Contracts have been awarded to deliver $150 million upgrades of the Mount Barker and Verdun Interchanges in South Australia
Bardavcol Pty Ltd has been awarded the contract for the upgrade of South Australia’s Mount Barker Interchange, while a joint venture between BMD and Leed will undertake the Verdun Interchange Upgrade.
The interchange projects aim to improve connectivity to the South Eastern Freeway and improve the capacity of the interchanges in response to existing and projected growth for Mount Barker and the Adelaide Hills area.
Upgrading the Mount Barker and Verdun interchanges on the South Eastern Freeway will improve safety and traffic flow for the thousands of motorists who travel every day between the city and Adelaide Hills communities, including Mount Barker.
Mount Barker Interchange will be upgraded to include a new three-lane bridge across the South Eastern Freeway for northbound traffic, the conversion of the existing bridge to accommodate three lanes of southbound traffic and a new shared use path, plus improved ramp capacity and new traffic signals to improve safety.

The existing Verdun Interchange will be upgraded to a full interchange, allowing access to and from the South Eastern Freeway in both directions to improve connectivity and traffic flow.
It will feature an eastbound entry ramp towards Mount Barker, and a new westbound exit ramp, which will cross under the existing westbound entry ramp and connect with a new roundabout at Mount Barker Road adjacent to Silver Road.
The total project cost to upgrade the Mount Barker and Verdun interchanges is $150 million, with the Australian government committing $120 million and the state government contributing $30 million.
This project will support approximately 260 full-time equivalent jobs per year during the construction period.
Major construction on the interchanges is expected to begin in late 2025 and be completed by late 2027.
