Project snapshot

  • Start date of major construction: early 2020s
  • Expected completion date: before the opening of the Western Sydney Airport
  • Funding: Australian and NSW governments

Project background

The new 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 and is expected to serve the Western Sydney Aerotropolis and the South West Priority Growth Area.

Benefits

  • 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 Priority 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.

Key features

  • 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.

M12 Motorway Community consultation report

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.

M12 Motorway route changes

See the Summary report - Preferred corridor route.

Wylde Mountain Bike Trail

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.

M12 Motorway planning and environmental investigations

We have carried out detailed site investigations, including biodiversity, Aboriginal and cultural heritageand geotechnical. These investigations will inform the design of the project and assist with the preparation of the Environmental Impact Statement (EIS).

What happens next?

The EIS should be on display for comment in 2019. The EIS will address the potential impact of the M12 Motorway and outline measures to reduce and manage environmental concerns and issues.

Construction is expected to start in the early 2020s, subject to approval.
