Designs have been released for one of the most important road projects linking large parts of South West Sydney and the Western Sydney International airport at Badgerys Creek.
The Fifteenth Avenue airport transit corridor project designs have now been put online for public feedback.
The designs, which outline the local access and movement changes, show how the community will safely access, travel on and move around Fifteenth Avenue in the future.
The project is being designed to make the road safer, more accessible and easier to travel while preparing for future growth.
To achieve this, there needs to be some changes to the way vehicles turn in and out of local streets and driveways.
The first stage of the project will focus on a section of Fifteenth Avenue between Cowpasture Road and Devonshire Road to allow for two traffic lanes in either direction, walking and bike paths, and planning for a future bus transitway.
Key changes outlined in the design include:
- Six new traffic light intersections including dedicated turning lanes and pedestrian crossings
- Left turn in, left turn out only access for all driveways and local roads including Herley Avenue and Craik Avenue
- New connection to Browns Road north
- A link road to safely access the local shops at West Hoxton and Twenty Seventh Avenue.
Current traffic volumes show about 22,000 vehicles use this stretch of road every day, and with volumes expected to double by 2036, these changes are critical for safety and future performance.
To provide relief for locals sooner, and as part of this early engagement, the project is also looking for feedback to reduce construction time frames and better understand the local environment.
The project is being fast tracked as a priority project after a joint commitment from the Albanese and Minns governments to invest $1 billion.
When completed, the upgrades will enable Fifteenth Avenue to be a key connection between Western Sydney Airport precinct, Liverpool and other parts of South Western Sydney.
Local MPs Anne Stanley (Werriwa) and Nathan Hagarty (Leppington) have welcomed the progress being made on this project.
“It’s an exciting day for my community to see the new road designs as the Albanese and Minns Governments work together to deliver this new road,’’ Ms Stanley said.
“Once complete, the upgrade will improve travel reliability and make it safer for people driving, walking, riding, or catching public transport.
“The road will also be future-proofed, so future Governments can increase capacity on the road as our region grows.”
Nathan Hagarty said the designs were part of a much needed project for the community.
“From what was a pipedream just a couple of years ago, the NSW Government has expedited plans to upgrade Fifteenth Avenue with a major investment to get the project moving,’’ he said.
“The new lanes and traffic lights will be critical to improving safety and ensuring cars and buses can flow smoothly along the route.”
Designs for Fifteenth Avenue can be viewed on the ‘have your say’ website at Fifteenth Avenue Upgrade | Transport for NSW and feedback can be provided between 11 November 2025 to 14 December 2025.
The community can also attend an online information session or talk to the project team in person at one of the pop-up sessions in Austral. Details are provided on the website.
The project is on track to invite tenders for a design and construction contract next year, ahead of major work getting under way in 2027.
It is excellent that they are improving the roads to access South West Sydney and the Western Sydney International Airport at Badgerys Creek. The cost of petrol is high for those living in the South West of Sydney. I am disappointed that neither the Federal nor the State Governments have considered Rail transport to South West Sydney and the Western Sydney International Airport at Badgerys Creek, by utilising the connectivity of the Leppington Line. The Southwest region is receiving a less favourable deal compared to other areas.
