Golden Grove Road Upgrade

The South Australian Government is upgrading a 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 (Kunzea Way) 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 were completed in late 2020.

The South Australian Government committed $20 million towards delivering Stage One.

Works included:

  • Roundabout at the junction of Golden Grove Road and Hancock Road;
  • Sheltered right turn lanes at most unsignalised 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 supported around 65 full time equivalent jobs over the life of the project.

Construction on Stage Two is underway, and roads are expected to be open to traffic by late 2021, weather permitting.

The South Australian Government committed $30 million towards delivering Stage Two which includes:

  • 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.
  • 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 will support around 70 full time equivalent jobs per year over the life of the project.

The works are being undertaken by South Australian based company, Civil & Allied Technical Construction Pty Ltd.

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.

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.

Bus Priority Treatments

The Department for Infrastructure and Transport (the Department) is improving public transport travel along Golden Grove Road by adding Bus Priority Treatments at identified intersections, as part of the $30 million South Australian Government funded Golden Grove Road Upgrade Project, Stage Two. The project objective is to improve the public transport travel time, accessibility, reliability and safety for all road users. The North East Public Transport Study identified the need for improvements to O-Bahn bus services in the area and determined that intersection upgrades with dedicated bus ‘priority lanes’ at the following intersections along Golden Grove Road were the preferred option to reduce travel time for commuters. Bus Priority Treatments will be installed at the following intersections:

· Golden Grove Road/ The Grove Way/ Yatala Vale Road.

· Grenfell Road/ Golden Grove Road.

· Milne Road/ Golden Grove Road.

· North East Road/Modbury Avenue/ Golden Grove Road

DIT Covid-19 response

The Department will continue to tailor community engagement opportunities in line with the latest COVID-19 advice from health authorities.

Face-to-face engagement opportunities may be restricted and we will continue to be guided by the advice of health authorities, with the health and safety of our stakeholders always our highest priority.

Engagement with community and industry is crucial and we will facilitate information sessions as much as possible to enable face to face engagement. It is important to assist in managing these events that you register as requested to enable physical distancing as much as possible.
