IMPOSSIBLE BRIDGES – CHINA

Over to China, for one of the greatest bridge-building booms of all time. Three ultimate bridges call China their home: The Lupu is the longest arch bridge in the world; the Runyang is the largest suspension bridge in China (third longest in the world) and the Sutong is soon to be the longest cable-stayed bridge in the world. To build these structures engineers have had to battle floods, unstable soil, strong currents, and potential ship collision.
