​Gibb River Road Upgrade - Derby Highway to Fairfield-Leopold Downs Road

Gibb River Road is a 647 kilometre road between West and East Kimberley. The road is an iconic 4WD adventure route and major tourist attraction due to its rugged nature. It also provides access for numerous aboriginal communities, other remote communities, pastoralist and resource development.

The western end of the road (Derby) is predominantly sealed to various widths between 3.8 m and 6.2 m and is subject to relatively high traffic volumes. At the eastern end (Kununurra) a 33 kilometre section from Great Northern Highway and El Questro is sealed. 

The remaining 504 kilometres is unsealed except for high maintenance sections (mainly floodways and ‘jump-ups’). Annual maintenance and safety improvements are undertaken as funding permits.

Latest news

Upgrades were completed on a 53 kilometre section between Bungarun Road and Blina Road between 2015 and 2018.

Project development activities are underway with plans to construct and seal sections of the road between Kimberley Downs Road and Fairfield-Leopold Downs Road over next three years, depending on funding availability.

Scope of works

We are upgrading Gibb River Road between Derby Highway and Fairfield-Leopold Downs Road, which includes:

  • Sealing sections to 8 metres wide with improved drainage facilities and increased sight distance
  • Reconstruction of existing narrowed sealed sections
  • Road realignment, drainage improvements, installation of culverts and floodways


The project has been assessed and approved by the Department of Water and Environment Regulation under our CPS 818 purpose permit.

Environmental Impacts will be managed under a Construction Environmental Management Plan and a Revegetation Plan.


We have obtained clearances for the upgrade works in consultation with the Warrwa Native Title Claimants.


​Key benefits

  • Improved road safety
  • Reduced commercial transport costs
  • Reduced road closures due to flooding
  • Reduced maintenance costs
  • Improved access for Aboriginal communities and tourism
