Long-Span Arch Bridge Projects
Long-span steel box-girder arch bridges feature a composite system combining steel box girders with arch trusses. This design offers high overall rigidity and load-bearing capacity, making it suitable for long-span crossings over complex waterways such as rivers and estuaries. The steel box girders are prefabricated in sections at a factory and assembled on-site using a modular hoisting and splicing process, ensuring efficient and rapid construction and significantly shortening the bridge construction cycle. The lightweight steel structure effectively reduces the load on the piers and foundations.

Construction of Long-Span Steel Bridges
Core Features & Advantages
Long-span steel box-girder arch bridges employ a construction method involving prefabrication in sections and whole-structure hoisting. Components undergo the entire manufacturing process—including welding and painting—in the factory, with only assembly and structural conversion required on-site. Compared to traditional concrete bridges, this approach significantly shortens the construction timeline and reduces risks associated with working at heights and over water. The lightweight nature of steel box girders effectively reduces the scope of work for the substructure and foundations, significantly lowering the overall project cost.
♦ Extremely large-span crossing capability
♦ High strength and light weight, reducing the overall cost
♦ Attractive design, ideal for landmark projects
♦ Factory prefabrication with efficient and safe construction
♦ Excellent structural performance and durability
Applications
Long-span arch bridges are suitable for various water-crossing transportation projects requiring rapid construction, including bridges spanning rivers and waterways for expressways, national and provincial highways, and municipal roads. They can also be applied to projects such as dedicated railway lines, tourist access routes, and community bridges in reservoir areas, making them the preferred solution for the efficient implementation of modern long-span bridge construction.
