Zaha wins Danjiang bridge contest

  • Comment

Zaha Hadid Architects has triumphed in an international competition for a new ‘landmark’ bridge over the mouth of the Tamsui River in Taiwan

The winning scheme, drawn up with German engineers Leonhardt, Andrä und Partner, will be the ‘world’s longest single-tower, asymmetric cable-stayed bridge’.

It uses just one 175m-tall concrete mast to support the 920m road, rail and pedestrian steel deck.

According to the practice the mast is designed to be ‘as slender as possible and is positioned to offer the best structural performance’ without interfering with views of the river.

The £165 million bridge will connect the island’s Tamsui and Bali districts and reduce congestion on the existing Guandu Bridge further upstream.

The structure will also allow for the extension of Danhai Light Rail Transportation (DHLRT) system over the Tamsui River to connect the town of Bali and the port and harbour with Taipei’s public rail network.

Once finished the bridge will complete Tiawan’s northern seashore highway system and reduce travel time between the two shores by around 25 minutes.
