The 295m-long Chengdu West First Bridge has been completed. It crosses the Jiangxi River, a tributary of the Tuojiang River in China’s Sichuan province.
Designed by Zaha Hadid Architects (ZHA), the bridge has a 185m central span, with 55m secondary spans connecting to the river’s banks.
The cycle, road, and pedestrian bridge features two steel arches that rise from either side of the road deck, meeting at the crown. They help stabilise the structure against wind.
The bridge has a height-to-span ratio of approximately 1:6, with the bridge’s arches rising to 30m.
Many of the bridge’s elements are prefabricated, including the deck and girders.
ZHA’s digital structural testing concluded that the bridge would survive once-in-200-year weather events.
The bridge will open to the public once construction on the surrounding road is completed.
