$1.2 billion dollar M12 project announced for Badgerys Creek

Posted by PlantMiner
The first piece of the Badgerys Creek puzzle has been put into place with a surprise $1.2 billion dollar announcement for a new motorway running between Cecil Hills and Luddenham. Roads and Maritime Services, on behalf of the Australian and NSW governments, is proposing to build a new motorway providing direct access to the planned western Sydney airport at Badgerys Creek and connecting to Sydney’s motorway network. 

Though the Bringelly Road upgrade was the first part of the Western Sydney Infrastructure Plan package to undergo construction, the M12 is one of the most significant, said the spokesperson.


The M12 Motorway is one of the major projects being developed as part of the WSIP. The Australian and NSW governments are jointly funding this 10 year, $3.6 billion investment program for western Sydney.

The Plan will deliver major road infrastructure upgrades to support an integrated transport solution for the region and capitalise on the economic benefits from developing residential and employment areas, and the planned western Sydney airport at Badgerys Creek.

What is being proposed?

The proposal is for an east-west motorway of about 14km between the M7 Motorway and The Northern Road which 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 South West Growth Centre and the Broader Western Sydney Employment Area (BWSEA).

The Roads and Maritime Services have said they are in the early planning stage for the new motorway, stating "we want to engage early with the community and our stakeholders to gather feedback which will be considered in our decision making and help with planning and design."

Scope of the project

An RMS spokesperson said the motorway would be completed by mid 2020, before the first flight leaves the airport.

Features Key features of the proposed M12 will be:

  • A motorway built for up to six lanes with a wide central median to separate opposing traffic flows
  • Grade separated interchanges at The Northern Road and at the planned western Sydney airport
  • A motorway-to-motorway interchange at the M7
  • Off-road shared pedestrian and cyclist paths. Project details will be updated as the project progresses



The proposed M12 will aim to:

  • Provide direct access from the M7 to the planned western Sydney airport at Badgerys Creek, and from the M4 via The Northern Road
  • Improve access to the South West Growth Centre and BWSEA
  • Increase road capacity for future growth and development
  • Improve traffic safety for road users
  • Increase pedestrian and cyclist infrastructure
  • Improve road freight movement to key commercial centres
  • Reduce the cost of congestion impacts to the community and business.
