Main Road, Cherry Gardens

Project Background

We are delivering the Adelaide Hills Productivity and Road Safety (PRS) Package, which aims to upgrade some of the region’s key strategic arterial roads. The $150 million initiative, jointly funded by the Australian and South Australian governments (80:20), includes a range of road improvements to support economic growth, improve road safety and increase fire resilience in the Adelaide Hills area.

Between October 2022 and May 2023, the Department gathered feedback from the community to help inform the detailed design for safety upgrades on Main Road between Black Road and Chandlers Hills Road.

The Department has now further developed the design for this upgrade. The design has considered all community feedback while balancing technical considerations and site constraints. The final treatments will include:

  • road widening to achieve a consistent 3m width between Black Road and Chandlers Hill Road (where possible);
  • curve widening to achieve a consistent 3.2m width at the identified locations;
  • new road surface, improving skid resistance;
  • new safety barriers;
  • new road signage;
  • new line marking including centre line audio tactile line marking; and
  • drainage enhancements.

These treatments aim to improve road safety by reducing the risk and severity of road crashes.
