China is the midst of several megaprojects that will transform its cities.
Over the next decade, China plans to encourage 250 million people - roughly 29 times New York City's population - to move into the country's growing megacities. To cope with that huge migration, the country has invested tens of billions of dollars in giant infrastructure projects.

This month, China will open its most ambitious megaproject yet: a bridge that connects Hong Kong, Macau, and the mainland's southern city of Zhuhai. Stretching 34 miles long, it's the world's longest cross-sea bridge, according to the AFP.
The bridge features six lanes and four tunnels, one of which is underwater.
China also built four artificial islands to support the structure.
Touted as an "engineering wonder," the bridge is made of 420,000 tons of steel — enough to build 60 Eiffel Towers.
Some sections have slight inclines.
Around 40,000 vehicles are expected to use the bridge daily, including shuttle buses running at 10-minute intervals.
Pedestrians will not be able to walk or ride their bikes along the bridge, which will be designated just for cars.
Officials say the bridge will be up and running for 120 years.
The exact price of the project is unclear, but local outlets report that its construction cost somewhere around $15 billion.
The project has faced some controversy due to its expensive price tag, construction delays, alleged corruption, and worker safety concerns. During construction, two workers died, and 19 more were charged with faking concrete test reports.
Construction lasted seven years. The 2012 photo below shows artificial islands China built for the bridge near Lantau Island in Hong Kong.
China is already home to (now, the second) longest sea bridge, which spans 26.3 miles. Completed in 2011, the $1.5 billion structure links the eastern coastal city of Qingdao to the suburb of Huangdao.
The new bridge is one of two big transportation projects that will open in the region this year. By 2019, China's high-speed rail system is set to grow by 2,180 miles.
