Congestion-busting concept design for gateway to Adelaide

Monday, 31 July 2023

Reducing congestion and building traffic capacity are at the heart of the newly unveiled concept plan for the upgrade of the intersection of Adelaide’s Marion Road and Sir Donald Bradman Drive.

The $85 million project is being jointly funded, with the Australian and South Australian governments each contributing $42.5 million.

Both 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 upgrades will include new turning lanes on Sir Donald Bradman Drive in both directions, along with an extended left-turn lane on Marion Road (northbound) heading west onto Sir Donald Bradman Drive.

New bicycle lanes will be installed on all approaches, with pedestrian crossings to be upgraded to improve safety for cyclists and pedestrians, and to encourage active travel.

Other intersection improvements will include new LED road lighting, asphalt, drainage, kerbing and gutters.

The project also includes new public spaces around the intersection.

The concept plan for the works has been informed by extensive planning, site investigations, engineering surveys and engagement with key stakeholders.

Community feedback will play a key role in shaping the design of the landscaping and the new public open spaces around the intersection, with a view to addressing existing issues and creating a useable, enjoyable community space.
