Critical road link Mamre Road will be widened to two lanes in each direction as part of a $1 billion upgrade by the Minns and Albanese Governments to ease traffic and improve safety in Western Sydney.
Early designs and an environmental assessment for Stage 2 of the Mamre Road upgrade between Erskine Park Road and Kerrs Road have been released today, showing its transformation from suburban road to major arterial link across the west.
Also released was a flythrough that shows how the 6.1 km route from St Clair to Kemps Creek will be developed to support the growth of local communities. Some 20,000 vehicles currently use the route daily and this is expected to double by 2041.
Mamre Road is a key link to Western Sydney's growing employment areas, including the future Western Sydney International (Nancy-Bird Walton) Airport, and the upgrade will support more reliable travel as the region continues to expand.
This project builds on the $290M, 3.8 km Mamre Road Stage 1, already underway, and will improve the connection between the M4 Motorway and Elizabeth Drive.
The community has been asked to have their say on the Review of Environmental Factors (REF) which considers project impacts including noise, traffic, air quality, flooding, biodiversity and heritage. Community feedback on the REF will help shape the final design and reduce potential impacts.
The Mamre Road 2 upgrade is proposed to include:
- New traffic lights with 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
Pending planning approvals, construction is expected to get underway in 2026 with construction expected to be completed in 2029.
This is one of several major road projects transforming travel in Western Sydney, including:
- The new toll-free $2.1 billion M12 Motorway (opening 2026)
- $800 million in upgrades to Elizabeth Drive
- A $1 billion overhaul of Fifteenth Avenue between Cowpasture and Devonshire roads
