Construction on the Central and West sections of the new $2 billion, 16 kilometre toll-free M12 Motorway is underway. Please see the December 2022 Community update (PDF, 2.32 MB).

• Start date of major construction: August 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 $4.4 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.
• A new shared path between The Northern Road and M7 Motorway with lighting and connections to future and existing shared path networks.

The 6 kilometre west section of the M12 Motorway between The Northern Road, Luddenham and Badgerys Creek will be constructed by the CPB Georgiou Joint Venture.

This section includes:

• the airport interchange Elizabeth Drive interchange (flyover)
• a shared user path providing an active transport link
• bridges over Luddenham Road, Cosgroves Creek and Badgerys Creek.

The 7.5 kilometre central section of the M12 Motorway between east of Badgerys Creek and Duff Road, Cecil Park within Western Sydney Parklands will be constructed by Seymour Whyte.

This section includes:

• a shared user path providing an active transport link along the motorway, eastward to the M7 Motorway
• seven bridges, including bridges over South Creek, Kemps Creek, Elizabeth Drive and Range Road.

The M12 Motorway East section extends from Duff Road, Cecil Park to the M7 Motorway and will be constructed by John Holland with work expected to start in the second half of 2023.

This section includes:

• an interchange with the Westlink M7
• a new connection with Elizabeth Drive
• an upgrade of a small section of Elizabeth Drive with two lanes in each direction and a posted speed limit of 80km/h 
• the realignment of Wallgrove and Cecil Roads.

Wylde, Australia's largest combined mountain biking and BMX hub is now open and free to ride at Western Sydney Parklands.

Wylde was relocated to make way for the new M12 Motorway. Transport for NSW, Liverpool City Council and Greater Sydney Parklands worked together to design and construct the new Wylde facility for the community.

Thanks for the community who patiently waited during construction of the tracks and trails. We hope you enjoy the new riding experience!

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

In February 2023, the M7 Widening project received planning approval and will be delivered by WSO Co on behalf of Transport for NSW.

This component of work will be designed and constructed by John Holland along with the M12 East section.
