Long sections of narrow pavement and single-lane bridges create conflict between heavy vehicles and other traffic between Broome and Kunnurra on the Great Northern Highway.

In the wet season, regular road closures disrupt supply chains for industry and add to the cost of operating in the Kimberley Region. These road closures mean there are unreliable connections between local communities and poor access to essential services.

The 2019 Australian Infrastructure Audit found that communities and businesses in remote areas are reliant on available infrastructure for their productivity and wellbeing.

The issues of flood resilience, accessibility and safety are a threat to continued economic and social growth in the northern region of Western Australia.


The proposal involves improvements to address safety, pavement and bridge strength and width, culvert rehabilitation and flooding resilience on sections of the Great Northern Highway between Broome and Kununurra.
