re: #405 garhighway

I think you’re short changing the 1WTC/Freedom Tower by a bit. It’s closer to 60 stories right now (and rising at about 30 feet a week). 4WTC, the tower diagonally across from the Freedom Tower is about 20-stories tall. Both of those towers have 3 tower cranes working on them and the Freedom Tower’s 3d tower crane is actually a crawler that runs up the side of the building with the express purpose of delivering concrete to the floors. That’s an engineering marvel in its own right.

I’ve counted at least 18 cranes on the site, with 10 of them being tower cranes, and several of them in the super-lift category (necessary to lift the massive beams for the transit hub and other key components.

It’s amazing to behold - and some of the more amazing scenes are below ground where you can’t see the work to build the transit hub and the other Ground Zero components - all while keeping the PATH system operating on a normal schedule.
