UPDATE: The Port Authority of New York and New Jersey has postponed the raising of the last pieces of the World Trade Center spire due to high wind conditions today.
Metro’s original story is below.
Construction crews are scheduled to raise the last pieces of One World Trade Center’s spire this morning, making it just feet from becoming the tallest tower in the Western Hemisphere.
The 408-foot spire and a steel beacon that will be added at a later date will complete the tower at 1,776 feet.
The spire will serve as a world-class broadcast antenna, the Associated Press reports.
The 104-story tower is expected to open for business in 2014.
Completion of the spire comes just days after police discovered a piece of landing gear, believed to be from one of the planes that crashed into the twin towers, behind the Park 51 Islamic cultural center.
