Transport Network Planning Studies Program


The Department for Infrastructure and Transport (the Department) is responsible for managing significant transport assets across metropolitan Adelaide. The planning and funding of future transport infrastructure projects to create a safer, more reliable and efficient transport network is a critically important function in supporting the achievement of important social, economic and environmental outcomes.

In 2020 the State Government committed $10 million for the Transport Network Planning Studies Program (TNPSP). The TNPSP represents a pro-active and strategic approach to transport planning with the aim of creating a ‘pipeline’ of priority infrastructure projects ready for delivery.

The program includes a suite of over 30 transport planning studies across metropolitan Adelaide exploring future upgrades for key arterial roads, intersections, road corridors, greenways and public transport infrastructure. All studies are strategically aligned with the priorities outlined in the 20-Year State Infrastructure Strategy released in May 2020.

The outcomes of the TNPSP will help inform and guide Government decision-making on the funding and delivery of future transport projects. Thorough, strategic and coordinated planning will ensure our State’s transport network meets the needs of future generations and is an integrated network completing a long-term vision to enable South Australia’s growth.

The TNPSP is divided into the following four key areas and investment programs:

  • Moving Freight
  • Integrated Public Transport
  • Active Travel and Future Mobility
  • Keeping Connected

The program is being delivered by the Department in partnership with two Integrated Planning Partners (IPPs). These partners are: Arup and AECOM, and Aurecon and Mott MacDonald Joint Venture.

Road Corridor Planning Studies 

A key feature of the Transport Network Planning Studies Program are the Road Corridor Planning Studies being undertaking along six of Adelaide's key road corridors – Main North Road, Payneham Road, Portrush Road, Unley Road, Cross Road and Brighton Road.

A Road Corridor Planning Study looks at:

  • How people live, work, visit and travel along the road corridor;
  • Current challenges with how the road corridor functions; and
  • Potential opportunities to improve the road corridor for all users.

Central to each study is the understanding that roads are not about just about the movement of people and goods, but are also places where people live, work, and visit.

Stakeholder Engagement

Engagement with key stakeholders is critical to the success of this program. The Department is committed to listening to and partnering with stakeholders to understand local transport issues.

COVID-19 Response

The Department will continue to tailor community engagement opportunities in line with the latest COVID-19 advice from health authorities. The health and safety of the community is our highest priority. Face-to-face engagement opportunities may be limited and/or restricted. Engagement is crucial however, and we will aim to facilitate face-to-face engagement, including information sessions, where and when it is safe to do so.
