The orbital is currently in its early stages of planning, with the corridor alignment to be decided. Currently, land is reserved for this project.[3]

Alignment

The Outer Sydney Orbital has been split into a few stages for separate corridor identification:

History

As part of economic development of Western Sydney, including the construction of the Western Sydney Airport at Badgerys Creek, The Northern Road was proposed to be upgraded to a grade separated motorway. The proposal, then known as the M9 Outer-Western Sydney Orbital motorway, would link the M31 Hume Motorway at Menangle with the Central Coast via Camden, Penrith and Windsor.[6]

As part of the State Budget 2014–15, the NSW Government announced a $5.5 billion road package for Western Sydney. It includes $4.6 million for planning the M9 Motorway. The preferred corridor for the motorway was expected to be announced later in 2014 before plans are made for reserving land.[7]

In June 2018, it was announced that the orbital will consist of a 10 km tunnel between Cobbitty to Cawdor, and the number of properties to be acquired will drop from 1,247 to 825, with the number of homes affected down to 200, to the relief of the community.[8] The orbital was originally planned to cut through the town of Cobbitty.
