Aboriginal interpretation urban design strategy

The M12 Motorway project team has developed an objective for the project "to create a unique and distinct identity interpreting the rich sense of place, aboriginal and cultural heritage" in its Urban Design and Landscape Plan which involves interweaving the Aboriginal narrative to enable using various components of the motorway to experience traditional Aboriginal stories.

A big part of this is Aboriginal Six Seasons. View or download the information sheet (PDF, 44.5Kb) to read more.

Project information

  • Start date of major construction: early 2022
  • Expected completion date: before the opening of the Western Sydney International Airport
  • Funding: Australian and NSW governments

The M12 Motorway would provide direct access to Western Sydney International Airport at Badgerys Creek and connect to Sydney’s motorway network.

The corridor route is an east-west 16 kilometre motorway between the M7 Motorway, Cecil Hills and The Northern Road, Luddenham. The motorway would provide increased road capacity and reduce congestion and travel times in the future. It would also improve the movement of freight in and through Western Sydney.

The M12 Motorway forms a key part of the Western Sydney Infrastructure Plan (WSIP). The WSIP is a joint initiative of the Australian and NSW governments to fund a $4.1 billion road and transport program for Western Sydney and is designed to capitalise on the economic benefits of the Western Sydney Airport as part of an integrated transport solution for the Western Sydney region.

  • Direct access to Western Sydney International Airport at Badgerys Creek from the M7 Motorway and the upgraded The Northern Road
  • Improved access to the Western Sydney Aerotropolis and the South West Growth Area
  • Increased road capacity for future growth and development
  • Improved traffic safety for road users
  • Pedestrian and cyclist infrastructure
  • Improved freight movement to key commercial centres
  • Reduced congestion impact on the community and businesses by providing more capacity.
  • An east-west 16 kilometre 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 median to separate opposing traffic flows
  • A direct connection to Western Sydney International Airport
  • A new connection to The Northern Road with traffic lights
  • A motorway-to-motorway interchange at the M7 Motorway
  • Provision for a future interchange connecting Mamre Road and Devonshire Road at the M12 Motorway.

Community information

Community members provided feedback in 2018 on the preliminary design and access strategy for the M12 Motorway.

The comments and our responses to them are detailed in the community consultation report.

The preferred M12 Motorway route will require changes to the existing Wylde Mountain Bike Trail located within the Western Sydney Parklands. We are working closely with the Western Sydney Parklands Trust and Bicycle NSW on plans to relocate the trail. The relocated bike trail is expected to be completed before construction of the M12 Motorway starts.

For more information about the Wylde Mountain Bike Trail visit the Western Sydney Parklands Trust website.

We have carried out detailed site investigations, including biodiversity, Aboriginal and cultural heritage and geotechnical. These investigations will inform the design of the project and contribute to the development of the Environmental Impact Statement (EIS).
