South Australian Rural Roads Safety Package

The Australian and South Australian Governments are funding a $143 million package, $114.4 million from the Australian Government and $28.6 million from the State Government, focused on road safety outcomes on the regional and rural South Australian road transport network.

Safety treatments to be undertaken as part of this package include:

  • overtaking lanes,
  • shoulder sealing, and
  • other safety upgrades, such as audio-tactile marking, on eight country roads.

The package of works will:

  • improve road safety
  • improve travel times
  • enhance connectivity between people and places, business and markets.

Overtaking lanes

As part of this focus on rural road safety $47 million has been allocated to construction of overtaking lanes to improve safety on regional roads with a commitment of $37.6 million from the Australian Government and $9.4 million from the State Government.

Additional overtaking lanes will be constructed on the following roads:

  • Augusta Highway between Lochiel to Crystal Brook, three new overtaking lanes
  • Long Valley Road between Wistow and Strathalbyn, one new overtaking lane
  • Victor Harbor Road between Crows Nest Road and Victor Harbor, one new overtaking lane
  • Lincoln Highway between Whyalla and Port Augusta, two new overtaking lanes
  • Riddoch Highway between Keith and Penola, three new overtaking lanes.

Overtaking lanes improve road safety by providing and encouraging safe overtaking opportunities and reducing driver frustration from drivers not being able to overtake slower moving vehicles.

The project is currently in the planning and design phase with construction works expected to commence in the 2021-22 financial year.

Shoulder sealing

As part of the Rural Roads Safety Package, $26 million has been allocated to shoulder sealing to improve safety on regional roads. This commitment, $20.8 million from the Australian Government and $5.2 million from the State Government, is part of the $1.115 billion funding announced in the 2019-20 State Budget for regional roads and infrastructure.

Shoulder sealing improves road safety by providing a recovery area for errant vehicles straying from the main carriageway. Road safety research shows a 40% reduction in off road and head on crash rates after implementation of shoulder sealing.

Roads for shoulder sealing:

  • Playford Highway
  • Aldinga Road (Aldinga - Willunga)
  • Maslin Beach / Tatachilla (Maslin Beach - McLaren Vale)
  • Black Top Road
  • Marrabel Road
  • Stott Highway (Angaston - Loxton)
  • Taylorville Road (Taylorville - Waikerie)
  • Goyder Highway (Burra - Renmark)
  • Cadell Valley Road / Ramco Road (Cadell - Waikerie)
  • Karoonda Highway (Loxton - Murray Bridge)
  • Spencer Highway (Moonta - Maitland)
  • Wilkins Highway (Warnertown - Jamestown)
  • Blyth Plains Road (Blyth – Halbury)

The majority of the shoulder sealing program is anticipated to be completed in mid-2020, while the Playford Highway (Kangaroo Island) is due for completion in late 2020, weather permitting.

COVID-19 Response

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.
