Happy Valley Drive Intersections Planning Study

About the Project

As part of the State Government’s election commitments, the Department for Infrastructure and Transport (The Department) is conducting a planning study to develop potential options for upgrades on Happy Valley Drive at:

  • Happy Valley Drive / Chandlers Hill Road Intersection; and
  • Happy Valley Drive / Windebanks Road Intersection.

There is currently no funding to deliver these proposed upgrades. Future funding decisions will be considered based on community feedback and further technical investigations.

Happy Valley Drive (north of Chandlers Hill Road) and Chandlers Hill Road are under the care and control of the Department for Infrastructure and Transport. Happy Valley Drive (south of Chandlers Hill Road) and Windebanks Road are under the care and control of the City of Onkaparinga. The Department will work in coordination with council through the planning process.
