The '''7 Subway Extension''' is a [[Rapid transit|subway]] extension of the [[New York City Subway]]'s [[IRT Flushing Line]], which is served by the {{NYCS|7}} local and {{NYCS|7d|&lt;7&gt;}} express services. The extension stretches {{convert|1.5|mi|km}} southwest from its previous terminus at [[Times Square (IRT Flushing Line)|Times Square]], at Seventh Avenue and 41st Street, to [[34th Street–Hudson Yards (IRT Flushing Line)|one new station]] at 34th Street and Eleventh Avenue. A second station at [[10th Avenue (IRT Flushing Line)|10th Avenue and 41st Street]] was dropped from the plans in October 2007. The entirety of the extension is located within the [[New York City]] borough of [[Manhattan]]. The extension, a key part of the [[Hudson Yards Redevelopment Project]], is expected to bring business and entertainment into the area, as well as aid redevelopment of nearby [[Chelsea, Manhattan|Chelsea]] and [[Hell's Kitchen, Manhattan|Hell's Kitchen]], located around the [[Long Island Rail Road]]'s [[West Side Yard]]. The extension also serves the nearby [[Jacob K. Javits Convention Center]].

The project was originally proposed in 2005 as part of the Hudson Yards project, which included the failed attempt to build the [[West Side Stadium]] for the [[New York Jets]] and [[New York City 2012 Olympic bid|the city's bid]] for the [[2012 Summer Olympics]]. Although the stadium plan was rejected by the state legislature, the rest of the [[Hudson Yards (development)|Hudson Yards]] rail yard development, including the 7 Subway Extension, went forward. Construction on the extension started in 2007.

The extension's opening was postponed multiple times from its original target of December 2013. The delays were attributed to a variety of problems, mostly involving the {{convert|170|ft|m|adj=mid|-long}} [[incline elevator]]s that were custom-designed for the new station. The extension finally opened to the public on September 13, 2015.

Proposals to extend the transit system to the Far West Side to support massive redevelopment were floated as early as 1969, when the [[New York City Planning Commission]]'s (CPC's) master plan proposed to expand midtown westward along a 48th Street transit line to replace what the plan described as "blocks of antiquated and deteriorating structures of every sort" between Eighth and Twelfth avenues.<ref>{{cite web | last=Stern | first=Michael | title=6TH AND LAST PART OF MASTER PLAN ON CITY RELEASED; Volume on Manhattan Urges Building of Offices Along 48th St. Transit Line WESTWARD PATTERN SET Condemnation of Big Tracts Intended to Insure Public Use of Some of Area | website=The New York Times | date=December 8, 1970 | url=https://www.nytimes.com/1970/12/08/archives/6th-and-last-part-of-master-plan-on-city-released-volume-on.html | access-date=September 20, 2015}}</ref> That proposal for the West 40s and 50s failed after voters rejected a state bond issue that would have financed the proposed new east–west transit line or "people mover."<ref>{{cite news |first=Richard |last=Witkin |url=https://www.nytimes.com/1971/11/04/archives/state-will-cancel-some-road-projects.html |title=State Will Cancel Some Road Projects |work=The New York Times |date=November 4, 1971}}</ref> Subsequently, attention shifted to the West 30s and the [[IRT Flushing Line]].

In December 2001, the [[New York City Department of City Planning]] issued a study entitled ''Far West Midtown: A Framework for Development'' that recommended zoning changes and an extension of the Flushing Line to revitalize Far West Midtown. The [[government of New York City]] devised a rezoning plan for the Hudson Yards area and proposed two new subway stations to serve that area, with the extension of the subway to be financed by $2.1 billion of city-issued bonds. The project also included an expansion of the [[Javits Center]] and a proposed [[West Side Stadium]], the latter of which was to serve as the venue of the opening and closing ceremonies and track and field events in the [[New York City bid for the 2012 Summer Olympics]].<ref>{{cite web |year=2004 |url=https://www.nyc.gov/assets/planning/download/pdf/plans/hudson-yards/hy_chap1_t_fgeis_final.pdf |title=No. 7 Subway Extension—Hudson Yards Rezoning and Development Program FGEIS |publisher=nyc.gov |pages=1-1, 1-11, 1-14, 1-15 |access-date=March 11, 2025}}</ref><ref name=hydc2>{{cite web |url=http://www.hydc.org/html/project/subway.shtml |title=No. 7 Subway Extension |author=<!--Staff writer(s); no by-line.--> |website=Hudson Yards Development Corporation |access-date=July 3, 2013 |archive-url=https://web.archive.org/web/20150209053224/http://www.hydc.org/html/project/subway.shtml |archive-date=February 9, 2015 |url-status=dead }}</ref><ref name=hp20130207>{{cite news |url=https://www.huffingtonpost.com/2013/02/07/nyc-subway-underground-rail-second-avenue-subway_n_2637601.html |title=NYC Transit Projects: East Side Access, Second Avenue Subway, and 7 Train Extension |last1=Dobnik |first1=Verena |date=February 7, 2013 |website=Huffington Post |access-date=July 24, 2013 |url-status=dead |archive-url=https://web.archive.org/web/20131021183340/https://www.huffingtonpost.com/2013/02/07/nyc-subway-underground-rail-second-avenue-subway_n_2637601.html |archive-date=October 21, 2013}}</ref> The City wanted to get funding before July 2005, at which time the [[International Olympic Committee]] would vote on funding.

In October 2007, the [[Metropolitan Transportation Authority|Metropolitan Transportation Authority (MTA)]] awarded a $1.145 billion contract to build {{convert|7000|ft|m}} of twin-tube tunnel from the 7 train's then-terminus at Times Square to the then-planned shell of the 34th Street–Hudson Yards station.

The use of inclined elevators was intended to provide wheelchair-using patrons with a shorter, easier path to the train platform, as well as to reduce tunneling costs.<ref name="rising nytimes"/> The two elevators were manufactured by Maspero Elevatori, in [[Appiano Gentile]], Italy, using a controller made on Long Island, speed governors made in [[Ohio]], and buttons and other parts in Queens.<ref name="rising nytimes"/> The software for the elevator was written in the United States. Maspero Elevatori assembled the elevators in Italy, and they failed an operational test there, prior to being shipped to the United States.<ref name="rising nytimes"/> The MTA said the manufacturer chose to use American subcontractors in place of local Italian suppliers after reading the specifications the transit agency submitted.

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 [[Regional Plan Association]], in its Fourth Plan in 2017, proposed extending the 7 subway down the tail tracks and the Hudson waterfront to a new station at 14th Street and Tenth Avenue, with an intermediate stop at 23rd Street and Eleventh Avenue. If constructed, the new Tenth Avenue station would feature a pedestrian connection to the [[14th Street/Eighth Avenue station]], with transfers to the {{NYCS trains|14th Eighth}}, and the tunnel would be configured to allow for a New Jersey extension.<ref name="Fourth Regional Plan - Regional Plan Association">{{cite web|title=Fourth Regional Plan - Regional Plan Association|url=http://fourthplan.org/|publisher=Regional Plan Association|date=November 2017 |access-date=January 22, 2022}}</ref>

==Awards and innovations==
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 machine]]s (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."<ref>{{cite web |url=http://www.tunnelingonline.com/new-york-state-society-of-professional-engineers-award/ |title=New York State Society of Professional Engineers Recognizes No. 7 Line Project |date=July 3, 2013 |website=Tunnel Business Magazine |access-date=August 20, 2013}}</ref> While the extension extends {{convert|1|mi|km}}, the tunnels are actually {{convert|1.5|mi|km}} long.<ref>{{cite web |url=http://web.mta.info/capital/future/extension.php |work=MTA.info |access-date=November 10, 2013 |title=7 Line Extension}}</ref>
