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.
