Hah, yeah they have "evacuation procedures" for the people in the tunnel if anything happened. I think you'd be done for. And if it was between losing a single train and having half of the subway system under water along with the bottom levels of the WTC... well, what would you choose?
That being said, it's good that they are reinforcing the tunnels and adding gates.
Don't some rail tunnels have parallel service corridors, and in the case of under water situations... with sealable bulkheads that could provide spaces for safe refuge? But yeah if not, that would be a pretty bad scenario.
The MTA is nearing completion on a $250 million anti-terror project to reinforce underwater subway tunnels and bridges against a bomb blast, The Post has learned.
Since 2004, agency contractors have been lining subway tubes -- especially the 10 that run under the East River -- with high-impact-bearing metal that would prevent collapse or massive flooding in the case of a terrorist attack, multiple sources said.
And in the more shallow tunnels that aren't fully dug into rock, like the F line that connects 63rd Street to Roosevelt Island, workers dropped massive slabs of rock and concrete on the riverbed to prevent disaster, the sources said.
The Post revealed yesterday how the Port Authority is paying $600 million to beef up the vulnerable PATH subway tunnels beneath the Hudson River with blast plates and floodgates that would withstand rushing water in the case of an explosion.
But the MTA's security makeover isn't limited to tunnels. The agency's seven bridges are being "hardened" with plates and "collars" on cables that can resist a blast, sources said.
The agency originally planned to use a lightweight, blast-resistant material to ring the tunnels -- but sources said that various types of materials have been used.
One of more complicated tasks was determining which parts of the aged tunnels were bored deep into rock and which parts come close to the surface.
"That presents several issues. With some tunnels, there's a point where they come out to the surface and there's different vulnerability there than with tunnels in bedrock," one source said.
In January, the state comptroller reported that "93 percent of all facility hardening was completed" and that the MTA's project cost about $22 million more than expected.
"A lot has been done in regards to hardening, and that work continues to move forward," said agency spokesman Kevin Ortiz.
The longest tunnel under the East River is the N, R, and W line's 5,500-foot tube that connects 60th St. in Manhattan to Queens.

hehehe. look at this statement posted on the live camera section of the 9/11 memorial & museum website: The webcam is exposed to inclement weather, the online video feed may be temporarily disrupted. We apologize for any convenience this may cause and will address any technical problems in a timely matter. Isn't the pink/bold/italic/underlined part funny? I think they meant "We apologize for any INconvenience this may cause".

It appears the former Twin Tower tridents have been exposed on the Live Camera. The Pavilion is nearly complete. Now the only thing that is left is to apply fire-proofing and the building's curtain wall (cladding).
Wow. It's really lit up.

The Chunnel, built in the 1980's does. Path tunnels built in the 1880's? Not so much.
There are 4 super columns that will eventually support the #1 subway box, among other things. They will go on those big concrete piers.
But after taking another look at it in the sunlight it's not in fact a super, it's a section of box girder. But it's about twice as long as the sections already up.

I really don't understand the construction for this thing. Are they going to take down that construction road or just build all over it as is? I mean, They're pouring concrete right through the support beams all over the place. Is that permanent? Then they keep removing and relayering the road with plywood over and over again. I thought at some point this thing would be torn down. It's making no sense whatsoever how this is all going to turn out in the end.

You thought what would be torn down?

That's not a temporary construction access road, that's the #1 subway box, and it is open with trains running through it. They happen to be using it for construction access.
Wow thanks zen, so the subway box is being elevated and there will be the basement/shopping malls underneath. Interesting indeed.
My understanding is that the tracks where at bedrock level in the old WTC, right?
