Jiaolongba Bridge in Tibet is a controlling bridge connecting Markam County in Tibet and Dêqên County in Yunnan Province on the 214 National Highway (Yunnan Tibet Highway). It is the only way for the southern line to enter Tibet, and its strategic position is very important. The main span of the Suspension bridge is 345 meters, which effectively avoids the impact of adverse geology such as debris flow. The foundation of the cable tower and the anchors on both banks make full use of the bedrock. The main girder of the truss is divided into manufacturing sections and installation sections, giving consideration to the construction conditions and the force of the completed bridge
