The final pieces of the spire that will top One World Trade Center — and make it soar to a symbolic 1,776 feet when fully installed — are scheduled to be raised up to the building's roof.
The Port Authority of New York and New Jersey says the pieces are scheduled to be lifted to a temporary work platform on Thursday morning. They will be installed at a later date.
The 408-foot spire will serve as a world-class broadcast antenna.
