Project description

The project will involve the construction of a new east-west motorway between the M7 Motorway near Cecil Hills and The Northern Road at Luddenham.  The M12 Motorway will serve as the major access route to the Western Sydney International (Nancy-Bird Walton) Airport and connect to Sydney’s motorway network.  The proposed scope of works includes:

  • An east-west 16km motorway between the M7 Motorway, Cecil Hills and The Northern Road, Luddenham
  • A motorway built for four lanes (with provision for up to six lanes) with a central median to separate opposing traffic flows
  • A direct connection to Western Sydney Airport
  • A new at grade connection to The Northern Road with traffic lights
  • Provision for a motorway-to-motorway interchange at the M7 Motorway
  • Provision for a future grade-separated interchange
  • Connections to Elizabeth Drive near the M12/M7 interchange, and near the Western Sydney Airport entrance


The M12 Motorway, as part of the Western Sydney Infrastructure Plan, is expected to deliver significant travel time reductions and increased travel time reliability to road users and freight operators, by providing a high standard and efficient connection to the proposed Western Sydney Airport compared to using the existing road network.


The total cost of the project is $2,039 million. The Australian Government is providing $1,631 million and the NSW Government is providing $408 million towards the construction of this project.


Construction commenced in August 2022 and is expected to be completed in late 2025 prior to the Western Sydney International (Nancy-Bird Walton) Airport opening in late 2026.
