An ironworker walks past officials as they watch the ceremonial last beam being hoisted to the top of Four World Trade Center, Monday, June 25, 2012. From left to right are: New York State Assembly Speaker Sheldon Silver, developer Larry Silverstein, and Congressman Peter King (R - N.Y.). The 72-floor, 977-foot tower is scheduled to open late next year. It's expected to be the first tower completed on the 16-acre site since the 9/11 attacks. (AP Photo/Mark Lennihan) less
