Kirstenbosch Treetop Walkway

South Africa

2015

Shortlisted

The Centenary Tree Canopy Walkway is a curved steel and timber bridge that winds and dips its way through and over the trees of the Arboretum. Inspired by a snake skeleton, and informally called ‘The Boomslang’ (meaning tree snake), it is a low-maintenance, low impact sculptural raised walkway.

The main spine of the walkway is constructed from a galvanized tubular steel frame, with welded ribs and a light mesh giving the cross bracing, allowing the whole form to act as a bridge-spanning beam. Continuous shaped timber handrails ensure the safety of the visitor. The decking is stained, treated, slatted pine, placed on edge and spaced to accommodate the walkway’s curves.
