After crossing the suspension bridge of the Guanting Lake Highway, the first thing to see is the 107.8-meter pylon, which is magnificent! This bridge is the first to use uncoated weathering steel in the same type of long-span suspension bridge in China. During the whole bridge construction process, it is not necessary to paint “beauty” with paint to prevent the paint from falling into the lake and to protect the water quality of the Guanting Reservoir to the utmost extent.
