Adelaide Hills Productivity and Road Safety Package
We are delivering the Adelaide Hills Productivity and Road Safety (PRS) Package 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
- increase fire resilience in the Adelaide Hills area.
Works may include:
- pavement works
- road widening
- easing of tight curves
- shoulder sealing
- audio tactile line marking
- safety barrier installation
- junction upgrades
- vegetation management.

Community engagement
In October 2022 we sought feedback from the community about Main Road, Cherry Gardens. Then during November and December 2022, we sought feedback on the remainder of the Adelaide Hills Productivity and Road Safety Package.
The engagement focused on listening, learning and gathering local insights on experiences travelling along the key corridors and throughout the region. We got valuable feedback through face-to-face sessions, surveys, emails, and online submissions.
The insights from late 2022 inform our designs for safety upgrades across the Adelaide Hills PRS Package corridors.
Thank you to everyone who took the time to share their insights.
