zaha hadid architects completes world's longest single-mast bridge in taiwan

Danjiang Bridge spans the mouth of Taiwan’s Tamsui River between New Taipei City districts of Tamsui and Bali. The bridge opened as the world’s longest single-mast, asymmetric cable-stayed bridge, with a 920-meter-long span supported by one concrete mast rising 200 meters above the estuary. The main span measures 450 meters and carries a 71-meter-wide deck for motor traffic, pedestrian paths, and cycle routes, with space reserved for future Danhai Light Rail extension. The single-mast design concentrates loads into one vertical structure and a fan of cables, reducing disruption to the estuary below. Detailed modeling and mapping protect views of Tamsui River sunsets, and the support system is designed for earthquakes of magnitude 7 or above.

"At the mouth of Taiwan's Tamsui River, Zaha Hadid Architects' Danjiang Bridge now stretches between New Taipei City's districts of Tamsui and Bali. The bridge has opened as the world's longest single-mast, asymmetric cable-stayed bridge, bringing a new line of movement across one of the region's most visible estuary landscapes. The project is worth watching for its scale, but also for the way that scale has been handled. Commissioned as part of a wider infrastructure upgrade for northern Taiwan, it is expected to cut roughly twenty-five minutes from commuters' cross-river journeys while easing pressure on the Guandu Bridge, located further upstream."

"Taiwan's Danjiang Bridge runs across a 920-meter-long span, held by a single concrete mast which Zaha Hadid Architects designs to rise 200 meters above the estuary. Its main span reaches 450 meters, with a 71-meter-wide deck carrying motor traffic, pedestrian paths, cycle routes, and space for the future extension of the Danhai Light Rail network. That single-mast structure gives the bridge its distinctive silhouette. Instead of placing a sequence of supports through the riverbed, the architects gather the load into one vertical figure and a fan of cables, reducing disruption to the estuary below."

"From the shore, the mast reads almost like a marker in the landscape, tall and slim enough to leave much of the horizon open. This was central to the original design approach, which used detailed modeling and mapping to protect views of the Tamsui River's well-known sunsets. Zaha Hadid Architects' Danjiang Bridge crosses the mouth of Taiwan's Tamsui River"

"The bridge also has to deal with Taiwan's seismic conditions. Its support system is designed for earthquakes of magnitude 7 or above, using pier supports,"
