M12 Motorway from M7 motorway To Western Sydney Airport

The M12 Motorway, initially known as Western Sydney Airport Motorway, is an under-construction 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.

The motorway began construction in August 2022 and is expected to open prior to the Western Sydney Airport opening in 2026.
The M12 Motorway will run between M7 Motorway and The Northern Road, including an exit to the access road towards the Western Sydney Airport. The motorway will have 4 lanes, with provision to be widened to 6 lanes. It will also be toll-free.
The existing road, Elizabeth Drive, is a two lane, single carriageway road linking the Hume Highway at Liverpool, with The Northern Road at Luddenham. It is one of several key thoroughfares in Western Sydney. The new motorway will run parallel to Elizabeth Drive.
