China has announced plans to create the world's largest city.
The plan is called "Turn the Pearl River Delta into One." It will merge nine cities, creating an urban area 26 times larger than Greater London, with a living space of 16,000 square miles.
It will take six years to complete and require about 150 major infrastructure projects, including connecting transportation and water systems.
"The idea is that when the cities are integrated, the residents can travel around freely and use the health care and other facilities in the different areas," Ma Xiangming, the project's senior consultant, told the Daily Telegraph.
"It will help spread industry and jobs more evenly across the region and public services will also be distributed more fairly," he added.
Ma said phone bills will drop by 85 percent, rail ticket prices will drop drastically while hospitals, and schools will improve.
The price tag is the equivalent of more than $260 billion. By 2025, it will have added about 350 million people to its population.
