Horrocks Highway Upgrades
The Horrocks Highway Corridor Upgrade is focussed on upgrading the 245 kilometres length of highway between Wilmington and Gawler, to improve safety, connectivity and freight efficiency, whilst importantly creating jobs.
Works include shoulder sealing, pavement rehabilitation, lane widening, sealing of local road approaches, new overtaking lanes and overtaking lane extensions, bridge upgrades, safety barrier, Audio Tactile Line Marking (ATLM) on edge-lines and centreline and improvements to the Gladstone rail corridor and level crossing.
To date, $94.8 million has been committed for improvements to the Horrocks Highway, which is jointly funded by the Australian and South Australian governments (80:20).
The funding programs include:
- $55 million from the Horrocks Highway Corridor program, which forms part of the $330 million South Australian Rural Roads (SARR) Package.
- $1.1 million from the first stimulus Targeted Road Safety Works, which forms part of the $144.5 million Road Infrastructure Safety Package.
- $38.7 million from the second stimulus works $315 million Road Safety Package.
Pavement Widening, Overlay and Shoulder sealing extension works between Wilmington to Murray Town along Horrocks Highway will cease during the Christmas break and continue from mid-January 2022.
The Wilmington to Murray Town project section is nearing completion, final surfacing commenced in late November and will be completed, along-with new line-marking in early 2022, weather permitting.
Speed restrictions will apply over the Christmas break, and road users are asked to use extra caution when maintenance workers are on site, follow the directions of traffic controllers and observe traffic signage and speed restrictions when travelling through the area.

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.
The project team will provide construction updates and work notifications via social media, letterbox drops, emails and the Project website. We are also available to speak via telephone (1300 103 456).
We encourage the community to register for email updates.
