Taiwan has reached a significant milestone in one of its most ambitious infrastructure projects as the final segment of the Danjiang Bridge’s steel decking was recently installed, connecting the east and west banks of the Tamsui River estuary for the first time. The completion of this crucial phase confirms the bridge’s highly anticipated opening date of May 12, 2026.
Designed by the late Pritzker Prize-winning architect Zaha Hadid, the Danjiang Bridge represents far more than mere infrastructure—it stands as a testament to Taiwan’s architectural ambitions and engineering prowess. The project holds special significance as one of the final designs that Hadid personally oversaw before her death in 2016, having been announced in 2015 during the height of her career.

Breaking Records with Signature Style
Upon completion, the bridge will claim the title of the world’s longest single-mast, asymmetric cable-stayed bridge, stretching 920 meters across the mouth of the Tamsui River near Taipei. The structure’s most striking feature is its towering 200-meter central mast—nearly 70 stories tall—which supports spans of 450 meters to the west and 175 meters to the east. This asymmetric design creates what CNN’s Oscar Holland described as bearing Hadid’s “signature” aesthetic, with “rounded edges and gently warped form” that remain distinctively hers even with the constraint of a single supporting mast.
The bridge’s artistic vision drew inspiration from Taiwan’s celebrated Cloud Gate Dance Theatre. President Lai Ching-te, who attended the completion ceremony in September 2025, noted that Hadid envisioned the structure as “a piece of dynamic and beautiful artwork that looks like it is dancing on the Tamsui River.” The president praised the project as “a work of art and a world-class project,” calling it “Taiwan’s glory.”
Engineering Innovation Meets Environmental Responsibility
Beyond its aesthetic achievements, the Danjiang Bridge represents groundbreaking engineering innovation. It will be Taiwan’s first bridge equipped with a damper system, enhancing its earthquake resistance to intensity 7—the highest level on Taiwan’s seismic scale. The single-mast design was strategically positioned not only for optimal structural performance but also to preserve scenic sunset views from popular riverbank locations while minimizing environmental impact on the estuary’s protected ecosystem.
The $766 million project addresses critical infrastructure needs by connecting the Tamsui and Bali districts while linking four major highways. Upon opening, it will significantly alleviate congestion on the existing Guandu Bridge, improving regional transportation and connectivity across northern Taiwan.
Final Stretch to Opening Day
The bridge’s construction involved sophisticated engineering challenges, requiring years of careful planning and execution. The recent installation of the final steel segment marks the culmination of intensive construction efforts, with remaining work focusing on final touches, including paving, lighting installation, cable inspections, and comprehensive load testing.
As Taiwan prepares for the May 2026 opening, the Danjiang Bridge stands poised to become not just a vital transportation link but a new landmark that embodies the island’s commitment to innovative design and engineering excellence. The structure will serve as a lasting tribute to Zaha Hadid’s visionary architecture while providing tangible benefits to millions of residents and visitors who will experience this remarkable fusion of form, function, and artistic expression spanning the Tamsui River.
