Elizabeth Quay Pedestrian Bridge, Perth - The Jewel of the Quay

The Elizabeth Quays twin arch pedestrian bridge artfully meanders across the entrance to the newly created inlet in the Perth CBD, Australia. The distinctive bridge completes a waterfront redevelopment that has transformed the foreshore into a busy promenade. Visitors to the precinct can now walk, run or cycle across the bridge enjoying spectacular views of the river and city in all directions.

The design brief was for a bridge that is simple, iconic, and transparent; cognisant of the outstanding potential to frame exciting views. In addition it had to allow access by ferries into the inlet and provide equitable access on the 5m wide and 110m long deck.

Arup architects and engineers worked collaboratively to optimize the design, challenge constraints and innovate in their delivery of the elegant curvaceous deck form and counterpoised inclined steel arches. The deck is in an S shape in plan comprising a steel box supported on one side by cables suspended from the 22m high arches. Concrete piers frame the navigation channel and continue the force lines from the arches to the water surface.

The bridge was successfully completed in early 2016, exceeding the client's expectations.
