Weather delays 1 WTC's crowning

Rain has set back 1 World Trade Center’s new plateau.

Construction crews were planning to raise the last piece of the 104-floor skyscraper to its roof Monday, but high winds forced officials to postpone the lift until the weather cooperates.

When the spire is eventually installed, 1 World Trade Center will be the tallest building in the Western Hemisphere at 1,776 feet, according to the Port Authority of New York and New Jersey.

The final piece, at nearly six tons, is just one of 18 sections weighing 800 tons.

Crews lifted the first section of the 408-foot spire to the roof in December.
