China Opens World's Highest Bridge at 625 Meters

Engineering Marvel in Guizhou Province

China has officially opened the world's highest bridge, the Huajiang Grand Canyon Bridge, which spans a breathtaking 625 meters (2,051 feet) above the Beipan River in Guizhou province. This engineering marvel surpasses the previous record holder, the Duge Bridge, by 60 meters and stands nearly twice as tall as the Eiffel Tower.

The suspension bridge features a main span of 1,420 meters and total length of 2,890 meters, connecting the Liuzhi Special District with Anlong Special District. Construction began on January 18, 2022, and was completed after three years of intensive work in the challenging mountainous terrain.

Revolutionizing Transportation

The primary goal of this ambitious project was to dramatically reduce travel times in the economically depressed Guizhou province. What previously took two hours to cross the canyon now takes just two minutes, transforming regional connectivity and economic prospects.

'I am proud to have helped build the world's highest bridge,' said welder Huang Xingchu, one of the construction workers who contributed to this monumental achievement.

Smart Technology Integration

The bridge incorporates cutting-edge 'smart cable' technology featuring embedded fiber optic sensors that continuously monitor tension, temperature, and humidity. This advanced monitoring system ensures structural integrity and safety in the challenging mountain environment.

According to https://news.cgtn.com/news/2025-09-28/Huajiang-grand-canyon-bridge-Engineering-marvel-meets-tourism-1H1ZZWFsM8w/p.html, the bridge is also designed to boost tourism, featuring elevators that ascend 200 meters within the bridge towers for bungee jumping and skydiving activities.

Regional Economic Impact

Guizhou province, known for its rugged karst topography that historically isolated it from the rest of China, now hosts nearly half of the world's highest bridges. The Huajiang Grand Canyon Bridge represents China's continued investment in infrastructure to overcome geographical barriers and stimulate economic development in remote regions.

The bridge forms part of the Guizhou S57 Liuzhi-Anlong Expressway, significantly improving transportation links in an area where economic revitalization is a key government priority.
