A year ago, I snapped this picture of the big hole that was Ground Zero five years after 9/11.
See the progress, after the jump.
Gothamist predicts that the Freedom Tower will open in 2011 whether it's finished or not, to coincide with the ten-year anniversary of 9/11. When completed, the $16 billion World Trade Center rebuilding project will be the most expensive ever for New York City.
If you'd like to follow the rebuilding in real time, bookmark this live webcam at Ground Zero. There may be outages today, as more than usual traffic is expected for the anniversary of 9/11. There are more anniversary links today at Ursi's Blog.
