More than five years after the destruction of the twin towers, the first steel columns for the Freedom tower will be raised Tuesday morning at Ground Zero.
The 30-ton steel beams are massive, each up to 35 feet long. Eleven more will be delivered to the site by the end of the month.
Construction workers have poured 3,000 cubic yards of concrete to prepare the foundation for the soaring 1776- foot freedom tower, the symbolic cornerstone of New York’s efforts to rebuild after the terror attacks.
