From Dec. 2010 to Jan 2011 the Devon Tower grew from 22 floors to 26 floors. This includes the current floor under construction on the top. The data center on the west side is now taller than the adjacent 10 floor parking garage. For this reason I have added a position for taking pictures. It is now possible to see all of the construction progress from Hudson. Therefore, the first picture below is from that position. I plan to make later shots from that spot.
You can see the progress of the data center on the left hand side of the picture below. I would put the current height of the tower at 450 feet. It is now taller than the Oklahoma Tower.
