NEW YORK (AP/CBS2) - The crowning spire of the World Trade Center's tallest building is making its way to New York City.
A barge headed across New York Harbor from New Jersey's Port Newark on Tuesday. It held nine pieces of the steel spire that will top One World Trade Center in lower Manhattan.
Meanwhile, workers on the 104-story skyscraper were busy pouring concrete that will hold the 408-foot spire.
The trade center's director of construction, Steven Plate, says the spire marks a post 9/11 milestone that signifies New York City is "better than ever."
The spire is divided into 18 sections, weighing between 5 tons and
more than 67 tons. Workers will begin hoisting them on Wednesday.
Construction at the World Trade Center site had been halted after Superstorm Sandy left it and the National September 11 Memorial and Museum severely flooded.
Crews completed a massive pumping operation last month.
The Port Authority said it will take about three months to complete the installation of the spire.
Plate says the 1,776-foot high-rise - symbolizing America's freedom - will be the tallest building in the Western Hemisphere.
