The Preferred road corridor boundaries report (PDF, 3.59MB) provides an overview of investigations and community and stakeholder consultation undertaken for the future duplication of the Barton Highway.

It provides some detail on the environmental and corridor constraints of the project, the changes made to refine the concept design and the decision making process.

A submissions report is an appendix to the preferred road corridor boundaries report and summarises the issues raised through community and stakeholder submissions and provides responses to those issues.
