Qinglong Railway Bridge, Railway arch bridge in Qinglong County, Guizhou, China

The Qinglong Railway Bridge, known in Chinese as the Beipanjiang Grand Bridge, carries the Guiyang–Kunming high-speed line across the Beipan River 1.2 km downstream of the Guangzhao Dam, where Guizhou's Guanling and Qinglong counties meet. Its deck sits 295 m above the water. The 721.25 m structure has a 445 m main span formed by a steel-tube concrete arch skeleton of about 5,300 tonnes in 40 segments, with approach spans on concrete piers.

The bridge was completed in 2016 as part of the new high-speed railway connection between Guiyang and Kunming. The project was an important step in connecting the mountainous province of Guizhou to larger transportation networks.

The bridge connects remote mountain villages and makes travel to the region simpler for people who live and work there. It has changed daily life by shortening journeys between isolated communities.

The location sits in a steep valley, so the best view of the bridge is from nearby vantage points. Those who want to see the structure from different angles should allow time to explore the surrounding area.

The arch was built by first pouring concrete into eight steel tubes, then encasing the whole steel skeleton in concrete before the deck columns were cast on top. Some 5,300 tonnes of steel went into 40 arch segments, with about 16,000 tonnes of rebar and 170,000 cubic metres of concrete in the bridge.
