Witness One World Trade Center Construction with Time-Lapse Video

Witness history in the making no matter where you are with this time-lapse video of One World Trade Center rising into the New York skyline thanks to your construction estimating company, ProEst!
EarthCam posted the video to YouTube to celebrate the opening of the One World Observatory on the 100th, 101st and 102nd floors, which sits atop the tallest building in the Western Hemisphere at 1,250 feet. The footage covers October 2004 to Memorial Day 2015, using hundreds of thousands of high-definition images.

When entering One World Trade at ground level, visitors watch video interviews from construction crews who built it. They then bolt up to the observatory riding the fastest elevators in the Americas while life-size LED screens show a sped up history lesson of Manhattan's growth from the 1600s to the present. In a theater at the top, visitors watch another video about modern New York and the wall opens up to reveal the spectacular view from the observatory, which features views of New York and up to 50 miles beyond it.

The observatory features three restaurants and on the elevator trip down, LED screens mimic a helicopter ride through the city sky. Standard admission tickets for the One World Observatory are sold online at $32 for adults and $26 for youths. Summer hours are 9 a.m. until midnight.
