Overview
- Crews installed the final steel deck segment in October 2025, physically linking both banks of the Tamsui River estuary.
- Zaha Hadid Architects’ crossing is billed as the world’s longest single-mast asymmetric cable-stayed bridge, spanning 920 m with a 200 m mast.
- The route is intended to relieve congestion and tie Highway 2 to Highway 15, Route 61 and Route 64, bolstering northern coastal connectivity.
- Remaining work includes asphalt paving, lighting and noise barriers, cable-force adjustments, and final load and safety tests.
- The design provides pedestrian and cycling lanes, allows for future Danhai Light Rail, protects the estuary, and incorporates a seismic damper system reported by Interesting Engineering.
