The Griffiths Pedestrian Bridge is Burnaby’s first architecturally detailed and creatively engineered pedestrian overpass. The City of Burnaby commissioned our firm and Fast + Epp to design a multi-use bridge that would be safe, accessible, low maintenance, aesthetically pleasing, and economical to construct using a similar budget to a conventional concrete post-and-beam structure.
The 12-foot-wide, 65-foot-long bridge spans Griffiths Way in south Burnaby. The elegant, visually arresting structure consists of an HSS structural frame suspended from a hollow steel tube arch with stainless-steel cables. A thin concrete deck rests on the frame, following an S-shaped path to allow for an offset in the right-of-way at either side of the street. As a result, the architectural and structural frame are skewed in plan, introducing a gentle shift in the angle of suspension cables over the length of the span.
An 8-foot-high stainless-steel mesh screen, supported by curved steel stanchions, offers protection along the main span. On the approach spans, the stanchions are reduced to five feet, with a guard of stainless-steel cables. Wooden handrails run the length of bridge.
