Zaha Hadid Architects won the Danjiang Bridge International Competition in Taiwan, which called for designing a bridge over the mouth of the Tamsui River that flows through Taipei. The cable-stayed design would use only one concrete structural mast to support the 920-meter long road, rail and pedestrian steel deck and is expected to become the world's longest single-tower, asymmetric cable-stayed bridge.
The winning proposal, designed in collaboration with German engineering consultancy Leonhardt, Andrä und Partner, is expected to increase connectivity between neighborhoods and reduce traffic on Taipei‘s local roads, while becoming a “conspicuous landmark against the backdrop of Tamsui’s famous sunset.”
Its central mast is designed to be as slender as possible without compromising on structural performance. The design tries to avoid impeding the navigability of the river and minimize its visual impact on views from popular viewing points along the riverbank. Among the most important design imperatives which resulted in this minimalist design, was the desire to comply with the protection programs of the estuary’s ecosystems-the single-mast design minimizes the presence of structural elements in the riverbed.
