the stiffening girder with the main span of 1,386m, critical for the
construction of Huaping-Lijiang Highway.The Bridge of the tunnel anchor, cable
tower, cable saddle, cable, plate-truss and stiffening girder is the
steel-truss suspension bridge under construction with the largest span in
valleys in the world at present. The main girder is of the plate-truss and
stiffening girder. The Bridge consists of 128 sections, of which the floor plate
is of the U-rib of fusion butt welding, the first in the steel bridge in China.
