Zaha Hadid Architects' Danjiang Bridge Opens as World's Longest Single-Mast Bridge in Taiwan

The Danjiang Bridge has officially opened in New Taipei City, Taiwan, and it's a remarkable feat, being the longest single-mast, asymmetric cable-stayed bridge in the world. It spans 920 meters across the Tamsui River, connecting the Tamsui and Bali areas. The bridge boasts a towering 200-meter concrete mast that supports a 450-meter main span, with a 71-meter-wide deck designed for cars, pedestrians, cyclists, and future light rail. Built to withstand earthquakes of 7.0 or higher, it includes various engineering features like pier supports and hydraulic dampers. Construction began in 2019, wrapped up with the final steel decking in 2025, and opened in May 2026, aiming to cut commute times by 25 minutes and ease traffic on the Guandu Bridge. The project was led by Zaha Hadid Architects, alongside Sinotech Engineering and Leonhardt, Andrä und Partner, who won a global competition in 2015. The design prioritizes keeping the beautiful sunsets over the Tamsui River visible.
