The Newell Highway is part of the National Land Transport Network. It is the principal inter-capital freight route between Melbourne and Brisbane, and is a critical link for regional producers in central and western New South Wales. Freight movements on the corridor are expected to grow strongly, supported by robust population growth in both Melbourne and Brisbane.

The efficiency of the route is constrained by localised congestion and flooding, deteriorating pavement and a lack of overtaking opportunities. Road alignment in several sections is also unsuitable for some High Productivity Vehicles.

These factors constrain freight productivity by increasing travel times and the number of vehicle journeys required, as well as reducing freight reliability.

Potential options

The proposal seeks to improve several sections of the highway to support safe High Productivity Vehicle access, and improve safety and reliability.

The proposal will also consider first/last mile issues faced by High Productivity Vehicle operators in the corridor.

Realignment of a 6.5 km section of the highway at Trewilga was completed in February 2018.

Road widening from Boggabilla to Goondiwindi is complete, with road widening from Coonabarabran to Narrabri in progress.

Construction is also in progress on heavy duty pavement south of Boggabilla, the upgrade of the intersection with Mitchell Highway at Dubbo and on a program to deliver around 30 overtaking lanes.

Planning is in progress for a range of further works:

  • bypasses of Parkes and Coonabarabran
  • heavy duty pavement provision (North Moree, Narrabri to Moree)
  • new Dubbo Bridge and realignment
  • additional overtaking lanes
  • improved flood immunity.

The NSW Government completed the Newell Highway Corridor Strategy in June 2019 and is progressively developing business cases for each element of this proposal.

Next steps
