Golden Grove Road Upgrade

The South Australian Government is upgrading the 3.4 kilometre section of Golden Grove Road between One Tree Hill Road and Park Lake Drive.

The Golden Grove Road Upgrade Project will be delivered in two stages:

Stage One – One Tree Hill Road to the north side (Kunzea Way) of the signalised intersection of Golden Grove Road/The Grove Way/Yatala Vale Road.

Stage Two – Park Lake Drive to the north side of the signalised intersection of Golden Grove Road/The Grove Way/Yatala Vale Road.

Main construction works for Stage One started in December 2019, and are expected to be completed late 2020, weather permitting. The Stage One works are being undertaken by South Australian based company, Civil & Allied Technical Construction Pty Ltd.

The South Australian Government committed $20 million towards delivering Stage One which includes:

  • Roundabout at the junction of Golden Grove Road and Hancock Road;
  • Sheltered right turn lanes at most un-signalised junctions;
  • Indented bus bays;
  • On-road bike lanes in each direction;
  • Improved pedestrian facilities including new footpath (on western side) and pedestrian crossing facilities;
  • Kerb, gutter and drainage;
  • Targeted road resurfacing; and
  • New and upgraded road lighting.

Stage One is supporting around 65 full time equivalent jobs over the life of the project.

Impacts to vegetation removal have been assessed throughout the design development process and alternative options were considered and adopted, where feasible, to minimise impacts on regulated and significant trees, and other vegetation. For more information, refer to the Vegetation Fact Sheet.

On 22 October 2020, the South Australian Government announced a $30 million commitment to deliver both Stage Two of the Golden Grove Road Upgrade Project and key intersection upgrades at Grenfell Road/Golden Grove Road, Milne Road/Golden Grove Road and North East Road/Modbury Avenue/Golden Grove Road.

Stage Two works will include:

  • Golden Grove Road/The Grove Way/ Yatala Vale Road signalised intersection upgrade with:
    • Second right turn lane from The Grove Way approach;
    • Second through lanes on Golden Grove Road approaches;
  • Protected right turn lane at Highgrove Road junction;
  • On-road bike lanes in each direction;
  • Kerb and gutter, drainage, road resurfacing, as well as new and upgraded road lighting;
  • Improved pedestrian facilities including new footpath and pedestrian crossing facilities; and
  • Indented bus bays.

Stage Two will support around 70 full time equivalent jobs per year over the life of the project with early investigation works underway.

The Golden Grove Road Upgrade project team is working in collaboration with the City of Tea Tree Gully to deliver local government infrastructure, including footpaths, as part of this project.
