Designs released & community feedback sought for Mamre Rd Upgrade Stage 2
A new project milestone has been reached on Stage 2 of the Mamre Road upgrade between Erskine Park Road and Kerrs Road in Western Sydney.
Early designs and an environmental assessment have been released and the community is now asked to have their say on the Review of Environmental Factors (REF) that highlights project impacts including noise, traffic, air quality, flooding, biodiversity and heritage.
Community feedback will help shape the final design of the project while also reducing potential impacts.
A flythrough showing how the 6.1-kilometre route from St Clair to Kemps Creek will be developed to support the growth of local communities has also been released.
“This upgrade is about future-proofing Mamre Road to meet the demands of a growing Western Sydney.
“We’re turning a single-lane road into a safer, higher-capacity route that supports local communities, connects workers to jobs, and keeps traffic moving as the airport and surrounding areas continue to grow,” Minister for Roads Jenny Aitchison said.
“Western Sydney is booming, and this investment ensures our infrastructure keeps up.
“We want to get this right, and that means hearing from the people who use Mamre Road every day. Community Feedback on the environmental assessment is critical and will help shape the final design to best meet local needs,” Acting Minister for Western Sydney Courtney Houssos said.
The Mamre Road Upgrade Stage 2 is proposed to include:
- New traffic lights wit pedestrian crossings at Abbotts Road and Darrabarra Avenue
- Safer shared paths for walking and cycling
- Improved bus stops and drainage
- A smoother, safer drive with less congestion in peak times
Subject to planning approvals, main construction works are expected to commence in 2026 and be completed in 2029.
This project builds on the $290 million Mamre Road Upgrade Stage 1, which is already underway.
Mamre Road is a vital transport corridor that connects the Western Sydney Employment Area and the up-and-coming Western Sydney Aerotropolis and International (Nancy-Bird Walton) Airport.
About 20,000 vehicles pass through this route each day and this is projected to double by 2041. Upgrading this road will support more reliable travel as the region continues to grow.
The $1 billion Mamre Road Upgrade is jointly funded by the Australian and New South Wales Governments.
