Case Study: Onslow Ring Road
The completion of Onslow’s new ring road is set to benefit residents, industry and local tourism. This will guarantee access to the town, even in cyclonic conditions.
The $14.1 million Onslow Ring Road project involved the construction of a new 3.5 kilometre entrance road into the Town of Onslow with all-weather access to the town site from the recently upgraded Onslow Airport. It is another important piece of infrastructure for the growing Onslow community.
Previously, the access road between the airport and Onslow was subject to flooding from storm surges after cyclones which hampered emergency services and prevented evacuations from occurring. To overcome this seasonal problem, the new road is constructed on higher ground and includes new intersections and remedial works on the existing Onslow Road.
The works were funded by the Chevron-operated Wheatstone Project, a major liquefied natural gas venture located 12 kilometres west of the town. The works form part of a State agreement with the Department of State Development and the Wheatstone Joint Venture.
We worked closely with Chevron, Department of State Development and the Shire of Ashburton to design and construct the road. We are continuing to work with stakeholders to upgrade the remaining 75 kilometres of Onslow Road over the coming years.
