The Griffiths Pedestrian Bridge is a 20 metre long and 3.5 metre wide bridge spanning Griffiths Way in south Burnaby.
Allnorth was hired as an advisor to help design the bridge, which is an elegant, visually arresting structure consisting of a hollow steel tube arch from which an HSS structural frame is suspended by 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-ways at either side of the street. As a result, the arch and structural frame are skewed in the plan, introducing a gentle shift in the angle of suspension cables over the length of the span.
A 2.4 metre 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 1.4 metres with a guard of stainless steel cables. Wooden handrails run the length of the bridge.
