After an international competition, Zaha Hadid Architects has been chosen to construct the Danjiang Bridge — an entirely new crossing that will span the Tamsui River in Taiwan. Working alongside bridge specialists Leonhardt, Andrä und Partner, Hadid’s design is located at the mouth of one of Taiwan’s largest rivers, and will serve as a key part of the region’s upgraded infrastructure.
The project will not only increase connectivity between the city’s neighborhoods, but will also reduce through-traffic on local roads by linking two of the region’s main highways. The crossing will also alleviate traffic at the congested Guandu Bridge upriver, and enhance accessibility with the rapidly expanding Taipei Harbor, the region’s busiest shipping port.
The link will allow for the extension of the Danhai Light Rail Transportation (DHLRT) system over the Tamsui river in order to connect the town of Bali with Taipei’s public rail network. Flanked by the urban centers of Tamsui to the east and Bali to the west, the estuary is rapidly growing in popularity with both residents and tourists as a recreational area. Each day people gather to watch the sun setting over the Taiwan strait.
The cable-stayed design minimizes its visual impact on the natural surroundings by using a single concrete mast to support the 920 meter-long road, rail and pedestrian deck. It is believed that the crossing will form the world’s longest single-tower, asymmetric cable-stayed bridge.
Engineered to be as slender as possible, the mast is positioned so as not to obstruct the waterway, or obscure views of the impressive sunset. The single-mast system also ensures that the riverbed suffers a minimum of disturbance.
