China's new Jiaozhou Bay bridge
The land that brought you the Great Wall has unveiled its latest engineering marvel: a 42.5-kilometre bridge that is built almost entirely over water.
Spanning Jiaozhou Bay in northern China, the three-way bridge connects the port city of Qingdao with the industrial locale of Huangdao and an airport on an adjacent island.
The six-lane, 33.5-metre-wide carriageway was built using 450,000 tonnes of steel and 2.3 million cubic metres of concrete, and reportedly cost more than US$2 billion (NZ$2.4b) to build.
There are 5200 pillars supporting the behemoth bridge, which is said to be strong enough to stay solid through a magnitude eight earthquake and even sturdy enough to stay standing if hit by a 300,000-tonne ship.
