Design and Construction of the Capilano Cliffwalk

The Cliffwalk at the Capilano Suspension Bridge Park in North Vancouver truly is a structure that hangs off a cliff. The 213 m long, 0.5 m wide steel walkway with timber decking is cantilevered some 3 m from the face of the cliff and considered to be the first of its kind in the world. It consists of a series of 8 bridges, 5 stairs, 7 platforms (two with glass decks) and a cable supported curved bridge that traverse the eastern face of the Capilano Canyon and only require 11 sq. m of foundation area. Rock fall risk management was identified as an early design constraint. To mitigate pedestrian exposure to any stray rock fall, the majority of the walkway is cantilevered from the rock face by 3.0 m. Rock management is also provided by the construction of a reinforced soil slope at the crest of the cliff, stabilizing the cliff face with rock bolts and the construction of rock fencing wherever the field testing of rock trajectories indicated. Construction access was very limited and the original design needed to limit the weight of individual members to allow erection using only manpower, with only the curved, cable supported steel bridge and a couple of the straight bridge segments requiring erection with a small crane.
