2007) contract award, but was listed as a $450 million option. In late December 2007, reports indicated that the postponed station might be partially built if the City of New York and the MTA agreed on the additional financing for the station shell.[33] In February 2009, the MTA announced that it would build the station if the agency received sufficient funds from the federal economic stimulus package.[34] In June 2010, the city announced it was seeking funding to assess the feasibility of constructing the station at a later date using a two-platform, two-entrance model without an underground connecting passage.[35][36][37][38][39]

Proposed New Jersey Extension[edit]

On November 16, 2010, The New York Times reported that Mayor Michael Bloomberg's administration had been working on a plan to extend the 7 service across the Hudson River to Hoboken and continue to Secaucus Junction in New Jersey, where it would connect with most New Jersey Transit commuter lines. It would offer New Jersey commuters a direct route to Grand Central Terminal on the East Side of Manhattan and connections to most other New York City subway routes.[40]

If opened, the extension would take the New York City Subway outside the state's borders for the first time. The plan would replace the Access to the Region's Core (ARC) tunnel, which was canceled by New Jersey Governor Chris Christie in October 2010.[41]

On February 2, 2011 the city's Economic Development Corporation voted to budget up to $250,000 for a feasibility study of a tunnel for the subway line extension. Parsons Brinckerhoff, a major engineering firm that had been working on the ARC tunnel, carried out the study.[42][43] The report was released in April 2013.[44][45] The proposal includes the construction of the in-fill station at 10th Avenue, tunnels running along the path of the ARC tunnel, and a multi-level multi-modal addition to Secaucus Junction. A widening of the right-of way of the Northeast Corridor was considered.[46]

The New York Post has reported that the Flushing line extension to Secaucus will have a formal proposal made by Mayor Bloomberg around the end of 2012. New Jersey Governor Chris Christie and the Port Authority are on record as supporting the plan, along with splitting the estimated US$10 billion cost if it is officially approved.[47]

A subway extension would cost less than the ARC tunnel, as it would start at the planned station at Eleventh Avenue and go west, avoiding the expensive tunnel boring work east to Herald Square and the complex station deep underground there. However, travel times into Manhattan might be longer than under the original ARC proposal, because riders would need to transfer to the subway from New Jersey Transit trains at Secaucus. Additionally, because NJT trains would continue to or from Penn Station, the key goal of reduced tunnel congestion between New Jersey and New York would not be achieved. On the other hand, as Governor Christie said "It would actually connect us to the east side of Manhattan, like we always wanted to..."[48] Bloomberg had yet to meet with New York Governor-elect Andrew Cuomo, and the project, which could require five additional years to develop, would not be automatically entitled to the federal funding allotted to the ARC tunnel.[49][50][51][52]

Amtrak's February 2011 announcement of the Gateway Project includes a proposal to extend the 7 service three blocks east of Eleventh Avenue to New York Penn Station, instead of five miles west to Secaucus.[53] Gateway, under auspices of Amtrak, would include a high-speed rail right-of way from Newark Penn to New York Penn and provide more capacity on New Jersey Transit rail operations. US Congress allocated $15 million for studies for the project in November 2011. It is likely the two projects, Gateway and the subway extension, will be in competition for funding.[54]

In April 2012, citing budget considerations, the director of the MTA, Joe Lhota, said that it was doubtful the extension would be built in the foreseeable future, suggesting that the Gateway Project was a much more likely solution to congestion at Hudson River crossings.[55] However, a feasibility study commissioned by the city and released in April 2013 revived hope for the project, with Mayor Bloomberg saying "Extending the 7 train to Secaucus is a promising potential solution ... and is deserving of serious consideration."[56][57]

In a November 2013 Daily News opinion article, the president of the Real Estate Board of New York and the chairman of Edison Properties called for the line to be extended to Secaucus in tunnels to be shared with the Gateway Project.[58] Later in November 2013 the New Jersey Assembly passed a Resolution 168[59] supporting the extension of the line to Hoboken and Secaucus.[60]
