Beijing is to build a new airport, which is likely to be the world's largest in terms of passenger traffic, to the southeast of the city, China National Radio reports.

The new airport, yet to be named, is to be located on the border between Beijing and Langfang, a city in north China's Hebei province which surrounds Beijing. It will be approximately 45 kilometers from Beijing's city center; about an hour's drive.

The airport is designed to be a key international airport. It will have nine runways and is expected to direct more than 130 million passengers and 5,500,000 tones of cargo annually, replacing the Hartsfield-Jackson Atlanta International Airport in Atlanta, Georgia, the United States, to become the busiest in the world.

The new airport will also act as a hub, connecting highways, transportation roads and roads in rural areas together.

This will be the third civil airport in Beijing, following the Nanyuan Airport and the Beijing International Airport, which houses Terminal three, the largest building in the world.

When put into use, the new airport will serve Beijing, as well as the nearby Tianjin municipality and Hebei province.
