The silver spire topping One World Trade Center on Friday was fully installed on the building’s roof, bringing the structure to its full, symbolic height of 1,776 feet.

Loud applause and cries of joy erupted from assembled construction workers as the spire was gently lowered and secured into place.

“It’s a pretty awesome feeling,” said project manager Juan Estevez from a temporary platform on the roof of the tower where he and other workers watched the milestone.

“It’s a culmination of a tremendous amount of team work … rebuilding the New York City skyline once again.”
