Long sections of narrow pavement and single-lane bridges create conflict between heavy vehicles and other traffic between Broome and Kununurra 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 more reliant on available infrastructure for their productivity and wellbeing.
The issues associated with poor flood resilience, accessibility and safety are a threat to continued economic growth and improved social outcomes in the northern region of Western Australia.
The proponent identified a range of potential responses, including upgrades to alternative routes and improving other transport modes. Through a multi-stage assessment process, the proponent demonstrated that a program of upgrades to the Great Northern Highway is the most appropriate response to the problems identified.
A program of upgrades could involve widening existing narrow sections of the highway, upgrading flood-prone sections, strengthening bridges and other targeted and non-build improvements such as flood sensors to warn road-users.
Different options for program size, duration and sequencing should be developed, taking into consideration the highest priority needs and interdependencies between program components.
Proponent to develop and submit a business case (Stage 3 of Infrastructure Australia’s Assessment Framework).
First added as a Stage One proposal 1/2/2020.
