Seven major road corridors in Sydney’s rapidly growing south-west have been identified for future upgrades under a $65 million joint planning initiative by the Australian and New South Wales governments.

The expanded South West Sydney Roads – Planning Project aims to ease traffic congestion, improve road safety, and support ongoing housing and job growth in Sydney’s Greater Macarthur and South West regions.

Business cases and planning investigations will be prepared for the seven priority corridors, which together comprise some 76.5 km of roads that carry more than 100,000 vehicles daily.

These will provide a road map of staged delivery of improvements including widening key routes, adding new entry and exits points, new intersections and town centre bypasses.

The focus is on busting road congestion, improving safety and supporting ongoing housing and job growth as the South West and Greater Macarthur communities grow.

These routes are vital links between residential communities, employment hubs and freight routes. It is essential to plan for the infrastructure the region needs now, and to plan for the next round of major road infrastructure projects. Planning for jointly funded upgrades have been identified for four key corridors, including:

Hume Motorway – Narellan Road to Picton Road: A strategic options plan and access strategy will examine improvements to entry and exit points and traffic flow along this critical freight route, which carries more than 52,000 vehicles daily.

Cowpasture Road – M7 Motorway to Camden Valley Way: Widening from four to six lanes is proposed to support housing development around Bradfield City and the Western Sydney Airport precinct. The corridor currently sees more than 41,000 vehicles each day.

Camden Valley Way – M5 Motorway to Narellan Road: Also set for widening from four to six lanes, this route services suburbs that have grown significantly in recent years, adding over 20,000 residents and 5,000 jobs.

Menangle Road – Tindall Street, Campbelltown to Cummins Road, Menangle Park: Widening is planned to boost capacity along what is seen as an increasingly important local corridor. 

Additionally, three more corridors will now be investigated and plans developed as part of the $65 million program:

Campbelltown Road – between the Hume Highway and Brooks Road – proposed to expand from two to four lanes to improve safety and reduce congestion for the 34,000 vehicles using it daily.

Appin town centre bypass – to divert traffic away from the historic village and prepare for future demand.

Jersey Road – from Oran Park to Bradfield – subject to a planning study to support better public transport connections and road access between two of the region’s fastest-growing centres. Oran Park is forecast to create more than 2,500 jobs by 2026.

This consolidated program of planning for South West Sydney roads sits alongside a broader pipeline of committed infrastructure investments across Western Sydney, including:

• More than $2 billion for the toll-free M12 Motorway linking the M7 Motorway to the new Western Sydney Airport.
• $1 billion (Australian and NSW Government funding) to upgrade Fifteenth Avenue, including a six-kilometre section between Cowpasture and Devonshire roads.
• $380 million (Australian and NSW Government funding) to upgrade the M5 westbound between Moorebank Avenue and the Hume Highway.
• $800 million for the upgrade of the priority section of Elizabeth Drive upgrade to improve safety and reduce congestion.

Quotes attributable to Federal Minister for Infrastructure, Transport, Regional Development and Local Government Catherine King: 

“The Albanese Government is investing over $19 billion in Western Sydney, on a new airport, and roads and rail to keep people moving. 

“This investment in future planning for Sydney’s road network keeps our infrastructure pipeline moving, developing future opportunities to keep locals working on sites close to home on projects that will keep Western Sydney moving.”

Quotes attributable to NSW Minister for Roads Jenny Aitchison: 

“This planning work is about making sure the road network keeps pace with the needs of communities across south west Sydney, both now and well into the future.

“We’re working closely with the NSW Government to ensure strategic transport corridors are planned properly so they can support the region’s growth and help keep people and freight moving efficiently.

“Sydney’s south west is changing fast – expanding communities, new industries and a new airport are reshaping the region, and our planning needs to reflect that. This work ensures we’re preparing the road network for the future, not just reacting to growth once it arrives.

“With the Western Sydney Airport and Bradfield City on the horizon, we’re taking a coordinated approach to planning the infrastructure that will support how people live, move and work in this growing part of Sydney.”

Quotes attributable to Federal Member for Macarthur Mike Freelander: 

“As our community grows, it’s vital we keep planning for the future. I’m pleased to be working with the Albanese and Minns Governments on planning for future road upgrades on the busy Hume Highway and Menangle Road.
