Connecting the M7 Motorway with the Western Sydney International Airport and The Northern Road.

About the project

The NSW Government is addressing congestion, improving safety and providing more choice for how you move around all of Sydney.

The M12 Motorway is a 16-kilometre dual carriage motorway that will connect the future Western Sydney International (Nancy-Bird Walton) Airport with the M7 Motorway at Cecil Hills and The Northern Road at Luddenham. Construction of the M12 Motorway is expected to start from mid-2022 and be open to traffic before the opening of the Western Sydney International (Nancy-Bird Walton) Airport.

The M12 Motorway will also provide connections to the surrounding Aerotropolis and other growth and employment areas via the Sydney motorway network while reducing traffic on Elizabeth Drive and at key intersections.

NSW planning approval for the M12 was received on the 23rd of April 2021, and Commonwealth approval received on the 3rd of June 2021.


Proposal to widen the M7 Motorway

A Concessionaire of the M7 Motorway recently put an unsolicited proposal to the NSW Government to deliver the M7/ M12 interchange as part of a program to widen the M7 Motorway. The NSW Government is considering this proposal and how it might re-shape how the M12 Motorway is delivered.

The priority to create a connection between the M7 Motorway and the Western Sydney International Airport before it opens in 2026, remains. However, it may mean other sections of the M12 Motorway could be delivered in stages.
