1 WTC to be tallest building in western hemisphere

New York, April 28 (IANS) Construction crews at the 9/11 site will raise the final two sections of a 408-foot spire to the top of the One World Trade Center building Monday, making the building the tallest in the western hemisphere.

A stainless steel beacon weighing almost six tonnes will be the final piece put in place to give the building an iconic height of 1,776 feet, CNN cited a statement from the Port Authority of New York and New Jersey as saying.

Once the architectural structure is complete, it will comprise of 18 separate sections of steel and three communication rings.

The first - and heaviest - steel section was installed in January, weighing more than 67 tonnes.

The spire will serve a TV broadcast facility housed in One World Trade Center.
