One World Trade Center

摘要

One World Trade Center's 408-ft-tall steel spire, which sits atop the skyscraper's 1,368-ft superstructure, makes the 1,776-ft-tall One WTC the tallest building in the Western Hemisphere and the fourth tallest in the world. The spire was so unwieldy, the steel contractor broke the 758-ton structure into 17 sections for shipping. Each was barged into New York Harbor before crews trucked it to the site in lower Manhattan.
