Truro Bypass Project

The Australian and South Australian governments have committed $202 million (80:20) to fund the design and construction of a bypass at Truro which will divert heavy traffic along the Sturt Highway out of Truro’s main street, improving safety and amenity, as well as freight efficiency. The Department for Infrastructure and Transport is currently in the early design stage of the project.

Concept Design

A concept design for the Truro Bypass alignment has been released for public consultation, as planning progresses on a solution to improve road safety, boost freight productivity and get 600 B-Doubles and road trains off Truro’s main street each day.

The indicative alignment, developed as part of the early design phase of the project, diverts the Sturt Highway to just north of the Truro township and across Accommodation Hill.

The final bypass alignment has not been decided. Site investigations and consultation with the community will be carried out first to inform the design. The final bypass alignment is expected to be announced in early 2022.

Construction of the Truro Bypass is expected to commence in early 2023 and be completed by 2025.

Next Steps

Investigation activities including environmental and engineering surveys and geotechnical investigations are currently occurring. This will help us build a comprehensive picture of the area and ensure the relevant technical information is taken into consideration. The locations selected for the ground investigation and engineering survey works do not necessarily correspond to areas that will be impacted by the project in the final design.

Community Engagement

A big thank you goes to the 100 people that attended one of our four Truro Bypass information sessions held at the Truro Oval on Tuesday, 12 October and Wednesday, 13 October 2021.

What we heard during the recent consultation period

Common points raised include:

  • the majority of attendees were positive about the proposed indicative alignment for the bypass and were happy to see the project getting started;
  • a large proportion of attendees said that they understood the need for the bypass of Truro township and to improve freight efficiency through Accommodation Hill, noting the existing safety and noise concerns of trucks using the main street of Truro;
  • in general, the attendees thought the information sessions were helpful and informative, and were glad to have knowledgeable staff who were able to answer questions;
  • the local community acknowledged the importance of the future sustainability of Truro businesses;
  • attendees provided a lot of useful local information about the topography of the landscape, local access, flood areas, and infrastructure;
  • the majority of residents would like to see the bypass alignment positioned far enough away from the township so that heavy vehicle noise is minimised;
  • lots of feedback was provided about ensuring that there are safe and accessible links to the existing Sturt Highway and other key roads;
  • local residents highlighted the noise issues that are present with heavy vehicles using the main street of Truro (Moorundie Street);
  • there were lots of great ideas provided around how to support and enhance the future vitality of the Truro township and community; and
  • many attendees gave feedback about maintaining and improving the condition of the existing Sturt Highway throughout the Truro Township and beyond.

What's next?

Further information will be provided to the community in the coming months. We will continue to engage with the community to inform the detailed designs for the project and throughout its delivery.

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.

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.
