#7 Subway West Side Extension Hudson Yards Javits Center

This is as of 7/15/10, but I don't think it's been posted here before.

The second of two 1,000 ton tunnel boring machines has reached the chamber adjacent to the current terminus for the No. 7 train underneath 42nd Street. This marks a major milestone in the $2.1 billion project that will extend the No. 7 line to 34th Street and will support the growth of an emerging community on the West Side. The project is funded by the City of New York and managed by the MTA.

The tunnel boring machine (TBM) broke through into 200 ft. x 50 ft. x 40 ft. deep receiving chamber just below the Port Authority Bus Terminal in close proximity to the bus terminal foundation and utilities, as well as the 8th Avenue Subway Line. This is where the new tunnels will connect with the existing No. 7 Line terminus at Times Square.

"This marks the final leg of the second of two, 1,000-ton tunnel boring machines that have mined more than a combined 9,300 feet to reach this point," MTA Chairman and CEO Jay H. Walder said. "It's a major milestone working toward the completion of a project that will increase capacity within our transit system and help redevelop a vital part of our city that will spur future growth."

Thanks for sharing. But I still think the MTA needs to build the station at 10th Avenue for this project to be really useful. With only a Javits stop, it will only be useful on convention days. Even better would be extending the line to 23rd Street to serve Chelsea Piers. That shouldn't be too difficult, given that the tail tracks are supposed to extend to 25th Street.

Another update, although not all that recent: http://mta.info/news/stories/?story=220

Construction of the No. 7 Subway Extension, which will provide new subway service to 34th Street and 11th Avenue, continues to make significant progress. As part of the project's largest contract, boring for two parallel subway tunnels is complete. The contract, which also includes excavation of a three-block long cavern for the subway station, a station platform and mezzanine level, is 85 percent complete. It has a contractual completion date of September 2012.

The concrete pours which create the main cavern arches for the station have been completed.

A systems contract, which will include rail track, all mechanical, electrical and related systems throughout the tunnels, station, ventilation buildings and the main subway entrance at 34th Street is currently in procurement, with a forecasted award date of July 2011. This is the last contract needed to initiate service on the No. 7 Line Extension in December 2013. An additional contract for a secondary entrance to the subway station will be awarded in the future, but its completion is not necessary for service to begin on the new subway extension.

The No. 7 Line extension will go from the intersection of West 41st Street and Eighth Avenue, west under 41st Street, and turn south under 11th Avenue. A new terminal station will be located at 34th Street and 11th Avenue, allowing convenient access to the adjacent development and the Jacob Javits Convention Center.

The 7 line extension will introduce subway service to an emerging mixed-use community in Midtown West, fostering transit oriented development in one of Manhattan's most underserved and underdeveloped areas. The City created two local development corporations, the Hudson Yards Infrastructure Corporation (HYIC), which is contributing $2.1 billion to the project, and the Hudson Yards Development Corporation (HYDC), which oversees planning and development in the Hudson Yards on behalf of the City.

It would be a mistake not to build that station... IMO...

Have to chuckle at the title of the article: Work to begin on NYCT's 7 Subway Line extension

The $513.7 million contract, which was signed in August, was awarded to a joint venture between Skanska USA and RailWorks Corp. The Hudson Yards Development Corp. is providing funding for the contract, MTA officials said in a prepared statement.

The project calls for laying track in newly completed tunnels and installing signals, elevators and escalators, and electrical, lighting, plumbing, heating, ventilating and air conditioning systems.

The $2.1 billion extension, which includes a new station at 34th Street and Eleventh Avenue, is expected to open for revenue service in December 2013.

Obviously, the title does not reflect that it's the FINAL major contract. It just made me chuckle.

<BUMP>

Merged some old topics in and stickied.

So, from what I have read, the tunneling is done. The stations and trackwork need to be built now, correct?

I haven't seen a thing, but I think that's a safe assumption. I'll check the MTA site tomorrow, but it's not always updated promptly....

Correct

MTA official site; I have to say, not updating the construction page since 2009 should be very embarassing to the MTA.

Construction Update — October 2009

A small blurb from the article listed above:

Because of existing infrastructure — like the Lincoln Tunnel and old railroad lines — those tunnels had to be dug extra deep and are steeply curved in spots.

Old railroad lines? What are they talking about, Beech Pneumatic? The original IRT? The abandoned E platform? On the last point, I think not:

The westward expansion also cuts through the famous abandoned E-train platform at 42nd Street, which was featured in the movie “Ghost.”

I would guess the North River and Empire tunnels; agreed that that's a strange wording.

Abandoned E line station?? What's that about?

Thanks. Was unaware of that.
