Pingtang Bridge in southwest China's Guizhou Province, boasting the highest concrete bridge tower in the world, makes the once landlocked province leap at the chance of transportation development.

Located in Bouyei-Miao Autonomous Prefecture of Qiannan, the bridge, a colossal cable-supported viaduct with a span of 2,135 meters, will serve as a major connection on the Pingtang-Luodian Expressway above the Caodu River Canyon.

With a height of 332 meters, the diamond-shaped main tower features the world's tallest reinforced concrete bridge tower.

The bridge will be completed and open to traffic by the end of 2019, which is expected to cut the travel time between the canyon by at least an hour.
