VIDEO: Final WTC spire is lifted
The Port Authority of New York and New Jersey have released footage of the final segment being lifted atop One World Trade Centre on Friday (local time).
The video provides a spectacular view of New York City, looking down from 1776ft.
Installation of the final two sections of the 408-foot, 758-ton spire was completed after pieces of it had been transported to the roof of the building last week. It will serve as a world-class broadcast antenna.
Watch the video for the footage.
