Danjiang Bridge to open 12 May 2026

The final segment of Danjiang Bridge’s steel decking has been installed, connecting the east and west banks of the Tamsui river estuary for the first time. Following this important milestone in the bridge’s construction, its 12 May 2026 opening date is now confirmed.

Spanning the mouth of the Tamsui River which flows through Taipei, Danjiang Bridge is the world’s longest single-tower, asymmetric cable-stayed bridge and is integral to the region's comprehensive infrastructure upgrading program.

On opening next May, the bridge will reduce through-traffic congestion on local roads by linking Highway 2 on the river’s eastern side with Highway 15, the West Coast Expressway (Route 61) and the Bali-Xindian Expressway (Route 64) on the western side of the river.

Danjiang Bridge will also significantly improve the northern coast traffic network by reducing traffic on the existing Guandu Bridge 5km upriver, easing travel between Tamsui District, New Taipei City’s Linkou District, downtown Taipei and New Taipei City, as well Taoyuan International Airport and the Port of Taipei. With dedicated pedestrian and cycle lanes, ZHA’s design also allows for the future expansion of the Danhai Light Rail network across the Tamsui River.

The Tamsui River estuary is an important natural ecosystem, bordered by the urban centres of Tamsui to the east and Bali to the west. The estuary has become a popular recreational destination for residents and tourists to gather to watch the sunset.

Engineered to optimise structural performance without impairing views of the setting sun, a sculptural 200-metre concrete mast has been designed to be as slender as possible while safely supporting the bridge’s 450-metre central span in extreme weather conditions and seismic events.

Determined by detailed 3D modelling and mapping of the estuary, the position of the bridge’s sculptural mast within the river and the height of its road deck above the water’s surface have been calculated to maintain safe passage for river vessels and minimise impeding sunset views from popular viewpoints along the river.  The single-mast design also reduces the structure’s impact on the riverbed in line with stringent programs established to protect the estuary’s ecosystem.

With the bridge’s structural components now complete, construction teams will begin laying asphalt on the road deck, install lighting, noise barriers and auxiliary facilities, as well as adjust cable forces and conduct structural load tests ahead of the 12 May 2026 opening.
