Dampier Highway Duplication

Balmoral Road West to Burrup Peninsula Road


This project has reached completion with both lanes in each direction now open to traffic. Balmoral Road West to Bayly Avenue was completed on 18 December 2012 and Bayly Avenue to Burrup Road was completed on 28 February 2013.

An opening ceremony was held on 5 March 2013 with representatives from Federal and State Governments, traditional owners, community representatives and other stakeholders taking part in the ceremony.

The project involved the construction of 12.3 km of highway with twelve intersecting roads along the section. Works included:

  • New carriageways of the duplicated highway
  • The construction of a bridge, built parallel to an existing bridge where the alignment of the duplicated passes across the Seven Mile Creek.
  • Minor improvements to pedestrian links and amenity; and
  • Improvements to the existing lanes of Dampier Highway to provide for an ultimate configuration offering 2 m sealed shoulders to allow for on-road cycling and a 9 m median.

Other issues considered include:

  • Further west, where it passes through Dampier Salt the alignment is affected by tidal movements (continuous water is present on either side of the existing carriageway for a distance of 2.6 km) and goes through rock cutting just prior to Burrup Peninsula Road; and
  • The modification of Dampier Highway and Burrup Peninsula Road intersection to make it a through-route. A seagull shape intersection with traffic signals is designed to improve safety and efficiency as well as protecting the identified Aboriginal Heritage sites in the area.



  • Improved travel time
  • Improved safety particularly allowing traffic from the side roads to join and leave the highway safely
  • Facilitate the development of the community of Karratha
  • Improve connectivity between Karratha and the industrial areas on the Burrup Peninsula



Highway Construction, Downer EDi Works and Albem Operations came together as Highway Works Albem Joint Venture (HWAJV) the successful contractor to undertake the Dampier Highway Duplication project, commencing in April 2011.

There were a number of options considered for the Dampier Highway - Burrup Peninsula Road intersection alignment due to Aboriginal Heritage environmental issues. An alternative alignment was chosen for the optional works by relocating the alignment from west of the existing road to east to avoid impact on Aboriginal sites and minimising the footprint to make sure the works had the least impact on the Aboriginal heritage sites.

Dampier Highway runs from North West Coastal Highway to the Parker Point Road intersection linking Karratha, Dampier and the Burrup Peninsula to the North West Coastal Highway.

Karratha's significant population and traffic growth in recent years has resulted from the expanding industrial activities on the Burrup Peninsula to North West Coastal Highway.

The growth in traffic has led to a number of issues associated with the operations of the town's road network, in particular, Dampier Highway. This project will address these issues and provide an efficient and safe level of service for road users.

Stage 1A was completed in 2008 with Stage 1B completed in October 2009. To find out more about these sections please visit the Dampier Highway Stage 1B page.
