A: Believe it or not the 2nd Avenue Subway project is alive and well as we near the beginning of tunnel construction below 96th Street on 2nd Avenue. Although I missed the community meeting on Monday, PeakGuy did go and found out that construction is set to start in 40 Months!!

Tunnels are expected to begin construction in 3 1/2 years from 92nd Street to 62nd Street with new stations at 96th, 86th, 72nd, and expansion of a existing Lexington Avenue/63rd Street station. Also set begin construction are track and systems from 105th Street to aproximately 62nd Street. Download the .pdf from MTA site.

Here is a conceptual drawing of Phase 1:

In case you missed the Discovery Channel on how Tunnels are built, they will be using a boring machine that looks something like this and will use the streets as entry points 1 section at a time....

According to Wikipedia: Tunnel boring machines are used as an alternative to drilling and blasting (D&B) methods. A TBM has the advantages of not disturbing surrounding soil and producing a smooth tunnel wall. This significantly reduces the cost of lining the tunnel, and makes them suitable to use in built-up areas. The key disadvantage is cost. TBMs are expensive to construct, difficult to transport and require significant infrastructure.

What To Expect During Build: Streets to be completely demolished during the boring process and tunnel build. Local businesses on 2nd Avenue will have a rough time and will most likely go out of business temporarily with some type of city support program kicking into effect. A few years of loud noises, construction barriers, air pollution, and big time machines.

What To Expect Upon Subway Completion: A spike in real estate values for properties surrounding this brand new, technologically superior subway line to ease congestion on NYC's eastside. Buying a property that is discounted because it is too far East right now is probably a very wise idea when the subway construction begins; York Avenue & East End Avenue are my sleeper picks for 8-10 years down the road when subway is complete.

Thanks to Glenn over at The Oil Drum:NYC, a great blog covering the energy markets, for going to the 2nd Avenue Subway community meeting Monday night and providing me with this latest information:

* They are going to have to reclaim some street space at the 96th Street station entrances to make it fit. Entrances on 93rd (east and west sides) and then another on the West side of 96th street. Either they are taking out parking or they might have to take out a lane of traffic. I'm guessing the parking...

* Because the 96th Street station is close to the surface (Cut and Cover technique) there is going to be massive construction for the 96th street station in the middle of the street for many months. This will create traffic chaos unless they do something to reduce the number of cars coming into Manhattan. Perhaps they could divert it to the FDR or York. Lexington Ave is already a disaster area.

* The 72nd Street station will be very deep and will not require the cut and cover technique. Entrances on 69th and 72nd. One of them will occupy where Patsy's Pizza is now. They are going to have to tear down a building on the NE corner of 72nd street for ventillation.

* There will be a meeting in May to discuss the 86th street station.

* Bids are going out in December and construction should begin in 2009 and last for 2-3 years. I think they said the first phase (96th to 63rd) will be done in 2012-13.
