We have received $429,540 Australian Government Black Spot road safety funding to improve safety at the intersection of Piggott Range Road and Upper Penneys Hill Road, Onkaparinga Hills.

The project was developed in response to concerns raised by residents and a history of crashes at this intersection involving vehicles colliding with roadside hazards, one of which sadly resulted in the loss of life.

A plan for the intersection upgrade has now been developed. The upgrade will include, but is not limited to:

  • Changing the intersection priority so that the southern section of Piggott Range Road will need to give way to traffic travelling between Upper Penneys Hill Road and the north-eastern section of Piggott Range Road.
  • Reconfiguring the intersection so that it meets in a T-configuration.
  • Widening the roadside shoulders.
  • Potential guardrails to protect vehicles from roadside hazards if required.

Due to layout of the site this upgrade cannot be completed without tree removals, and up to seven trees have been identified for removal. All of these trees are protected by the Native Vegetation Act 1991 (the Act), which requires a formal application process and approval from the Native Vegetation Council.

Under the Act, the approval process includes the planting of new trees and other environmental restoration work to offset the impact of the tree removals.

Wherever possible we avoid removing trees to facilitate a project however in this case, the upgrade can’t be completed without tree removals and the intersection upgrade is in the interest of reducing road trauma.

Community consultation was undertaken between 21 August and 4 September 2023.
