Lyuzhi River Bridge, the first single-tower and single-span steel box girder suspension bridge in the history of highway construction, was recently granted the "Best Construction Innovation Nominee Award" by the International Association for Bridge and Structural Engineering (IABSE).
The awards ceremony was held in Zurich, Switzerland on Nov 8.
Since 2000, the IABSE has established its "Outstanding Structure Award" to honor the most innovative bridges and building structures worldwide.
This year, the association has divided the awards into seven categories, with the Construction Innovation Award being presented to entities that achieve outstanding project results through the use of innovative building materials, products, methods, or equipment.
Lyuzhi River Bridge lies on the Yuxi-Chuxiong Highway in Southwest China's Yunnan province.
It was designed by Guizhou Transportation Planning Survey and Design Academe Co, an enterprise in the Guiyang National High-tech Industrial Development Zone (Guiyang HIDZ) in the city of Guiyang in Guizhou province.
The bridge, nestled in the pristine natural landscape of the Lyuzhi River Grand Canyon, has achieved the harmonious unity of human engineering and the surrounding environment.
This design has set three world records as a single-pylon suspension bridge with a maximum span of 780 meters, a maximum inclination angle of 54 degrees for tunnel anchors, and a maximum height of 320 meters for stiffening beam hoisting.
Thanks to its groundbreaking zero-excavation construction technique for steep slopes and comprehensive anti-rockfall technology, Lyuzhi River Bridge successfully completed its engineering work on the canyon's sheer cliffs.
This feat not only protected the area's natural topography but also helped to preserve the diverse wildlife and plant resources found within the canyon.
The winning of the award marks yet more international recognition for the Lyuzhi River Bridge, after it previously pocketed the 2023 FIDIC Global Infrastructure Excellence Project Award.
The bridges designed by Guizhou Transportation Planning Survey and Design Academe Co have won nine major international awards.
