Victor Harbor Road Duplication


About the project


The Australian Government has announced $73.6 million in funding for the duplication of Victor Harbor Road, between Main South Road and Main Road, McLaren Vale.  In addition, the South Australian Government has committed $18.4 million to the project, bringing the total project funding to $92 million.

The McLaren Vale region and outer southern suburbs have seen notable growth in recent years and caters to significant tourism activity primarily related to the iconic wine region and associated viticulture and agriculture industries.

Approximately 23,000 vehicles use the road each day, including 7% commercial vehicles. Traffic has grown by an approximate annual average of 3% since 2011 and is expected to increase.  From 2014 until 2018, inclusive, there were 22 casualty crashes.

Traffic volumes and crash history between Main South Road and Main Road, McLaren Vale has reached a point where duplication of the road to dual carriageway is necessary to alleviate traffic delays and safety issues.

The duplication will:

  • improve travel times
  • improve safety
  • accommodate future growth
  • improve economic productivity.

Major works are planned to start in 2021/22.

DIT COVID-19 Response

To help safeguard the DIT project team and the community, we have implemented measures to manage the risks of, and our response to, contracting COVID-19.

These include but are not limited to, increased personal hygiene practices and limiting face-to-face contact.

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 794 880).

We encourage the community to register for email updates.

There will be no planned community events or information sessions until further notice.

What’s next?

We have received valuable feedback from community and business owners from the surveys and information sessions held in December last year. This feedback has been provided to our engineering and design consultants for consideration as the preferred concept is developed.

Investigation works to inform the development of a design will commence later this month which includes;
-Collection of topographical data by an aerial drone, utilising light detection and ranging (lidar), flying parallel to the road corridor to minimise distraction to drivers. The drone will avoid flying over private residences.
-Location of underground services utilising targeted pot holing methods.
- Geotechnical drilling, and
-Flora and fauna assessments along the road corridor. 

If access is required to any property, we will contact residents or business owners to obtain their permission.

Once these investigations have been completed and a preferred concept design has been determined, provide information about the outcomes of the study and the preferred design.
