Final sections of 1 WTC spire to be lifted to roof

NEW YORK - 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.

The new tower is at the northwest corner of the World Trade Center site, which is well on its way to reconstruction with the 72-story Four World Trade Center and other buildings.

The raising of the pieces was originally scheduled for Monday, but was postponed because of weather issues.
