The Chajiaotan Bridge is a suspension bridge between Xishui County in Guizhou and Gulin County in Sichuan, China, it is part of the S80 Gulin–Yibin Expressway and carrying traffic over the Chishui River.[3] It is one of the highest bridges in the world at 315 m (1,033 ft).[2]
Construction began in 2014 and the bridge opened in 2020.[4][5] The main span of the bridge is 1,200 m (3,900 ft) making it one of the longest ever built. Other high bridges on the Sichuan section of the Xugu expressway include Shilianghe, Luosizhai, Tiantanghe, Modaoxi and two crossings of the Gulin River.[2]
Chishuihe Bridge Chajiaotan is the last link along the 84-kilometre (52 mi) Xugu expressway that connects the city of Xuyong on the G76 with the city of Gulin and eventually the Chishui River gorge where it will connect with the Renchi expressway in Guizhou. Construction was completed in 2016 on all but the very eastern end of the expressway. Work was expected to start in 2017 on the second phase of the expressway including the Chishuihe Chajiaotan Bridge in addition to 12 kilometres (7.5 mi) of expressway in Guizhou Province. The span configuration will be 325–1,200–205 metres (1,066–3,937–673 ft) with a total length of 2,003 metres (6,572 ft) and a width of 27 metres (89 ft).[6] Some sources have a height of 323 metres (1,060 ft) but it is not clear if this is to the river surface or the bottom of the river.[2]
