Harbin Songhua River Extra Large Bridge Successfully Closed | QSM Cooperates with CCCC Second Harbor Engineering to Empower Northeast Infrastructure
On August 18, 2026, the Songhua River Extra Large Bridge, a key control project of Harbin Metropolitan Circle Ring Expressway, was successfully closed.
As a long-span cable-stayed bridge in Northeast China, the bridge stretches nearly 4,700 meters in total length, and the main navigational channel bridge reaches a height of 260 meters.
QSM Qiaxia supplied the full-bridge stay cables and corresponding construction services for this project. With mature complete-set technologies and reliable on-site service capabilities, the company provides solid core structural guarantee for this "Steel Rainbow Bridge".
Upon completion, the bridge will improve the expressway network of Harbin Metropolitan Circle, break regional transportation bottlenecks, and boost the development of cultural and tourism industries along the route.
