Eurella Initial Seal Project, Cobb Highway

Currently, 129 kilometres of the Cobb Highway is unsealed. The unsealed road sections require frequent maintenance that results in increased travel disruption. The Eurella Initial Seal project is located in the Central Darling Shire Council local government area (LGA), Barwon electorate. The project is between Ivanhoe and Wilcannia on the Cobb Highway (HW21). More specifically, 28.8km to 39.1km north of Ivanhoe.

Updates and announcements

February 2016

Sealing of the Cobb Highway at Eurella will start from 23 February 2016. There will be some temporary traffic changes to ensure the work zone is safe. Continued access for highway traffic will be via a temporary road on the eastern side of the Cobb Highway and will be operational 24 hours a day. See the February 2016 notification (PDF, 56Kb) for further information .

Project background

This project will improve flood immunity and provide an all-weather, more durable road surface for local residents and highway traffic. This will allow safe, efficient and more reliable journeys for travellers.

This section of the Cobb Highway currently cannot be accessed during wet weather because of the unsealed road surface. In prolonged dry periods, corrugations also become hazardous for road users. The excessive dust caused by traffic reduces visibility and also significantly impacts the health of road users.

The majority of this section of road uses causeways rather than box drains for drainage. When water flows over the causeways, the Cobb Highway is closed, stopping traffic completely and impacting local businesses and tourism.

Higher productivity vehicles like B-doubles and road trains have limited access to the road which impacts the overall efficiency of the local freight system.

These unsealed sections of the Cobb Highway also require frequent maintenance resulting in disruption to traffic. The frequent maintenance is expensive and also causes environmental degradation from sediment runoff.

Project objectives

The project will provide:

  • A new flexible road surface with a 20 year design life
  • A road surface above the level of the surrounding land so it is less impacted by wet weather.

Key features

The Eurella initial seal project will:

  • Provide an all-weather, more durable road surface to enable safe, efficient and more reliable trips for local residents and road users
  • Improve travel times and the reliability of travel during wet weather events
  • Improve liveability for local residents
  • Support economic growth and productivity for the region by improving access for freight vehicles and using local service providers where possible
  • Improve safety and security by reducing the risk of breakdowns, head on collisions and loss of control crashes
  • Significantly improve access to remote communities
  • Improve efficient routes for trucks
  • Reduce maintenance costs.

The Roadworks Contractor for the project is the Central Darling Shire Council (CDSC).

Community engagement

A Community and Stakeholder Engagement Plan has been developed for this project. It describes the communication and consultation approach and activities to keep key stakeholders and the community informed during the work.
