Guozigou Bridge, Cable-stayed bridge in Huocheng County, Xinjiang, China

Guozigou Bridge is a cable-stayed bridge with two towers and two cable planes carrying a steel truss girder, opened in 2011 on the G30 Lianyungang–Khorgas Expressway in Huocheng County, Xinjiang. Its deck stands 200 m above the valley floor, the two towers rise 209 m and 215.5 m, and the 700 m structure uses 17,000 tonnes of steel bolted to a tolerance of 2 mm.

The bridge opened on 30 September 2011, carrying the G30 Lianyungang–Khorgas Expressway and Asian Highway 5 across the Guozigou valley in Huocheng County. It was the first road cable-stayed bridge in Xinjiang and the first in mainland China with a double-tower, double-cable-plane steel truss girder. Its spiral alignment, shared with the Xiazigou Bridge, keeps gradients navigable on the expressway 180 m below.

The bridge is known locally as Talki Bridge (Telki köwrüki in Uyghur), a name used alongside Guozigou. It carries the G30 Lianyungang–Khorgas Expressway and Asian Highway 5 across the valley, and its spiral approach lets vehicles climb at a navigable gradient. It was the first cable-stayed road bridge in Xinjiang.

The bridge carries the G30 Lianyungang–Khorgas Expressway over the valley, so it is crossed by driving, not on foot. The deck sits 200 m above the valley floor and the main towers rise 209 m and 215.5 m. The approach road climbs in a spiral over the expressway 180 m below to keep gradients gentle for vehicles.

The bridge deck sits 200 metres above the valley floor, while the expressway it carries loops below it in a spiral, 180 metres lower, so that vehicles gain height at a gradient they can climb. Its two towers rise 209 and 215.5 metres, and the steel truss was bolted together to a tolerance of two millimetres.
