Major works are currently underway at this Adelaide intersection which sees over 60,000 vehicles pass through it each day.
A total of $85 million has been committed to upgrading the Marion Road and Sir Donald Bradman Drive intersection which forms the meeting point of two major commuter, freight and public transport routes.
The Department of Transport and Infrastructure (DIT) says it is currently over capacity, creating significant congestion, particularly during peak periods.
Jointly funded by the Australian and South Australian governments, the upgrades will include new dedicated turning and through lanes, an extended left turn lane from Marion Road onto Sir Donald Bradman Drive towards the airport, and new bike lanes on all approaches.
“The improvements for travel through the intersection will reduce rat-running on adjoining streets and create a safer and more efficient journey for all road users,” said DIT, adding that between 2018 and 2022 there were 28 crashes at the intersection.
“Major construction works have ramped up, including kerbing, drainage works, road lighting, electrical infrastructure and pavement works.”
South Australian Minister for Infrastructure and Transport, Tom Koutsantonis added, “This intersection has been a significant pain point for commuters, locals and travellers over the last few years. With these upgrades, we’ll improve traffic efficiency, decrease queue lengths and reduce dangerous rat-running on surrounding streets.”
The upgrade is expected to be completed by early 2026.
Throughout the works, the intersection will remain open to traffic, with speed and lane restrictions in place.
