World Records: "Tallest & Longest Span in Mountainous Terrain"
The 2,890-meter-long Huajiang Canyon Bridge, a linchpin of the Liuzhi-Anlong Expressway, features a 1,420-meter main span and soars 625 meters above the river—dethroning the Beipanjiang Bridge (565m) as the world’s tallest. It also sets a new global benchmark for the longest span in mountainous terrain, earning the title: "World No.1 in Both Height and Span."

Defying the Canyon Winds: "Multi-Directional Joints" for Ultimate Resilience
Perched in a wind corridor, the bridge faces complex gusts and vortices, with recorded wind speeds reaching Category 12 typhoon strength. To withstand these forces, all 22 critical expansion joints utilize Lubao Technology’s pioneering anti-warping, multi-directional displacement systems.
The four main RBQF2160 joints (with ±1,080mm displacement capacity) feature: 6D movement (longitudinal, transverse, vertical, rotational, etc.); Self-adaptive anti-warping sliders to keep comb plates flush, preventing debris buildup; Storm-proof durability for extreme weather.
From Chasm to Corridor: Powering Guizhou’s Economy
Once operational, the bridge will slash travel time between Liuzhi and Anlong from 3 hours to just 90 minutes, accelerating regional development and resource flows. Stay tuned for the grand opening!
