Taiwan Unveils World's Longest Single-Mast Bridge
18 Jun
Summary
- The Danjiang Bridge is the world's longest single-mast, asymmetric cable-stayed bridge.
- Its design optimizes structural performance while preserving sunset views.
- The bridge connects Taipei's transport network and includes future light rail integration.
Taiwan has officially inaugurated the Danjiang Bridge, a significant infrastructure project spanning the Tamsui River in Taipei. This structure is recognized as the world's longest single-mast, asymmetric cable-stayed bridge, measuring approximately 3,018 feet. The design, conceived by Zaha Hadid Architects, prioritizes both structural integrity and the preservation of the natural landscape, particularly the sunset view for which the Tamsui River estuary is famous.
The bridge features a slender, 200-meter mast engineered to support its main span under extreme weather conditions without obstructing the sunset. This single-tower approach, along with an asymmetric design, responds to the unique geography of the riverbed and surrounding terrain. Engineers focused on minimizing piers in the water to protect the riverbed ecosystem.
Beyond its aesthetic and environmental considerations, the Danjiang Bridge is a crucial transport link. It connects Highway 2 with other major routes, aiming to alleviate congestion on local roads and nearby bridges. The bridge is also future-proofed, designed to integrate the Danhai Light Rail system, establishing it as a versatile multi-modal corridor.
