One World Trade Center (formerly known as Freedom Tower) reached a milestone shortly after 2 PM today. It became the tallest building in New York City, surpassing the Empire State Building which had been the tallest skyscraper since September 11, 2001. During today’s milestone, two, 26-foot steel interior columns were attached to the top of 1 WTC, reaching a height of 1,271 feet above street level, according to the Port Authority. In the coming months, 1 World Trade Center will top out at 1,368 feet, (104 stories) and then get a 408-foot telecommunications spire that will push the tower’s height to 1,776 feet. It will be the tallest building in the Western Hemisphere. The building aims to open in 2014. The images above were made earlier this evening.
