Danjiang Bridge connects innovation with infrastructure in Taiwan

Taiwan’s Danjiang Bridge is on track for a May 2026 opening after crews installed its final steel decking segment, marking the completion of one of Asia’s most ambitious infrastructure projects.

The bridge will become the world’s longest single-tower, asymmetric cable-stayed bridge, stretching across the mouth of the Tamsui River north of Taipei. Designed by Zaha Hadid Architects and engineered by Sinotech Engineering Consultants and Leonhardt, Andrä & Partner, the structure features a 450-metre central span supported by a 200-metre concrete mast.

Valued at around US$405 million, the 68-month project aims to ease congestion by up to 30% on the nearby Guandu Bridge, currently the only other crossing over the river. It will also shorten coastal travel routes by linking expressways directly, removing the need for a 10-kilometre inland detour.

Beyond its engineering significance, the bridge is designed to integrate with the estuary’s landscape. ZHA’s single-mast design was chosen to preserve the iconic sunset views of the area while withstanding strong winds and seismic activity. Advanced 3D mapping guided the bridge’s placement to optimise both visual and structural performance.

Once complete, the bridge will support pedestrian, cycling, and potential light rail expansion, positioning it as a multi-modal transport asset for northern Taiwan. Structural load testing, lighting installation, and paving will take place before the official opening.

The Danjiang Bridge demonstrates how design and engineering can align to deliver resilience, connectivity, and aesthetic value on a global scale.
