Jin'an Bridge, Suspension bridge on Chengdu-Lijiang Expressway in Yongsheng County, Yunnan Province, China.
The Jin'an Bridge extends 1,681 meters across the Jinsha River with a main span of 1,386 meters and towers rising 230 meters above the canyon floor below.
Construction began in 2016 and the bridge opened to traffic on December 31, 2020, replacing a difficult mountain route that previously required one hour to traverse.
The bridge received the China Construction Engineering Luban Award in 2023, recognizing it as a symbol of modern engineering achievement in southwestern China's mountainous regions.
The bridge is located at postal code 674104 in Yongsheng County and connects Jin'an Town with Songping township along the G4216 controlled-access highway route.
The structure holds four world records including the longest span for a suspension bridge in a mountainous canyon and first use of full penetration welding for U-ribs.
