$120 million jointly funded (50:50) by the Australian and South Australian Governments.

About the project

We're constructing new on and off ramps for the Southern Expressway at Majors Road. This will make it easier for commuters in the southern suburbs to access the expressway.

We expect to complete this project at the end of 2025.

What's happening

As part of this project, we're making improvements for vehicles, cyclists and pedestrians. We're also working to minimise impacts to the nearby parks and properties.

Road improvements

  • New on and off ramps to the Southern Expressway. These will improve access to the Adelaide CBD, North South Corridor, southern suburbs and Fleurieu Peninsula.

  • New traffic signals at the junction of Majors Road and Adams Road. These will allow access to Sam Willoughby International BMX Facility and O'Halloran Hill Recreation Park.

  • Widening of Majors Road to 2 through-lanes in both directions. This improvement will span between the Southern Expressway and Lonsdale Highway/Ocean Boulevard.

  • Widening of Majors Road bridge to 3 lanes in each direction. There will be 2 through-lanes and 1 dedicated right-turn lane onto the expressway in each direction.

  • Direct access to the new interchange for emergency services.

Pedestrians and cyclists

  • Pavement rehabilitation and duplication along Majors Road up to Lonsdale Highway/Ocean Boulevard.

  • A new underpass at Majors Road ensuring continuous access to the Patrick Jonker Veloway.

  • Realignment of the Patrick Jonker Veloway to improve the path orientation and sightlines.

  • New shared used path on the southern side of Majors Road, connecting Main South Road to Lonsdale Highway (in conjunction with City of Marion).

  • Access to Sam Willoughby International BMX facility.

Impact minimisation and regeneration

  • Tree planting along the Shared Use Path next to Majors Road to improve amenity and achieve 50% shade coverage (upon maturity).

  • Minimal impact to Glenthorne National Park, and we're planting more trees.

  • Putting the powerlines underground along this section of Majors Road.

  • No impact to O'Halloran Hill Recreation Park or Glenthorne Farm.

  • A new plant nursery in partnership with Friends of Glenthorne.
