The News has some recent photos from the top of One World Trade Center, and a few of them are pretty amazing. I went to a planning event on Tuesday at the Museum of the American Indian, which is located in the old U.S. Custom House on Bowling Green (an amazing building, itself). Heading back to the PATH train, my event companion and I walked along Church Street, past the Trade Center site. I was surprised to see the sudden progress that’s now been made on the other buildings. I thought I’d read somewhere that the developers were going to hold off on the second and third main-site towers until the commercial real estate economy recovered. But the tower at the southeast corner of the site, at Church and Liberty Streets, seems to have gone up overnight; while the one at the northeast corner, at Church and Vesey, now has a ground level that’s beginning to take shape. Meanwhile, the frame of One World Trade itself now appears to be approaching its ultimate height. (Seven World Trade Center, across Vesey Street from the main site, was the first to be completed.) After all the maddening time it took to plan and approve the new complex, it’s now being built very quickly.
