High Productivity Vehicle Network Project

About the project

The Department for Infrastructure and Transport are developing a Strategic Business Case for a High Productivity Vehicle Network.

This network comprises a corridor from the South Australian and Victorian border through to the South Australian and Western Australia border. This includes the Eyre, Sturt, Augusta and Dukes Highways as well as connecting routes around Greater Adelaide and to Outer Harbour. This project has been identified in the Infrastructure Australia Infrastructure Priority List (2022).

The intent of the program is to maximise the efficiency of South Australia’s regional and intrastate freight network and the interstate supply chain connectivity to the north, south, east and western states and territories in Australia.

The scope of the Strategic Business Case will include:

  • Eyre Highway
  • Augusta Highway ​
  • Dukes Highway to the Victorian border ​
  • Sturt Highway to the Victorian border ​
  • Dublin to Outer Harbour
  • Connecting the Princes Highway and Port Wakefield Road – providing an alternative heavy vehicle route away from the South Eastern Freeway and Portrush Road

We know that the demand for freight across Australia is increasing. Improving our road network to accommodate larger heavy vehicles means we can have fewer, larger vehicles on our roads, rather than many smaller heavy vehicles.

This presents a range of cost, labour and environmental efficiencies that we are seeking to better understand.

Latest News

The recent Federal Infrastructure Priority Project review resulted in the withdrawal of funding for the Truro Bypass project.  The Truro Bypass project is now being incorporated into this Strategic Business case so it can be considered for future funding.

Stakeholder engagement

The HPV Network project is the evolution of four Strategic Freight Studies Strategic Business Cases that were undertaken in 2022. These sought to identify the improvements necessary to allow these vehicles to operate safely and efficiently on the identified routes.

The projects comprised:

  • Greater Adelaide Freight Bypass;
  • Murray Bridge to South East Link;
  • Swanport Bridge; and
  • Eyre Highway Widening and Upgrade Planning Study

Stakeholder engagement was undertaken to develop these Strategic Business Cases, and will continue to form part of the planning process.
