NYC Sky High II
The symbolic cornerstone of One World Trade Center was laid down in a ceremony on July 4, 2004,but further construction of the tower was stalled until 2006. The cornerstone was temporarily removed from the site on June 23, 2006. The project was delayed due to disputes over money, security and design but the last major issues were resolved on April 26, 2006 with a deal between developer Larry Silverstein and the Port Authority of New York and New Jersey. During the summer of 2006, explosives were detonated at the World Trade Center construction site, testing the use of charges to clear bedrock for the building’s foundation. Controlled explosions continued for approximately two months thereafter.
On May 10, 2013, the last two sections of the building’s spire were installed making it the tallest building in the Western Hemisphere, and the 3rd tallest building in the world. The building opened November 3, 2014, to 175 employees of publisher Condé Nast, and opened to the public on May 28, 2015.
