The Ankeng Light Rail Metro System (ALRMS) is a Design-Build (DB) construction project located in New Taipei City. The Anhsin Bridge (AB) is one of the major parts of ALRMS. The original concept from the client, the Department of Rapid Transit Systems (DRTS), New Taipei City Government, was to design Anhsin Bridge as a steel arch bridge, which inevitably would require construction of some piers in the river reservation zone. Also, a temporary access bridge would be necessary during the erection of the steel frame. All these would pose a harmful situation for the river flow. Considering environmental sustainability, the contractor proposed a sustainable construction method, the unbalanced cable-stayed design with truss frames (UBCSTF), to build the Anhsin Bridge. Without constructing piers in the river reservation zone, the pylon of the Anhsin Bridge was laid on a 5.5m thickness foundation supported by 42 2m-diameter bored piles. A friendly environmental achievement was made by adopting UBCSTF. In this paper, the authors will share the rare construction experiences with the Anhsin Bridge construction, and present the detailed design concept, construction, and environmental sustainability achievements in this project.
