One of the highest concrete railway spans on earth, the Jiangjiehe Railway Bridge is part of a local freight route between Zunyi and Weng'an. The 337 meter concrete arch is located just a few hundred meters downstream of the 330 meter span Jiangjiehe road bridge that opened in 1995 as the highest bridge in China. The main arch rib of the railway span rises 61.5 meters for a 5.5:1 span to rise ratio.

The arch rib is composed of concrete-filled steel tubular skeletons encased in concrete. The composite girder consists of two I cross-sections of steel and concrete slabs connected by bolting and welding.

Both arch bridges cross over the deep waters of the 232.5 meter high Goupitan Dam reservoir that filled in 2009 and reduces the deck height of the railway bridge to approximately 160 meters above the full reservoir level. The road bridge is approximately 120 meters above the full reservoir level.

This Wengma railway was constructed primarily to transport phosphate reserves that are prominent in Weng'an County and make Guizhou a big exporter of fertilizer. The Wujiang River is one of the largest tributaries of the Yangtze River and has more high level bridges across its waters than any other waterway on earth. Only the Beipanjiang River has a more spectacular group of high river crossings in China even if the total bridge count is less.

Equally spectacular is the Xiangjiang Railway Bridge located 20 kilometers to the north on the same railway line. This double span extradosed bridge currently has the tallest railway bridge pier in the world at 161.5 meters.
