云南保山至腾冲高速公路龙江大桥主跨径1196米,是国内最大跨径的山区钢箱梁悬索桥,桥面距江面286米。由于地处腾(冲)龙(陵)地震板块结合处,大桥按9级烈度抗震设防。该桥2016年4月通车,施工中采用了国内最大跨径的缆索吊机。

Longjiang Bridge for Yunnan Baoshan-Tengchong Expressway in Yunnan Province is a mountainous steel box-girder suspension bridge with the largest span in China. Its main span is 1196m and the bridge deck is 286m from the river surface. Because it is located at the junction of the Tengchong- Longling earthquake plate, the bridge was fortified according to the magnitude of 9 earthquake intensity. The bridge was opened to traffic in April 2016 and the longest span cable crane in China was used in the construction.
