Liuguanghe Bridge, Road bridge in Guizhou, China
The Liuguanghe Bridge is a road bridge crossing the Wu River valley in Guizhou, serving as part of the national highway system connecting inland cities. Its structure uses a box girder design supported by tall concrete piers to span the deep valley below.
The bridge was built to improve road connections between Bijie and Guiyang through challenging mountain terrain in the early 2000s. It gained international recognition for its engineering achievement in a region previously difficult to access by modern highways.
The bridge serves as a symbol of China's engineering ambition in remote mountainous areas. It demonstrates how major infrastructure projects connect isolated communities with larger urban centers in the region.
Access to the bridge is via China National Highway 321, which connects the two cities and passes through the mountain landscape. Visitors should expect longer travel times due to the winding route through hilly terrain with elevation changes.
The bridge's structural design tapers gradually from the supports toward the center, adapting to the decreasing forces across the span. This optimization shows how engineers maximize material efficiency when dealing with extreme distances between supports.
