World’s Longest Asymmetric Cable-Stayed Bridge
Danjiang Bridge stretches 920m across Tamsui River in Taiwan.
Construction is well underway for the Danjiang Bridge in Taiwan, bringing it closer to becoming the world’s longest asymmetric cable-stayed bridge.
Spanning the Tamsui River on the outskirts of Taipei, Taiwan, the bridge minimizes its visual impact by using a single concrete mast to support its main 450-metre span with dedicated road, cycle, and pedestrian lanes.
Danjiang Bridge, stretching an impressive 920 metres across the river, was designed by Zaha Hadid Architects – which won the Danjiang Bridge International Competition back in 2015 for the design of the asymmetrical bridge.
On completion in 2025, the bridge will connect Tamsui District in New Taipei City with the Bali District across the river – decongesting other transport routes.

The new bridge is expected to ease traffic on local roads by joining two highways across the river, thereby reducing congestion by 30% on a bridge upstream.
This is expected to enhance Taiwan’s northern coastal traffic network and improve accessibility to the port of Taipei and Taoyuan International Airport.
One of the interesting features of the Danjiang Bridge is its pier, which rises 200 metres above the water surface of the river, and whose construction requires careful planning to ensure compliance with strict safety guidelines.

Peri, a leading supplier of formwork and scaffolding systems, is assisting with the provision of custom-made formwork and engineering solutions for the structure.
The company designed a freeform formwork system tailor-made for the Danjiang Bridge project to help achieve the architectural marvel’s futuristic look.
This aided the construction of over 3,000 square meters of the pylon’s surface, even as its shape kept changing drastically across 53 sections.
The use of multipurpose climbing systems further accelerated the site works, ensuring both safety and efficiency at every stage of construction.
As construction progresses, stakeholders eagerly anticipate the completion of the new bridge, poised to become a symbol of innovation and connectivity in Taiwan.
