A blue "great dragon" lies on the Hongqi Lishui Road. As a national key railway project, Guangzhou Nansha Port Railway is a controlling project. The main bridge of the Hongqi Lishui Road Bridge has a total length of 998 meters and adopts a dual-track railway (138+360 +360+138m) Flexible arch structure with steel truss beams, with a double main span of 2×360 meters, which is difficult to design and construct. After completion, it will become the largest span bridge of its kind in the world.

Always have the ambition to be courageous, and always be grateful. Only with all kinds of changes can we achieve all kinds of attitudes. Our business is evolving, and technology and people must keep up with the speed of evolution.

The Nansha Port Railway can be called the “Long-span Railway Complex Bridge Museum”. The Xijiang cable-stayed bridge with a main span of 600 meters, the Hongqili steel truss flexible arch bridge with a main span of 2x360 meters, and a 175-meter main span of Jiya Waterway Tiehe constructed parallel-chord steel truss girder bridges, Longxue South Cable-stayed Bridge with a main span of 448 meters, and a tied arch bridge of the Xiaolan Waterway with a main span of 230 meters.

ZINDN cold spray zinc assists Hongqili Bridge to reduce maintenance and repair work and improve structural durability. The use of cold spray zinc is equivalent to putting on a protective coat for the steel beam, which does not need to be changed for a long time, saving manpower and financial resources for maintenance.
