Temporary steel bridges reimagined for social distancing

In response to the challenge of ensuring safe social distancing at large-scale outdoor events, structural engineers Elliott Wood and reForm Architects have developed a concept design for a reconfigurable elevated steel walkway to reduce crowd densities.

Originally conceived to enhance the visitor experience at major horticultural events, the Tree Line has been reimagined as a temporary structure that can be quickly erected and demounted and can be reconfigured for use across multiple sites and different types of event.

When implemented as part of a movement strategy, it will enable one-way circulation, reduce crowd density at ground level and support the implementation of social distancing measures.

The Tree Line is said to offer exciting new viewpoints for visitors and creative opportunities for event organisers. Inspired by the stem and leaves of a plant, the structure includes a meandering walkway with separate viewing platforms and access ramps at each end. The design is based on a transportable length, fully prefabricated offsite so that it can be erected quickly on site.

Gary Elliott, Co-Founder and CEO of Elliott Wood said: “In the short term these structures provide the events industry with a tool for reducing crowd density, longer term they add a new dimension to the visitor experience”

Nik Randall, Managing Director, reForm Architects added: “The beauty of the Tree Line is that it addresses the challenges currently faced by many events and takes that opportunity to enhance the visitor experience.”
