New Mandurah Traffic Bridge

Landscape Planners provided landscape architectural consultancy for the Old Mandurah Traffic Bridge Replacement project, a $51million joint project between MRWA and the City of Mandurah. Built by Georgiou, the project involved the construction of a new four lane traffic bridge to the north of the old bridge, and demolition of the old bridge. Landscape Planners was part of a multidisciplinary design group including BG&E Engineers and Gresley Abas, working on urban design elements of the project including, the bridge structure, boardwalks, fishing platforms, artwork, as well as provinding visual and pedestrian connectivity to the surrounding Mandurah Estuary foreshore. Landscape Planners designed the interpretative fishing platform, sail shade, and seating utilising salvaged elements of the old bridge creating heritage and visual connections to the demolished old traffic bridge. The original bridges' eastern abutment was retained and enhanced with concrete and recycled timber seating, old bridge piers within the estuary were retained on both sides of the navigation channel, providing a visual cues to the old bridge spanning across the estuary to the retained western seawall. The sailshade form was designed to reflect water movement within the estuary below the fishing platform and new bridge.The fishing platform was reconstructed, utilising salvaged bridge timbers to reflect the original platform layout.

Landscape connections were provided to the eastern and western foreshores, skate park, and Mandurah Terrace, with 'esturay edge' landscapes created with riparian planting and beach spaces below the bridge.

The project was a finalist in the 2018 Western Astralia Engineering Excellance Awards.
