The future Danjiang Bridge will be located at the mouth of the Tamsui River in Taipei, Taiwan, and will be 920 meters long, with a 450-meter cable-stayed section, making it the world’s longest asymmetrical single-tower cable-stayed bridge.
The construction of the bridge is part of a plan to improve infrastructure in northern Taiwan, increasing connectivity between different areas and alleviating traffic congestion, without disrupting navigation on the Tamsui River. The bridge will feature a four-lane roadway, a light rail line, and a pedestrian path with a bike lane and a crosswalk.
The choice of this type of bridge—a cable-stayed bridge with a single mast—is based on the fact that it minimizes visual impact: the design takes into account the sunsets over Tamsui—a major tourist attraction that can be viewed from various vantage points—ensuring that no structural element interferes with or obstructs these views. This single mast, 175 meters high, is designed to be as thin as possible without compromising its structural integrity.
Zaha Hadid Architects has won the international competition to design the Danjiang Bridge, in collaboration with Leonhardt, Andra and Partners and Sinotech Engineering Consultants. The construction of the bridge will require an investment of about 250 million dollars.
