western sydney transport corridor motorway two


Transport for NSW is currently consulting on four recommended corridors for future transport infrastructure to support the growing population of Western Sydney.


The protection of these corridors is proposed to be achieved through a State Environmental Planning Policy (SEPP), an environmental planning instrument that addresses matters of State or regional environmental planning significance.


For further information on the recommended corridors go to Transport for NSW Corridor projects.


The NSW Government is currently seeking the community’s feedback on a Discussion Paper on the proposed State Environmental Planning Policy to protect Western Sydney Corridors (Pdf, 6.73 MB).

Planning for major infrastructure corridors


Planning for major infrastructure corridors is an important process to enable the delivery of large infrastructure projects needed in the future. Major infrastructure corridor planning can involve a number of phases over many years.


A new Planning guideline for Major Infrastructure Corridors (Pdf 1.18 MB) has been drafted to assist infrastructure agencies with the infrastructure corridor planning process.


This includes:

  • preparing the right information and detail for projects
  • an outline of when certain project information is needed
  • guidance on planning tools and the Department of Planning and Environment’s approach to using these tools.

The Guideline specifies the planning tools infrastructure agencies can use at each stage of the corridor planning process. It is not a set of rules, however provides a suggested pathway to planning for and protecting infrastructure corridors.
