New 7 Line Extension to 11 Avenue

Welcome to the 34 St-Hudson Yards Subway Station

7 subway FACTS


The project extends the existing No.7 Line subway service via a 1.5 mile extension from Times Square to the new 34 Street – Hudson Yards station located at West 34th Street and 11th Avenue, with additional train storage tracks south to West 25th Street. This is the only station south of 59 Street to provide service west of 9th Avenue.
The station is designed to handle 25,000 people in a peak hour and is anticipated to become the busiest single line station in the New York City Transit Subway system once Hudson Yards is fully developed.
Budget: $2.42 billion

- $2.1 billion allocated for subway related work
- $266 million allocated for other infrastructure
- $53 million contributed by MTA local funds for environmental studies and preliminary engineering design

Funding was provided by the City of New York via the Hudson Yards Infrastructure Corporation and Hudson Yards Development Corporation.

Owner: MTA New York City Transit
Design and Construction Manager: MTA Capital Construction


The new 34 St- Hudson Yards station will be New York City Transit’s 469th subway station.

  • Primary station entrance: West 34th Street and Hudson Blvd East.
  • Secondary station entrance: West 35th Street and Hudson Blvd East–this entrance is currently under construction.

The underground station extends approximately 1,200 ft. along 11th Avenue from West 32nd Street to West 37th Street.
The station features high-end finishes such as stainless steel tile wall panels, painted steel ceiling panels, granite floor tile and energy efficient lighting. It is air-tempered, maintaining a year-round temperature on the lower mezzanine and platform levels between 72 and 78 degrees Fahrenheit.

There are three public floors in the station: the upper mezzanine (27.6 ft. below street level), the lower mezzanine (109 ft. below street level) and the platform level (125 ft. 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. An ADA elevator located in the new park outside of the main entrance provides access to the fare array area in the upper mezzanine.

Upper Mezzanine Highlights:

  • An oval shaped, stainless steel and glass Station Service Center (formerly referred to as a token booth)
  • A Retail Concession area located behind the Station Service Center.
  • 4 Metrocard vending machines
  • 2 Customer Information Centers with subway and bus maps

Passengers can access the lower mezzanine by 5 high-rise escalators or 2 inclined elevators.

Lower Mezzanine Highlights:

  • Length: 1,025 feet
     Public area: 585 feet long, 50 feet wide

Total On-the-Go Kiosks: 8 (to be installed: 2 at street level/station entrance, 2 in upper mezzanine, 4 on platform)
Total MTA Help Points: 10 (4 on upper mezzanine, 3 on lower mezzanine, 3 on platform)

The station has the largest tunnel ventilation fans in the subway system.


The station has the highest and longest escalators of any subway station in New York City Transit.

Total Escalators: 9 (16 when Secondary entrance is complete)
Total Elevators: 4 (2 vertical, 2 inclined)

Inclined Elevators:

  • 2 inclined elevators located on the upper mezzanine are the first of their kind for the MTA.

  • Length of cab travel: 172 feet
  • Elevator weight capacity: 5000 lbs. per cab
  • Occupancy: Approximately 15 standing or 3-5 wheelchair passengers
  • Speed: 100 feet per minute (approximately 2 minutes from door close to door open)

  • Installer: Kone Inc., Coal Valley Illinois
  • Cost: $2.7M (includes fabrication and installation)


Station features 2 mosaic artwork installations, one over the low-rise escalators and one ceiling dome at the center of the upper mezzanine area.

The artwork, “Funktional Vibrations” (2014) by Xenobia Bailey, was commissioned by MTA Arts & Design following an international competition.


Two Tunnel Boring Machines (TBMs) manufactured in Germany by Herrenknecht were used to mine the tunnels.

  • Length of each assembled TBM: 150 feet.
  • Commenced mining: May 2009
  • Completed mining: June 2010
  • Disassembled and removed from site: August 2010

For the first time in the world a tunnel boring machine drilled through a "ground freeze" area while simultaneously placing precast tunnel liners. This was under 11th Avenue between West 26th and West 28th Streets.

  • Length of each tunnel: 4,700 feet
  • Outside diameter: 22.5 feet
  • Finished interior diameter: 19.5 feet

Controlled "drill-and-blast" methods were used to excavate the underground facilities.
Total excavation resulted in over 409,000 cubic yards of rock, hauled away for various uses via 26,900 truck trips.

Part of the extension was constructed under the Port Authority Bus Terminal, the world’s busiest bus terminal. A cavern was blasted out under the structure to receive the TBMs as they completed drilling operations. More than 6,500 cubic yards of rock was removed. This was done safely, without disruption to the 250,000 daily bus passengers and without impeding Port Authority Bus operations.

The existing A, C and E subway routes, running north –south under 8th Avenue, also needed to be protected during construction of the No. 7 Line Extension. These lines, above the work area, required extensive underpinning. There were no disruptions in service to those subway lines throughout the entire construction operation.
