Transport for NSW consulted on a recommended corridor of land for the Outer Sydney Orbital for a possible future motorway and freight rail line. The consultation period finished on 1 June 2018.

Key benefits
A motorway and freight rail line corridor would:

• Provide for a major transport link between the North West and South West Growth Areas, connecting with the planned Western Sydney Airport and future employment lands.
• Support growing communities, businesses and the creation of new jobs in Western Sydney.
• Allow for freight to move efficiently and safely by rail.
