Duge Bridge, Cable-stayed road bridge in Guizhou Province, China

The Duge Bridge is a four-lane cable-stayed bridge on the Guizhou–Yunnan border, its 1,341.4 m length carried by a steel truss deck with a 720 m main span. Two pairs of light grey concrete pylons form H shapes, the deck passing between the columns, with white cables fanning from their upper sections. The Guizhou tower reaches 269 m and the Yunnan tower 246.5 m; the deck sits 565.4 m above the Nizhu River gorge.

Construction began in 2011 and the deck was joined on 10 September 2016; the bridge opened to traffic on 29 December 2016 at a cost of ¥1.023 billion. It held the record as the world's highest bridge by deck height from 2016 until 2025, when the Huajiang Canyon Bridge surpassed it. Guinness World Records recognised it in 2018.

The bridge's name was disputed: Yunnan officials proposed renaming it Nizhu River Bridge in 2016 because it crosses the Nizhu, not the Beipan, and other bridges already carried the Beipanjiang name. Guizhou refused, as the name had been approved from planning onward. Yunnan funded 52.24% (¥537 million) and Guizhou 47.76% (¥491 million).

The bridge carries the four-lane G56 Hangzhou–Ruili Expressway between Qujing and Liupanshui, on the Guizhou–Yunnan border near Duge town. The deck sits 565.4 m above the Nizhu River gorge floor, so the crossing is short but exposed to strong valley wind; the design reference wind speed is 26.03 m/s. The road is graded for 80 km/h with a 1.0% longitudinal slope.

The deck's 565.4 m height above the gorge made it the world's highest bridge from 2016 until 2025, when the Huajiang Canyon Bridge surpassed it. Its 720 m main span is the longest of any continuous steel truss cable-stayed bridge. The name was disputed: Yunnan proposed renaming it Nizhu River Bridge, since the span crosses the Nizhu, not the Beipan.
