M12 Motorway (Sydney)

The M12 Motorway, initially known as Western Sydney Airport Motorway, is a planned east-west motorway in Sydney, Australia, linking between the M7 Motorway and The Northern Road, as part of the Western Sydney Infrastructure Plan. The four-lane motorway is planned to be 14 km long and to be built at a cost of $1.75 billion (with both State and Federal funding). It is aimed at providing direct access from the M7 Westlink Motorway to the new Western Sydney Airport situated at Badgerys Creek.[2]

On 17 June 2014, as part of the State Budget, the NSW Government announced a $5.5 billion road package for Western Sydney. It includes $6 million for planning the Western Sydney Airport Motorway. The Budget is also the first time the name of the motorway was referred to.[3] However, in recent years, government media and press release simply refers it as M12 Motorway.

The project is currently in the planning stage, with major construction proposed to commence in 2022 and is expected to be completed prior to the Western Sydney Airport opening in 2026.[4][5] The motorway will have 4 lanes, with provision to be widened to 6 lanes. It will also be toll-free.[6]
