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 Airport and connect to Sydney’s motorway network.  The proposed scope of works includes:

  • construction of a 16 kilometre four-lane motorway (two lanes each way) divided by a central median. The median will cater for a six-lane configuration, if required at a later date;
  • minimum design speed limit of 110 km/h;
  • grade-separated interchange at the Western Sydney Airport;
  • new at grade connection to The Northern Road;
  • motorway-to-motorway interchange at the M7 Motorway.


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 $1,246 million. The Australian Government is providing $997 million and the NSW Government is providing $249 million towards the construction of this project.


Construction is expected to commence in 2020 and be completed in the mid 2025.
