Second Avenue Subway Discussion

bowery sits in the general area of the chrystie cut, about 2 blocks north of Grand St with its entrance between Chrystie and Bowery. one quick block west the Nassau line begins to turn south to Centre and just east it prepares to have the Chrystie cut tunnels merge with it. Wheres the room to connect? and you cant cay just south of the turn because you have the IRT tunnels very close to it.

Start the connection north of Bowery, I guess and use the north platform for the (T)

 

 

Hold on, we are crossing the (J)(Z), and then onto the (F)? That would be aright, but;

 

1) We would need a new connection between the (J)(Z) and the (F)

2) Essex St is a 3T, Bowery is a 4T. The (T) and the (J)(Z) could use the false wall as a Station at Bowery, but once we get to Essex, all those tracks are taken.

Impossible. I explained that the study showed the soil is not strong enough to connect the (T) to the Nassau Street Line and the Montague Street Tunnel. The (MTA) did a whole study on this and this proved impossible. Unless if you have some alien technology that humans don't know then it won't happen.

 

You guys have to remember that not all of Manhattan sits on land. Parts of the harbor was filled with trash, or soil to make room for more expansion. An example would be Battery Park City. These areas are not suitable to build tunnels in.

"For the optional connection to the Nassau line, the soft soils south of 4th Street make use of a TBM impossible. In this area, cut-and-cover construction or a drilling machine appropriate for soft soils (known as an Earth Pressure Balance Machine, or EPBM), may be used. In addition, the connection requires a shallow profile to join with the existing Nassau line, which is just below the surface along Kenmare Street. This shallow profile, combined with the need to construct both the Houston Street station and the Nassau line connection with cut-and-cover methods, make use of a soft-soil tunneling approach, such as an EPBM, more difficult.

 

Along the existing Nassau line, cut-and-cover construction is expected between the connection and the south end of the existing Canal Street station because of the need to reconstruct a significant portion of the existing structure. For the platform extensions at Chambers, Fulton, and Broad Streets, it is expected that the majority of the work could be completed from within the existing tunnel structure. However, some cut-and-cover construction may be required pending more detailed investigations during advanced design."

 

 

It's just cheaper and easier to bypass this completely.

See? It's not always the easier, cheaper option to just connect to an existing tunnel.

That area alone has always seen its share of subway construction difficulties, accidents and, unfortunately, deaths. most of which occurred duringthe original subway construction in the early 1900s. although technology has advanced in the last century, so has costs. And as you can see in the pdf that Roadcruiser1 linked ( nice. You beat me to it btw. Lol), it's not just connecting the tunnels, it's also in a way, rebuilding the existing infrastructure. It's why they favor building a new line.

Sometimes there actually is a method to their madness.

Exactly. Why would they want to change the plan altogether? I think that would be something for the far future if it were ever to happen.

 

Because this plan is cheaper. The (MTA) is all about saving money and cost neutrality...

Who said it may be cheaper. Sometime cheaper, isnt the more efficient way.

If Nassau st was denied, why would Rutgers be the better option? Too many existing factors may be in they way. Theres benefits to building a new line compared to using an existing line built almost a century ago. Service to brooklyn from jump isnt enough to warrant them to retract the "Commitment to Build a Full Length SAS" they signed back in 2000.

Exactly. It is all pointless. Why not just accept what they are doing now? We don't want to worry about all these problems with Culver, and plus with the Viaduct being fixed, it would be hell.

 

 

The Viaduct would be fixed way before the Second Avenue Subway comes online -_-.
