Major works have commenced on the $90 million Grange Road, Holbrooks Road and East Avenue intersection upgrade in South Australia, to improve safety and ease congestion.
The project will be delivered by Seymour Whyte and is expected to be open to traffic by the end of 2025, with finishing works in early 2026, and will make it quicker and easier to move across Grange Road.
The project forms part of an $850 million package of broader network upgrades that are being undertaken as part of the River Torrens to Darlington (T2D) Project.
The intersection upgrade includes two through lanes on all approaches, two dedicated right-turn lanes for traffic going from Grange Road onto Holbrooks Road travelling south, a dedicated left turn lane on Grange Road travelling north, two dedicated right-turn lanes from East Avenue onto Grange Road travelling west.
A left turn slip lane from East Avenue onto Grange Road travelling east, two dedicated right-turn lanes from Holbrooks Road onto Grange Road travelling east, a left turn slip lane from Holbrooks Road onto Grange Road travelling west and a dedicated left-turn lane from Grange Road onto Holbrooks Road travelling south.
Other treatments include new and upgraded traffic signals, lighting, line marking, upgraded pedestrian crossings and installation of new dedicated bicycle lanes on all approaches.

The current T-junction of Grange Road, Holbrooks Road and East Avenue carries approximately 49,500 vehicles per day.
The upgrade is part of the suite of intersection upgrades linked to the River Torrens to Darlington (T2D) Project that will collectively ensure the road network functions efficiently, both during construction of the project and once it is completed.
As part of this project, a new Pedestrian Actuated Crossing was installed on Grange Road, between Hallett Boulevard and Coombe Road, following community feedback.
Tom Koutsantonis, Minister for Infrastructure and Transport said the intersection upgrade is something western suburbs commuters have long been hoping for.
“Constructing a new four-way intersection will relieve congestion, resulting in less time waiting at the traffic lights and improved safety and connectivity,” said Koutsantonis.
“Upgraded pedestrian crossings and new dedicated bicycle lanes will also improve pedestrian and cyclist safety at the intersection, and an indented bus bay on Holbrooks Road will improve bus movement through the intersection.”
Chris Kyriacou, Manager, South Australia for Seymour Whyte said he is excited to bring Seymour Whyte’s expertise to South Australia for the first time.
“This project represents our commitment to delivering innovative infrastructure solutions that enhance urban mobility, prioritise safety and connectivity, and foster sustainable growth,” said Kyriacou.
“The project will also generate local employment opportunities, contributing directly to South Australia’s economy and supporting the community.
“It’s a privilege to be part of Seymour Whyte’s expansion, particularly on a project that will enhance the daily lives of so many fellow South Australians.”
