Article Photos: Weather postpones trade center's ascent to tallest 3/3

FILE - In this file photo of April 18, 2013, construction cranes work on assembling the rising spire on top of One World Trade Center in New York. It is already New Yorkâs tallest building. But when the last pieces of its spire go up to the roof Monday, April 28, the 104-floor skyscraper will be one step away from becoming the highest in the Western Hemisphere.
