Project overview

The Newell Highway Program Alliance (NHPA) completed a new southbound overtaking lane at Mirrool, about 15 kilometres north of Ardlethan in May 2023.

Project information


Transport for NSW has partnered with BMD and AECOM to form the Newell Highway Program Alliance.

The strategic partnership will deliver 38 additional overtaking lanes in an estimated four years rather than the likely eight years it would take to fund and deliver this work using traditional procurement methods.

This innovative mode of delivery will result in approximately 60 kilometres of new overtaking lanes to improve safety, reduce travel times, allow more accurate travel planning and improve freight efficiency.

The new overtaking lanes are expected to provide around 33 minutes of travel time savings along the length of the Newell Highway from the Victorian to the Queensland border.


The new and southbound lane extends for about 1.5 kilometres along the highway, about 15 kilometres north of Ardlethan.

Work on the new overtaking lane was completed in May 2023.

Now completed, road users travelling on the Newell Highway north of Ardlethan will experience increased overtaking opportunities to help improve journey reliability.

Other benefits of the project include:

  • improved safety for motorists and road users
  • reduced travel times
  • more accurate travel planning
  • improved freight efficiency.
