Fifteenth Avenue Upgrade
Project overview
The Australian and NSW governments are investing $1 billion to upgrade Fifteenth Avenue, with construction expected to begin in 2027.
Planning and design work has started on the priority section between Cowpasture Road and Devonshire Road, with Fifteenth Avenue to be widened from two lanes to four lanes, for a two lane (each way) carriageway. This transformation will improve the most congested section of the corridor, providing relief for the 22,000 motorists using the road each day whilst helping cater for the area’s growth which is expected to triple by 2036.

Timeline of the Fifteenth Avenue upgrade.
Key benefits
- safer roads for drivers, their passengers, pedestrians and bike riders
- connection to jobs, education, business and air travel
- improved traffic flows and less congestion along local community roads
- supporting a growing community.
What’s happening now
We know that road users and local community experience congestion and delays along Fifteenth Avenue now. Already over 22,000 vehicles per day travel along the congested two-lane Fifteenth Avenue. So, we are making improvements to ease congestion and improve safety, as we plan the Fifteenth Avenue Upgrade.
The safety improvements include:
- getting to the M7: a third lane added on Cowpasture Road, between Fifteenth Avenue and the M7. This will reduce weaving and congestion
- investigating improvements to pedestrian safety along Fifteenth Avenue
- improving line markings and signs on Fifteenth Avenue
- reducing speed limits to 60km/h on sections of Fifteenth Avenue
Future vision - the Liverpool to Airport Transit Corridor
In the future, we will transform Fifteenth Avenue into the Liverpool to Airport Transit Corridor. This will become a direct link to the Bradfield City Centre. We will do this by:
- further widening Fifteenth Avenue
- building a new road from the western end of Fifteenth Avenue to Bradfield Metro Link Road.
The vision is designed to bring equity to Western Sydney. It will become a reliable transport network connecting people to housing, jobs and economic opportunities in the new Bradfield City Centre and Western Sydney International Airport.
