Zigui Yangtze River Bridge, Road and truss arch bridge in Zigui County, China

The Zigui Yangtze River Bridge is a road bridge with a truss arch design that spans the Yangtze River in Zigui County. It connects communities on either side of the river and functions as a major transportation route for the area.

The bridge was completed in 2019 and marks the most downstream crossing point over the Three Gorges reservoir basin. It united previously isolated communities and significantly improved transportation connections in this river region.

Zigui County is the hometown of the ancient poet Qu Yuan and the Han dynasty consort Wang Zhaojun. The bridge's arch form, likened to a rainbow, is meant to symbolize Qu Yuan's spirit, and its orange colour matches the county's navel oranges.

The bridge carries a four-lane first-class highway with a design speed of 60 km/h, and sidewalks plus sightseeing walkways were added on both sides of the carriageway at local residents' request. It begins east of Guojiaba town on Provincial Road S334 and crosses the Yangtze at the Bingshu Baojian Gorge; the wider Xiangxi River highway project runs 5.419 km to Xiangjiadian in Guizhou town on S225.

The deck sits 118 m above the reservoir at its maximum level of 175 m, while the arch crown reaches 176 m above the water. The bridge body is made of 23 steel truss segments, the heaviest weighing 263 tonnes and the lightest 33.4 tonnes.
