One World Trade Center Spire: Workers Begin To Hoist Spire Atop City's Tallest Building (PHOTOS) (VIDEO)

Workers lifted the first section of the 408-foot spire to the top of One World Trade Center Wednesday morning. When completed, the spire will bring One WTC to a staggering 1,776 feet tall, making it the tallest building in the Western Hemisphere.

Since November 16, nine of the sections have been traveling 1,500 nautical miles to Lower Manhattan via a barge from Canada.

The rest of the sections will arrive by truck later this month.
