Plans are underway to construct the longest asymmetric cable-stayed bridge in Taipei, Taiwan: it is slated for completion in 2025

The Danjiang Bridge on Taipei Taiwan, is anticipated to claim the title of the world's longest asymmetric cable-stayed bridge upon its projected completion in 2025. Specifically, the bridge will be boasting a length of 920m, and it will be standing at 200m above the river’s surface. The plan is to link the Tamsui District in New Taipei City with the Bali District.

In 2015, the bridge designed by Zaha Hadid, won the Danjiang Bridge International Competition for its innovative asymmetrical design. The unique design of the pier of the structure required careful attention to meet strict safety standards. Therefore, Peri Peri, the supply provider of formwork and scaffolding solutions, is contributing by delivering tailor-made formwork and engineering solutions for the project.

The centerpiece of the bridge, the pylon, resembles an inverted "Y," metaphorically resting its "legs" in the river. Its futuristic appearance is emphasized by parallel stay cables running from both sides. Peri's involvement in constructing the pylon included furnishing custom-designed formwork solutions for concreting an area spanning 18,000m².

Furthermore, to achieve the desired futuristic aesthetic, Peri developed a specialized freeform formwork system for the project, enabling the construction of 3,000m² of the pylon's surface. Adapting to the pylon's ever-changing shape across 53 sections presented a significant challenge, which Peri addressed with versatile VARIO, SCS, and ACS systems tailored to varying geometries.

In all, it should be mentioned, that Zeng Wei-Cheng, Site Manager at KSECO, commended Peri's contributions, noting the project's smooth progress and consistently high efficiency. He reassured the team that any challenges encountered during the construction process would be adeptly addressed.
