Following design changes to the $120 million Southern Expressway and Majors Road Interchange project in Adelaide’s south, work is now kicking off.
Majors Road is an important arterial road, providing a key connection between Lonsdale Road and Main South Road for around 13,200 vehicles a day.
This project will include new on/off-ramps for the Southern Expressway, which itself carries approximately 74,000 vehicles per day between Darlington and the Reynella Interchange.
“Majors Road is an integral part of our road network in Adelaide’s south and we’re happy to see works begin on an upgrade that will improve the experience for everyone using the road,” said South Australian Premier Peter Malinauskas.
“Projects like the Majors Road Interchange help the smooth and safe running of our road network, and we thank motorists and locals for their patience while we complete these works.”
The original concept design was updated following community feedback and additional technical analysis.
Additions to the design include the widening of Majors Road from the Southern Expressway to Lonsdale Highway/Ocean Boulevard to provide two lanes of traffic in both directions.
This section of road will also have power lines moved underground to provide further opportunities for increased landscaping and tree planting along Majors Road.
The design refinements also mean the on/off ramps will be shortened by approximately 100 metres to further minimise the impact on land and vegetation.
Federal Member for Boothby Louise Miller-Frost added, “I’m excited to see the progress on this interchange. Giving southern commuters direct access to the southern expressway will take commuter traffic off Brighton Road, meaning a shorter, safer trip for everyone.”
Short-term closures of Majors Road will be in place to complete the work.
The Southern Expressway will have localised speed restrictions while these works are undertaken.
Final project completion is expected at the end of 2025.
