Najiehe Railway Bridge, Railway bridge in Guizhou, China

The Najiehe Railway Bridge is a steel truss arch bridge crossing the Sancha River, a tributary of the Wujiang, between Zhijin County in Bijie and Qingzhen in Guiyang, central Guizhou. Its main span measures 352 metres, and the rail deck stands 305 metres above the water, or 285 metres when the Dongfeng Dam reservoir is full.

The bridge was completed in 2016 as part of a major railway project in Guizhou Province. It connected previously isolated regions along the Wujiang River and opened new transportation routes for people and goods in the area.

The bridge links isolated communities along the Wujiang River, giving residents access to jobs and schools in distant cities that were previously hard to reach. It has transformed daily life for people living on opposite sides of the river by shortening travel times significantly.

The bridge carries the Lindai-Zhijin railway over the Sancha River between Zhijin in Bijie and Qingzhen in Guiyang, so it is seen from the line rather than approached on foot. The deck stands 305 m above the water, dropping to 285 m when the Dongfeng Dam reservoir is full.

The construction used two 120-meter towers to create a highline system stretching about 458 meters for moving massive arch pieces. This temporary system allowed engineers to position each segment of the arch with great precision high above the river.
