Road Traffic Noise Assessments

We provide advice on traffic noise considerations to Local Governments and land developers to help ensure compatible land-use development. The minimum standards we expect from acoustic assessment reports are provided in the Requirements for Road Traffic Noise Assessments fact sheet. These minimum standards are provided to consultants as recommendations in our advice.

Further information can also be found on the Supplement to Austroads Guide to Road Design - Part 6B page.

Environmental Incident Reporting and Investigation

An environmental incident is any event resulting from the activities of Main Roads, Contractors working on our behalf and third parties, which has the potential to cause, or has caused, an adverse effect on the environment, or has resulted in a complaint relating to an environmental issue. All environmental incidents must be identified, reported, investigated and reviewed. Appropriate corrective actions are to be undertaken and processes revised as appropriate to prevent recurrence.

The Environment Incident Reporting Form is to be used to report any environmental incidents to Main Roads and notify the Environment Branch.
