Workers are almost finished installing the last of the glass cladding to 1 WTC. Yesterday, the WTCProgress Twitter tweeted a new photo that revealed the bluish glazing in all its glory. “One WTC’s curtain wall is now 90 percent complete between floors 90 and 100,” the tweet read. Work on the tower’s controversial spire is concurrently being done, according to a message dated March 25, which stated: “As of today 12 pieces of One WTC’s spire are installed weighing 582.9 tons which is approximately 283 cars.” You can see the beginning of the spire nestled just beneath the crane installed at the top of the budding skyscraper — already New York’s tallest structure.
Below is a side-by-side comparison of 1 WTC in its current state and what it will look like once completed (in 2014).
