The closure of steel truss arch of Yachihe Bridge on the high-speed railway linking Guiyang and Qianxi in southwest China's Guizhou province has been completed on Saturday.
The Yachihe Bridge, the steel truss girder cable stayed bridge with the main span of 436 meters, is a key section of the Chengdu-Guiyang high-speed rail.
It is said to be the first high-speed rail steel-concrete composite arch bridge in the world, a true engineering feat.
The rail line is expected to open to traffic in 2019, shortening the travel between the two cities from nearly 20 hours to around 2 hours.
