The New South Wales Government is investing an additional $300 million in the 2026-27 NSW Budget to fast-track upgrades to Fifteenth Avenue and Elizabeth Drive, two critical road projects for Western Sydney.
The State Government’s investment will be matched by the Federal Government, delivering a combined $600 million boost to accelerate progress.
The major investment will expand the scope of the projects and bring construction forward, with work on both projects set to begin in late 2026, a year earlier than planned.
The projects aims to ease congestion, improve safety and strengthen connections to the new Western Sydney International Airport.
Additional funding for the Fifteenth Avenue upgrade will enable key design improvements in response to community and council feedback, such as improved and integrated bus infrastructure, and enhanced road connections with access to surrounding residential and industrial estates.
The upgrade between Cowpasture Road and Devonshire Road will deliver two lanes in each direction, improve connections to surrounding local roads, enhance access to Western Sydney Parklands and provide safer crossings for local wildlife.
Planning will also continue for a future dedicated bus corridor along Fifteenth Avenue, supporting the region’s long-term public transport needs.

Meanwhile, additional funding for the Elizabeth Drive upgrade will deliver 1.5 kilometres of additional road duplication from South Creek to the M12 interchange with Western Sydney International Airport.
It will also deliver a major upgrade of the Elizabeth Drive and Martin Road intersection, supporting surrounding industrial estates and the growing ‘aerotropolis’.
The project has also been refined to deliver safer and more efficient intersections at key locations along the corridor including a new, signalised intersection at Clifton Avenue, improved bridge connections across Badgerys Creek and South Creek and reduce impacts on local business and community facilities.
“With airport operations ramping up over the coming months, Western Sydney’s upgraded road networks will soon be put to the test,” said Catherine King, Federal Minister for Infrastructure, Transport, Regional Development and Local Government.
“These additional upgrades will mean people and goods can continue travelling in and out of the airport efficiently as traffic volumes increase.”
These investments build on more than $7.4 billion that the State Government has funded for Western Sydney roads since 2023.
