Garden Bridge , London, United Kingdom

A proposed pedestrian bridge with a garden in London.

The 366m Garden Bridge was designed as a new piece of transport infrastructure spanning the River Thames. It also included plans to incorporate a 2500m² planting area for tree and plant species on the bridge deck.

Arup's multidisciplinary team worked closely with Heatherwick Studio to develop the technical solutions needed to address the architectural challenges of this project. One of the team’s biggest tests was the selection of material for the bridge's exterior. Our materials specialists proposed the steel bridge and concrete piers should be encased in a thin layer of the marine alloy copper-nickel, roll bonded to steel to create a corrosion-resistant structural skin.

It was equally important to create an environment that would allow the bridge’s garden to flourish. The bridge was designed with significant soil depths, particularly over the proposed two piers, to allow the plant roots to grow and establish. Arup’s landscape architects and ecologists worked in conjunction with garden designer Dan Pearson, with advice from the Royal Horticultural Society, to ensure species suited to a bridge environment were selected.

On the 14th August 2017 the Garden Bridge Trust confirmed the project would not go ahead.
