Unlike other NYC projects that continue to face more and more delays, the 7 Line extension is making great time, and is expected to open in just another 12-18 months. The new subway extension will jut across Midtown, connecting the far reaches of Hell’s Kitchen with Grand Central Station and Queens. Since digging an elevator shaft right at 11th Avenue was not an option, the MTA turned to designing an incline elevator. Inside the station, an overhead oval will act as a skylight, bringing a burst of sunlight to commuters below, and be painted in a deep blue hue to double as a decorative element. The stair shaftway that connects the mezzanine to the platform will help circulate air in the station, which will be naturally cooled with an air tempered design. The MTA anticipates that the new 7 Line station will be the most used station in 2020, bringing commuters to the West Side, and to an array of retail spaces such as Coach and L’Oreal on site.

The new station is air tempered, and will be several degrees cooler than the outside summer air.
The new Line station is the only station with 2 high rise inclined elevators, and will bring passengers 125ft below ground.
The new station is the MTA's 469th subway station, the first addition to the subway system in 26 years.
The culmination of 8 years of construction, the subway extension makes it possible for new housing, office buildings, restaurants, entertainment and other commercial establishments to grow on the Far West Side in an area now being referred to as Hudson Yards.
The new subway terminal improves service reliability for all riders of the Line in Queens and Manhattan by providing additional storage space for trains.
The 34 St-Hudson Yards Station has three public floors — the upper mezzanine (27.6 feet below street level), the lower mezzanine (109 feet below street level) and the platform level (125 feet below street level).
Access from the street level to the upper mezzanine at the main entrance is provided by four low-rise escalators and two staircases. Among the station’s modern amenities, the platform level is air-tempered, maintaining a year-round temperature between 72 and 78 degrees Fahrenheit. The station also features 12 Help Point Intercoms that allow customers to communicate with the station agent or the Rail Control Center in the case of an emergency. Eight On-the-Go screens, cell phone connectivity and Wi-Fi will be added in the near future, all of which will provide a new level of service and communications for customers. Throughout its operation, as each TBM progressed with mining it also placed pre-manufactured consecutive sets of concrete liner rings in its wake, to form the finished tunnel.


The Line Subway Extension is considered to be the first instance of a TBM mining through a substantial length of artificially frozen earth in New York City. The operation took about 10 weeks to reach a frozen state where mining could commence, and was kept frozen for an additional 3 months until the two TBMs had passed through the area and lined the tunnels. In order to make way for the TBMs to connect with existing tail tracks from Times Square, the construction team had to underpin the 8th Avenue line at the Port Authority Bus Terminal. The new station at 34th Street and 11th Avenue is the third station in the New York City subway system that employs low vibration tracks.
A unique delivery system was set up to transport the rails from an assembly yard in Brooklyn to the Line project site on the West Side of Manhattan. 2013 – December: Mayor Michael Bloomberg rides the first train from Times Square to the new station at 34th Street & 11th Avenue. 2013 – May: Tunneling contract awarded 2013 Construction Project of the Year by NYS Society of Professional Engineers. 2012 – November: Tunneling contract receives an Award of Merit at ENR Best Projects 2012 Awards. 2012 – May: At 65% complete, the extension receives the installation of first set of rails.
2010 – July: Second Tunnel Boring Machine breaks through at Port Authority Bus Terminal – TBM tunneling is complete. 2009 – December: First Tunnel Boring Machine breaks through into 34th Street Station cavern. 2009 – June: Excavation of cavern within the basement of the Port Authority Bus Terminal is complete.
2009 – February: First tunnel boring machine (TBM) is lowered into the shaft on the corner of 26th Street and 11th Avenue. 2007 – December: Ceremony is held in Times Square marking the launch of the subway extension project.
2005 – January: New York City Council approves rezoning to allow for redevelopment and extension for the line.
2004 – June: NYC Department of City Planning certifies Hudson Yards Redevelopment plan, including extension of the subway line.
2003: Proposal made for rezoning of Midtown Manhattan’s Far West Side for Hudson Yards Redevelopment, including extension of the subway line. The line's state-of-the-art station on 11th Avenue will not only be a new hub for the NYC subway system, it will also feature New York’s very first inclined elevator. Aside from being a much needed passage from East to West, the 11th Avenue station is already an architectural step into the future.


The first of its kind in NY, the incline will have an entrance in a new park area on 10th Avenue a block away, and transport commuters sideways down a slope underneath 11th Avenue and into the station. An ADA elevator located in the new park outside of the main entrance provides access to the upper mezzanine. Notably, the station houses the longest column-free platform and the longest escalators inside any station. The station is adorned with 24 55” digital screens on the lower mezzanine that will show advertising and service notices from New York City Transit.
Countdown clocks will come to the station upon completion of the installation of Communications-Based Train Control (CBTC) slated for 2017.
The TBMs were disassembled, pulled through the station cavern, reassembled at its north end, and each relaunched on a path that eventually took it under the Port Authority Bus Terminal. The ground freezing design provided a 325 foot zone of frozen earth that the TBMs could bore through as if it were rock. It is believed this was the first time in the world TBMs both mined and placed precast concrete tunnel liners in a ‘ground freeze’ area. Underpinning is a process where the existing foundations of a structure are adjusted, sometimes being strengthened and sometimes involving the shifting of loads from existing structures to temporary or new ones. These specialized tracks will provide a smoother, quieter and more comfortable ride for customers, decrease the need for track maintenance, and contribute to environmental sustainability by eliminating the use of wooden track blocks. Along with a gorgeous blue skylight, the station will boast other innovative design details and be a retail and transportation center on the West Side for about 35,000 commuters daily. From the upper mezzanine, customers can access the lower mezzanine using five high-rise escalators and the two inclined elevators.
Two inclined elevators between the upper and lower mezzanines travel at a speed of 100 feet per minute and can accomodate five wheelchairs or 15 standing customers to comply with ADA requirements. This allowed the TBMs to traverse the area as planned, maintaining their proper course as well as supporting the tunnels. Read on to see a full video of the strides being made on this exciting new line's construction.
