From 2011 to 2031, the population of Western Sydney will increase by around 900,000 people, with around half of all Sydney Basin residents expected to be living in the region within 25 years.
Preliminary analysis indicates that initial demand at Western Sydney Airport will be about 3 million passengers per year from commencement of airport operations in the mid-2020s.
Future development in Western Sydney, and at the Western Sydney Airport, is expected to generate additional travel demand that would eventually exceed the capacity of the existing road network.
Projects to upgrade
The initiative includes a suite of road projects including:
- upgrading The Northern Road to a minimum of four lanes
- building a new M12 Motorway to provide access to the Western Sydney Airport between the M7 Motorway and The Northern Road
- upgrading Bringelly Road to a minimum of four lanes
- building the Werrington Arterial Road linking the M4 Motorway and Great Western Highway
- a package of local road upgrades.
A project to upgrade The Northern Road is separately included on the Infrastructure Priority List. The Bringelly Road upgrade was formerly on the Infrastructure Priority List and is now under construction.
Separate initiatives on the Infrastructure Priority List address the servicing of Western Sydney and Western Sydney Airport with rail and other public transport, as well as the preservation of transport and pipeline corridors.
Proponent to complete business case development (Stage 3 of Infrastructure Australia’s Assessment Framework).
The New South Wales Government is developing a business case for the M12 Motorway component of the Western Sydney Infrastructure Plan. All other components of the initiative are under delivery, with initial stages complete.
