196 meters! Sichuan Jinyang River Bridge opens to traffic
- Bridge builders continue to overcome problems such as structural design of continuous rigid-frame bridges with ultra-high piers
On June 30, 2022, after nearly five years of hard work, the Lianxin Bridge of the Three Gorges of Jinyang River in Jinyang County, Liangshan Prefecture, Sichuan was officially opened to traffic. The Jinyang River Bridge spans the deep incised valley of the Jinyang River and is constructed by SCBG, a subsidiary of Shudao Group.

The pier is the highest in the world in the same type of concrete-filled steel tubular lattice hollow pier bridge.
Black technology blessing
The bridge has a high technological content, successfully applied for a number of new utility patents, and won the "Second Prize of Science and Technology Progress of China Highway Construction Industry Association" and "Green Transportation Smart Innovation Award of China Communications Enterprise Management Association", and obtained national patents. 15 items. Among the many black technologies, the most hard-core is the self-climbing multi-function lifting system.
