Sydney West

Roads and Maritime Services is working to plan and build the new and upgraded major arterial roads that will ensure western Sydney is ready for the population growth ahead.

Western Sydney covers almost 9,000 square kilometres and is home to about two million people. With Sydney's population predicted to increase by around 1.6 million people by 2034, western Sydney faces unprecedented growth with one million extra people predicted to live in the region by 2031.

Right now, more than 845,000 journeys to work start and end in western Sydney and 64 per cent of those are by car.

That's why it's vital to ensure our road infrastructure supports transport connections, moves freight, eases congestion, provides more reliable travel times and makes roads safer.

The Western Sydney Infrastructure Plan

The Australian and NSW governments are funding the Western Sydney Infrastructure Plan, a 10 year, $3.6 billion road investment program. This will deliver new and upgraded roads to support integrated transport in the region and capitalise on the economic benefits from developing the Western Sydney Airport at Badgerys Creek.

The Australian and NSW governments are improving the road network before Western Sydney Airport opens at Badgerys Creek in 2026, creating thousands of direct and indirect jobs for the region.

As part of the Plan, the Australian Government is also investing $200 million in a Local Roads Package, enabling western Sydney councils to deliver improved road connections to support the Western Sydney Infrastructure Plan.
