Due for completion in 2016, the stunning Lancanjiang Railway Bridge is the centerpiece of a new line between the cities of Baoshan and Dali in western Yunnan Province. The new railway bridge crosses the upper reaches of a reservoir that was formed behind Xiaowan, the 2nd highest concrete dam in the world. The spectacular 958 foot (292 mtr) high double curvature structure holds back a body of water some 787 feet (240 meters) deep along the Mekong (Lancang Jiang), a river with several of the largest and highest hydroelectric dams in the world including the Manwan, Dachaoshan, Nuozhadu and Jinghong. The Mekong River is the only international river in Asia linking 6 countries. The river has more species of fish than any other waterway on earth except for the Amazon. The full reservoir is 164 feet (50 meters) deep beneath the new railway bridge.

Instead of using cable stays and tiebacks to build the arch, the two steel truss arch halves were built vertically on either side of the canyon slopes on top of scaffolding. While still in a vertical position, the two halves were then then lowered down over the gorge where they were connected at the crown. A highline was then used to build the vertical spandrel supports and road deck. The total length of the bridge is 698 meters.

The location has become a showcase for 3 high spans including an older suspension bridge, the new railway bridge and an even higher pipeline suspension bridge that is the 3rd highest of its type in the world after the Hegigio Gorge Pipeline Bridge in Papua New Guinea and the Niouc Bridge in Switzerland.
