A further $600 million will be invested in two major Western Sydney road upgrades, with work on Elizabeth Drive and Fifteenth Avenue now expected to begin in late 2026.
The funding will be split equally between the NSW and Australian governments, with each contributing $300 million. The investment is designed to bring construction forward by a year and expand the scope of both projects.
The Fifteenth Avenue Upgrade will receive an additional $400 million, taking total project funding to $1.4 billion. The Elizabeth Drive Upgrade will receive an additional $200 million, bringing total funding for that project to $1 billion.
Together, the two upgrades represent a $2.4 billion investment in road infrastructure supporting Western Sydney’s growing population, new housing areas, industrial estates and the future Western Sydney International Airport.
The Fifteenth Avenue project will upgrade the corridor between Cowpasture Road and Devonshire Road, delivering two lanes in each direction, safer crossings, improved connections to local roads and better access to Western Sydney Parklands. The additional funding will also support improved bus infrastructure and an extension of Edmondson Avenue into the project scope.
Planning will continue for a future dedicated bus corridor along Fifteenth Avenue.
The Elizabeth Drive Upgrade will include 1.5 kilometres of additional road duplication from South Creek to the M12 interchange with Western Sydney International Airport, as well as a major upgrade of the Elizabeth Drive and Martin Road intersection.
The project is also expected to improve access to the airport, nearby industrial estates and the broader Aerotropolis precinct.
Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King says the funding will support more efficient movement as airport activity increases.
“With airport operations ramping up over the coming months, Western Sydney’s upgraded road networks will soon be put to the test,” Catherine says.
“These additional upgrades… will mean people and goods can continue travelling in and out of the airport efficiently as traffic volumes increase.”
