See a steel “rainbow” bridge flying over the green mountains above the Wujiang River in China's Guizhou. Built by CCCC, the Wujiang Grand Bridge has a main span of 504 meters, ranking first among the world's upper-bearing steel tube concrete arch bridges.
With the last deck girder precisely in place, the main body of the bridge has been completed. After completion, it will further facilitate local transportation, promoting the development of the regional economy and tourism industry.
