The Fengyi Bridge located in Shaanxi Province in central China has opened for traffic. UK consultant Arup, which designed and engineered the span, said it’s the World’s Widest Multi-tower Cable-stayed Bridge
Furthermore, the project is the first major bridge in the Xi’an High-tech Industries Development Zone. Also, this 155-sq-km park is home to more than 100 of the world’s largest companies, including Samsung, Siemens, Honeywell, GE and IBM.

Size of the World’s Widest Multi-tower Cable-stayed Bridge
The bridge stretches a total length of 526m, has an impressive three towers and its 57m-wide deck carries a five-lane highway, as well as two pedestrian and bicycle paths, which also serve as viewing platforms. . Arup said it provided “total design services, ranging from architecture and landscape to structural design”. “ Moreover, our innovative solutions ensure that the bridge stands tall with its mono-pole shaped, structurally efficient towers reaching a height of 95m, while the fan-shaped distribution of cables blends harmoniously with the natural environment,” it said.
Additionally, It added that its design drew inspiration from the surrounding mountain peaks and the cable structure “pays homage to Xi’an’s silk industry, with its woven strands reminiscent of silk thread”.
Moreover, Xi’an was also the historic eastern terminus of the old Silk Road.
Similar Projects in Asia; World’s Longest Asymmetric Cable-Stayed Bridge
Construction is well underway for the Danjiang Bridge in Taiwan, bringing it closer to becoming the world’s longest asymmetric cable-stayed bridge. Danjiang Bridge stretches 920m across Tamsui River in Taiwan.
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. This is expected to enhance Taiwan’s northern coastal traffic network and improve accessibility to the port of Taipei and Taoyuan International Airport.
Completion Date of the Danjiang 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.
Peri, a leading supplier of formwork and scaffolding systems, is assisting with the provision of custom-made formwork and engineering solutions for the structure.
Additionally, the company designed a free form form work 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.
Lastly, 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.
