纳界河特大桥
Liuchangxiang, Guizhou, China
1,017 feet high / 310 meters high
1,155 foot span / 352 meter span
2016
Upon its opening in 2016, the Najiehe Railway Bridge became the highest railway span on earth with a deck approximately 310 meters above the original level of the great Wujiang River. The 352 meter span steel arch is the highest structure on an east-west line that connects Guiyang city with Zhijin and Nayong to the west.
The Wu River is known as the Sancha River where the Najiehe Railway Bridge crossing is located. By far the largest and most famous river in Guizhou Province, the Wujiang also has more high bridges across its waters then any other river in the world. The single track railway line has several other high bridges along its route, most notably the giant beam span over the Wuzuohe River.
The all steel arch is unique for having two concrete T-beam balanced cantilever spans on either side with a span configuration of 48.85 and 48 meters on piers 56 meters tall. The smaller spans over the arch are 24.7 meters each while most of the approach spans are 32.7 and 24.7 meters.
The Najiehe Railway arch pieces were lowered into place using a highline with two towers 120 meters tall with a span of 458 meters. The rail level is at elevation 1229 meters and is approximately 259 meters above the full level of a reservoir formed from a downstream dam and approximately 310 meters to the original level of the Sancha (Wujiang) River.
