Marion Road and Sir Donald Bradman Drive Intersection Upgrade

We're upgrading the intersection at Marion Road and Sir Donald Bradman Drive to make your journey safer and more reliable.

Marion Road and Sir Donald Bradman Drive are major commuter, freight and public transport routes with around 60,000 vehicles passing through the intersection every day.

The intersection becomes very congested with long queues especially during peak times.

This project will deliver:

  • Less time stuck in peak hour traffic
  • Better connection to Adelaide Airport
  • Safer pedestrian crossings
  • New bike lanes for cyclists
  • Less traffic rat-running through local streets with an intersection that works.

The Australian and South Australian governments have jointly committed $85 million (50:50) towards this upgrade.

This upgrade will support 125 full time equivalent jobs each year, boosting South Australia's economy.

Upgrade features

To make your journey safer and more reliable, this upgrade will include:

  • increased through-lanes on Sir Donald Bradman Drive heading west and new dedicated turning lanes on Sir Donald Bradman Drive in both directions
  • extended storage for the left turn lane onto Sir Donald Bradman Drive heading west
  • new LED road lighting, asphalt, drainage, kerbing and gutters
  • upgraded pedestrian crossings at the intersection and on Marion Road, improving safety for pedestrians
  • new dedicated bicycle lanes on all approaches, improving safety for cyclists
    urban design, landscaping and potential new public open space.

Project timing

Major construction will start in late 2024 and be completed in early 2026.

What's next

Input from the community will continue to play an important role to inform the detailed design of the urban and community open spaces. More information about these opportunities will be available in 2025.

Minimising impacts

There will be some impacts to trees and vegetation as a result of this upgrade however the project team was committed to reducing the impact through the detailed design process as much as possible. Existing vegetation, landscaping and the Boulevard of Honour have all being assessed and carefully considered. Read our Vegetation Fact Sheet for more information.
