Jinshajiang Bridge of Jingkun Expressway

The Jinshajiang Bridge of Jingkun Expressway is a cable-stayed highway bridge spanning approximately 3.5 kilometers across the Jinsha River, featuring multiple piers over 80 meters in height and a main span of 245 meters constructed with prestressed concrete design.

Construction of this bridge was completed to serve the G5 Jingkun Expressway connecting Beijing to Kunming, facilitating the development of highway infrastructure in southwestern China and improving regional connectivity between Sichuan and Yunnan provinces.

The bridge serves local communities in Yanbian County, an area known for diverse ethnic groups, by enhancing mobility and commerce, contributing significantly to the socioeconomic growth and regional development of the Sichuan-Yunnan corridor.

The bridge is part of the G5 Jingkun Expressway and connects Panzhihua to surrounding regions, serving as a critical transportation link for commercial and passenger vehicles traveling through southwestern China's mountainous terrain.

The tallest pier of the structure, Pier No. 25, reaches a height of 115 meters, and the bridge deck's clearance above the Jinsha River can vary by several meters during seasonal flood periods.
