The Jiangyin Yangtze River Highway Bridge is the first super-large steel box-girder suspension bridge that spans more than one kilometer in China. It is the longest steel boxgirder suspension bridge in China, the fourth longest in the whole World. It services a superhighway which is the national key trunk
route crossing the Yangtze River. The Jiangyin Yangtze River Highway Bridge is the second suspension bridge that was constructed over the Yangtze River. It lies between Jiangyin and Jingjiang of Jiangsu Province, at the lower reaches of Yangtze River.

| The upgrade and modification of the superstructure health monitoring system of Jiangyin Yangtze River Highway Bridge was completed using the Leica Geosystems' GPS monitoring system that focused on the monitoring of the girder geometric form and the displacement of the bridge towers. The challenge was to provide a cost effective and innovative solution for delivering 3D positioning information at 20 Hz from several GPS Monitoring stations to an advanced analysis application software developed by the engineering company in charge of the whole structural monitoring project. |
