The Chinese are building a new airport just outside of Beijing, because the other two giant airports they have in the area just can't keep up with demand. When it's finished, it'll be the largest airport in the world by far, at approximately the same size as the entire island of Bermuda.
Beijing's new airport will be located about 30 miles outside of the city center, although by the time it's completed, the city of Beijing will likely have expanded and absorbed two other nearby cities to form one giant ultramegasupercity. To deal with the growing demand for air travel, the airport will boast eight runways (plus one extra for the military) and enough capacity to handle up to 200 million passengers per year. For the record, this is more runways than any other airport, and more capacity than any other airport, besting London's Heathrow by a factor of two.
At just shy of 21 square miles in size, the new airport will be only about a square mile or two smaller than all of Manhattan. Chinese workers just started breaking ground this year, and the first phase of the new airport (which will only be able to handle a mere 120 million passengers per year — compared to America's busiest, Hartsfield-Jackson Atlanta International Airport, which regularly serves between 80 and 90 million) is scheduled to be operational by 2015.
