The pedestrian bridge at an intersection of the Gu- angzhou-Yunfu highway in the town of Dali has an oval sh- aped steel truss main structure. The long axis of center line of the bridge is of 95.3 m, and its short axis is of 79.2 M. This paper introduces the design of the upper structure of the bridge, carries out the static, dynamic analysis of the bridge, discussi- ng the closed bearing arrangement method of elipse truss br- idge.
