The entirety of the World Trade Center Oculus is less than a year away from completion, but over the last month, new pieces of architect Santiago Calatrava's "bird in flight" have opened, giving the public a fresh look at the gleaming transportation hub. The Daily News has photos from a construction tour this week that shows the latest updates and the recently opened Platform B. The platform's mezzanine level, shown above, is kind of amazing and shows off the station's soaring ribbed structure. This $4 billion structure may be wildly over budget and super delayed, but at least it's going to be pretty mind-blowing when it's finished.

The WTC Progress Facebook page shared photos this week of escalators being installed (↑)...
