Port Authority terror proofing Tunnels

[3rdrail]

Remember the 1993 bomb plot that targeted the WTC, also targeted the Holland and Lincoln Tunnels, GW Bridge and PATH tunnels. The PANYNJ was the clear target.

The 2001 attack was supposed to have flooded PATH, MTA, and most of lower Manhattan. The slurry walls held and foiled that idea.

The crane is still doing its thing. I think theymay be layering the pads, with one partly over top the other directly over the tube. It seems they are doing the newark bound side first also, based on where the crane barge is located.

It seems the floating crane has moved to the uptown tubes. This should take less time as the tubes are parallel bank to bank. Anyone have any information about the composition/makeup of the blankets they are using?

Do you really think that that kind of specific defensive information should be bandied about on a public forum ?

Second what 3rdrail said. Why would you want to know?

[HBLR]

As i understand it, this is for protection against currents excavating the tunnels from the river sediment, and anchors etc. Why do i want to know? Hm maybe because i'm a human & have curiosity, the same reason for my interest in trains and rail operations, and life in general?

I'll feel way safer when the project is complete!

Good answer ! Here's a tip: Gain a little curiosity regarding this life phenomenon - C o m m o n S e n s e.

Excuse me.. I wasn't aware that guarding against sediment shifts was such top secret sensitive information.

So, i rode around the WTC loop from exchange place yesterday because i didn't feel like waiting to board. The south tube has a lot of that steel plating from the bench wall to about half way to the top, i'd say a good 1/3 to 1/2 of the tunnel has the lining. On the NJ bound side much less of the plating is in place, but it's still probably a good few hundred feet. I am guessing they are working weekends due to the hoboken-wtc trains not running. It looks like pretty serious stuff. I wonder when they will be finished. I am going to try and ride the uptown tubes and see what's going on there when i get the chance.

So I took another look this am. Got to see them do a reverse move from nj while I was waiting at wtc. It looks like they are making rapid progress, still no chance to ride the uptown tubes.
