Work continues on One World Trade Center as the building reached 100 stories and approached the height of the Empire State Building.

One World Trade Center is well on its way to a planned 1,776 feet tall, reaching 100 stories this week. We were given the opportunity to spend some time on the site and Rock Center interviewed several construction workers who work there everyday. While many of us feel a sense of pride watching the massive structure grow on a daily basis, these workers are changing the skyline of New York and honoring those lost with every piece of steel.

Six years since construction began on 1 World Trade Center, the tower will soon surpass the height of the Empire State Building's roof. The iron workers placing and setting each beam in the shadow of the 9/11 attacks say they are building out of a "sense of necessity" and know that the tower, now soaring nearly 1300 feet, will help the nation and the iron workers themselves heal. Many of the workers building the tower helped clean the smoldering debris in the days after the terrorist attack. Harry Smith reports.
