Steel construction has reached the halfway point for 1 World Trade Center, the building that many people still call the Freedom Tower.
After years of stalled development, steel at the building reached the 52nd story on Thursday, more than 600 feet above ground.
The tower is slated to stand at 104 stories, with an antenna reaching hundreds of feet higher, bringing it to a symbolic 1,776 feet -- the tallest in the country.
The building was renamed to better attract corporate tenants. But the Freedom Tower name has stuck for many, and still remains on the Lower Manhattan Development Corporation's website detailing the rebuilding.
The skyscraper is one of several envisioned at a rebuilt site, along with a Sept. 11 memorial, transit hub and performing arts center.
