(CRI Online) 13:29, November 15, 2016




Photo taken on November 12, 2016 shows the Ganhaizi Bridge, the world's longest concrete tubular bridge. Built to stand 2,500 meters above sea level, the bridge is 1,811 meters long, 24.5 meters wide and has 36 bridge spans. The huge "roller coaster" boasts the world's highest steel pipe concrete lattice pier, composite pier and hybrid bridge pier. It is the first bridge to use steel fiber concrete as structural material. It makes an important part of China's first high speed "double helix tunnel" through the mountainous Yaxi expressway of Ya'an City, southwest China's Sichuan Province. [Photo: Chinanews.com]

Yes, 大瑞铁路.

Is that finished bridge besides Hangzhou-Ruili expressway?

Is that finished bridge besides Hangzhou-Ruili expressway?

Yes, I think so. The bridge is in 大保, 大理－保山 expressway is section of Hangzhou-Ruili.

The Lancang River Railway Bridge is an arch bridge under construction linking the cities of Baoshan and Dali in western Yunnan Province, China. Once completed, the bridge will be one of the highest in world, sitting 271 m (889 ft) above the Lancang River. The bridge's main span will be 342 m (1,122 ft) making it also one of the longest arch bridges ever built. The bridge is expected to be completed in 2018.[1]

Design
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 lowered over the gorge where they were connected at the crown. The total length of the bridge is 698 meters.

Site
The site showcases three high spans including an older suspension bridge, the new railway bridge and an even higher pipeline suspension bridge that is the third-highest of its type in the world after the Hegigio Gorge Pipeline Bridge in Papua New Guinea and the Niouc Bridge in Switzerland.

The official height of the bridge is 271 meters, measured to the river's original surface. The construction of the Xiaowan Dam downstream created a reservoir that extends back under the bridge and raised the water level some 50 meters.
​

That finished bridge is the pipeline suspension bridge highlighted above. It is the China Myanmar pipeline bridge. It carry oil and gas from Myanmar.

Ancient town Tucheng and Tucheng Expressway Bridge
Xishui County, Guizhou Province

Tucheng Bridge crosses the giant Chishuihe River in northern Guizhou Province on the Zunchi expressway that connects Renhuai City to the Guizhou/Sichuan border. The central span configuration is 107+200+107 meters that rest on piers as tall as 109 meters. The two side by side viaducts are 930 and 880 meters long. The bridge is located at kilometer 95.

The 4-lane Zunchi highway has several other large beam bridges including Tongzihe and Eralanghe which have piers that rank among the tallest in the world.

One of longest arch bridges in China successfully closed
2016-11-17 15:52 | People's Daily Online | Editor:Li Yan

A steel-tube arch bridge in Yunnan province was successfully closed on Nov 15, 2016. The bridge, which sits 270 meters above the Lancang River, is part of the Dali–Ruili Railway in Southwest China's Yunnan Province. The main body of the bridge has a span of 342 meters, and the entire length of its bridge floor is 528.1 meters, making it one of the longest arch bridges China has ever built. And it is also the world's first bridge which was constructed using the "secondary vertical turn" construction method. (Photo/Xinhua)
