"Zaha Hadid Architects was announced as the winner of the Danjiang Bridge International Competition in 2015. At the time, the design proposal sought to minimize the bridge's visual impact by employing a single concrete structural mast to support a 920-meter-long cable-stayed span. Construction began in 2019 on what would become the world's longest single-mast, asymmetric cable-stayed bridge. In October 2025, the final segment of the bridge's steel decking was installed,"
"Spanning the estuary of the Tamsui River, which flows through Taipei, the Danjiang Bridge forms a key part of the region's comprehensive infrastructure upgrade program. It was commissioned to reduce through-traffic congestion on local roads by linking Taipei's Highway 2 on the eastern bank with Highway 15, the West Coast Expressway (Route 61), and the Bali-Xindian Expressway (Route 64) on the western side. The project is also intended to strengthen the northern coastal traffic network by easing congestion on the existing Guandu Bridge, located 5 km upriver, and to improve connectivity between Tamsui District, Linkou District, downtown Taipei, New Taipei City, Taoyuan International Airport, and the Port of Taipei."
"ZHA's design allows for the future expansion of the Danhai Light Rail network across the Tamsui River, as well as pedestrian and cycling lanes. Using detailed 3D modeling and mapping of the estuary, the bridge's sculptural mast placement and the height of its road deck were precisely calculated to ensure safe passage for river vessels while minimizing obstruction of sunset views from popular vantage points along the river."
The Danjiang Bridge uses a single concrete mast to support a 920-meter cable-stayed span, minimizing visual and riverbed impact. Construction began in 2019 and the final steel-deck segment was installed in October 2025, confirming a May 12, 2026 opening. The bridge links Highway 2 on the east with Highway 15, Route 61 and Route 64 on the west to reduce through-traffic congestion and ease pressure on the Guandu Bridge. The design accommodates future Danhai Light Rail expansion plus pedestrian and cycling lanes, and employs 3D modeling to ensure vessel clearance and preserve sunset views while protecting the estuary ecosystem.
