Amazing!
Now, what will they do about the subway? (I'm not familiar with NYC, could they back up and run the line up higher, or what? Are there laws in place to protect archaeological discoveries?
Well, down in the financial district (Old Niew Amsterdam) they can't do anything above ground. They will have to tunnel through the wall as it lays (hopefully they will bring that section above ground and place it in Battery Park so we all can see it).
