Documentary on construction of Oujiang Beikou Bridge

The significant challenges faced in the design and construction of a multi-pylon suspension bridge in China have led to advancement in engineering knowledge and practice for similarly difficult projects in the future. Designing a reliable, durable, economically feasible, user friendly, aesthetically pleasing bridge that carries 12 lanes of traffic is a huge design challenge. It becomes even more so when significant technical construction and manufacturing considerations related to limited structural height are introduced, as well as large clearance requirements for navigation, a deep and soft subsoil layer, and high frequency of typhoons. Through the implementation of technological innovation, the construction of the Oujiang Beikou multi-pylon suspension bridge (also known as Oujiang North Estuary Bridge) in Zhejiang Province is progressing well, in spite of all these challenges. The use of technological innovation in the design and construction of Oujiang Beikou Bridge has enabled progression in the increase of structural stiffness for central pylons in multi-pylon suspension bridges as well as in the lowering of costs for these bridges. The construction phase overcame the difficulties of open-caisson construction on deep soft ground as well as the impact of several typhoons, not to mention the hindrance caused by the COVID-19 pandemic. Builders are currently working at full steam to carry out construction operations that will ensure that the bridge will be opened to traffic in 2022, as planned.
