One of the largest concrete arch railway bridges ever built, the splendid Yelang River Bridge is the highest crossing on the 347 kilometer double track high speed railway line between Guiyang and Chongqing.

The central span of 370 meters is larger than any concrete railway arch outside of China except for the Almonte Railway Bridge in Spain. In China only the Beipan River?Bridge in Guizhou province's Qinglong county and the Nanpan River?Bridge in Yunnan province's Qiubei county have longer arches.
