Corridor Protection SEPP

The corridors of land set aside for future transport or other major infrastructure are protected in Chapter 4 of the State Environmental Planning Policy (Transport and Infrastructure) 2021, which is also known as the Transport and Infrastructure SEPP.

Interim use of corridors

We are amending the Transport and Infrastructure SEPP to permit the temporary use of corridor land.

The aim is to allow economic, urban design and public space initiatives on corridor land before infrastructure is delivered.

We exhibited an explanation of intended effects from 22 August to 19 September 2022 and invited feedback. We are now considering your submissions.

Lower Hunter Freight Corridor

Transport for NSW has finalised the location of the Lower Hunter Freight Corridor between Fassifern and Hexham after consulting the community.

The NSW Government will reduce travel times and create a more reliable rail network for passengers and freight.

To support the finalised corridor, the Department of Planning and Environment has safeguarded the land from future development. The design and operation of the rail line will require separate approval.

Visit Lower Hunter Freight Corridor for more information.

Western Sydney rail and road corridors

In 2018, Transport for NSW proposed 5 corridors for future transport infrastructure. These will support the growing population of western Sydney. Transport for NSW exhibited a discussion paper and invited submissions.

Three corridors have now been finalised, one is being considered and one has been withdrawn.


Being considered

Outer Sydney orbital – stage one.


The corridor for the Bells Line of Road–Castlereagh connection has been withdrawn.
