Beijing Daxing International Airport is a massive complex built on the outskirts of Beijing, China, from more than 220,000 tons of steel, with a price tag nearing 14 billion U.S. dollars, and is set for completion in September 2019. The new facility—billed as the world’s largest single-terminal airport—will be Beijing’s second international airport, and developers hope it will relieve pressure on overtaxed existing travel options. By 2025, planners say Daxing will be able to carry as many as 72 million passengers a year.
