One World Trade Center Nearing Final Height

Crews installed the first piece of the new building's 408-foot spire on Jan. 15. When the spire is completed in two to three months, the building will be 1,776 feet tall.

Construction of the Port Authority of New York and New Jersey's One World Trade Center soon will reach its final height, 1,776 feet. The authority announced Jan. 15 that workers installed the first section that morning of the 408-foot spire that tops the structure. The spire consists of 18 sections and three communication rings, with a stainless steel beacon being placed at its top; the spire serves as a broadcast facility.

The authority's news release said ironworkers and crane operators used two cranes to lift and guide the first section of steel spire, which weighs more than 67 tons, into a 6-foot concrete base on the building's roof. This first section and eight other large sections arrived by barge from Valleyfield, Quebec in November 2012, and the other nine sections were brought in on trucks.

One World Trade Center is the city's tallest skyscraper. The authority owns and manages the 16-acre World Trade Center site.
