Nandu River Iron Bridge
The Nandu River Iron Bridge (), also known as the Devil's Iron Bridge, Old Iron Bridge, and originally the Lu Palace Bridge (吕宫桥), is a partially collapsed, steel truss bridge over the Nandu River, in the north of Hainan Province, China. Opened to traffic in 1942, it was Hainan's first bridge over the Nandu River.
==History==
The bridge was built by the Imperial Japanese Army during the Second Sino-Japanese War to provide access to the land west of the river. On March 26, 1940, approval was given to begin design and construction.〔 The responsibility for the bridge's construction was given to the Japanese company Shimizu Group Contracting, with the steel frames built by Taiwan's Kaohsiung Shipbuilding Production and Installation.
The bridge is long, wide, and has a concrete deck. A cylindrical, concrete guard house remains at the eastern end with horizontal openings. The bridge was designed for a maximum useful lifespan of 20 years, and could carry 20 tons. After liberation, the bridge entered civilian service with a 10-ton load limit and one-way traffic only.〔
In 1984, the Qiongzhou Bridge was constructed approximately to the north (downstream). As the Nandu River Iron Bridge deteriorated and became dangerous, it was closed to traffic and preserved as a monument.
