​Marble Bar Road - Coongan Gorge Realignment

Jointly funded by the Australian and State Governments, the realignment of Marble Bar Road through Coongan Gorge will improve safety and efficiency for all road users travelling to the central Pilbara Region. Marble Bar Road provides access to a number of mining operations and local communities between Newman, Nullagine, Marble Bar and several aboriginal communities including Jigalong and Punmu. The four kilometre section of road through Coongan Gorge is currently a narrow winding section of road with steep descents, tight curves and restrictive sight distances.

As part of the WA Regional Freight Transport Network Plan this upgrade will significantly improve road safety and reduce transport vehicle operating costs and travel times.
