Presently under construction, the airport is scheduled for completion in late 2007. According to the U.S. Embassy to China, the country will be building 108 new airports between 2004 and 2009 - including this one, the world's largest. Planned to be open for the Beijing Olympics in 2008, the airport terminal will cover more than 1 million square meters, a larger footprint than the Pentagon.
It's designed to handle 43 million passengers a year initially and 55 million by 2015. That will cause it to be one of the top 10 busiest airports. Because of the scale and traffic, the planners are focussing on making certain that walking distances are short.
