The vision for BORR was to create road infrastructure around Bunbury that did more than just facilitate efficient and safer traffic flow. Using an urban design strategy, the project team created a vibrant vision that would appeal to residents and tourists visiting the South West.

The development of the urban design strategy came about through consultation with focus groups, including the Aboriginal Heritage Advisory Group, as well as community feedback through public surveys in July 2021 and September 2023.

The theme chosen for the urban design was the Noongar Six Seasons:

Within this theme, the artwork across the project bridges and noise walls will incorporate the various elements of the surrounding environment, being ocean, river, sky, earth, farmland, bushland and forest.

• To tell the story of the unfolding six Noongar seasons, six bridges along the alignment were selected.
• The Paris Road and Clifton Road interchange will showcase the warm sunset hues of Djilba.
• The Raymond Road interchange will display the earthy clay tones of the Collie River during Kambarang.
• The South Western Highway (north) interchange will reflect the vibrant farmland-inspired colours of Birak.
• The Mega-Bridge at Boyanup-Picton Road will display the season of Bunuru with orange, earthy shades.
• The Yalinda Drive bridge will show the green tones of bush and forest during Djeran.
• The BORR/Bussell Highway interchange will have the cool blue tones of a Makuru sunset amidst the darker blues of a stormy, seasonal sea.
