Western Sydney motorists are set to benefit from a major road transformation with the official opening of the $280 million Prospect Highway upgrade.

The Albanese and Minns Labor Governments have jointly funded and delivered this significant infrastructure upgrade, which has widened the previously congested stretch of road into a modern, multi-lane highway.

What the Upgrade Delivers

The Prospect Highway, a key connector in Western Sydney's road network, now features:

  • Six lanes between St Martins Crescent and Blacktown Road
  • Four lanes between Blacktown Road and Reservoir Road
  • Two new bridges over the M4 Motorway and Great Western Highway
  • A new link road between Great Western Highway and Prospect Highway
  • Signalised intersection upgrades for safer, more efficient flow
  • Kerb-side bus lanes in each direction between Lancelot Street and north of St Martins Crescent
  • A new kiss-and-ride facility at Shelley Public School
  • A pedestrian underpass
  • 3.7km of upgraded shared user path for pedestrians and cyclists

Big Wins for Motorists and the Community

Before the upgrade, more than 35,000 vehicles and 5,000 trucks used the highway daily, often experiencing travel delays of up to 20 minutes. With the new lanes and modern infrastructure, that time has been cut down to approximately 5 minutes.

The road's speed limit has also increased from 60 km/h to 70 km/h between Reservoir Road and St Martins Crescent, thanks to improved road safety features.

Supporting Western Sydney Growth

With Blacktown forecasted to grow to more than 563,000 residents by 2041, the Prospect Highway upgrade ensures the region can handle future demand while improving the everyday lives of current residents.

Federal Infrastructure Minister Catherine King said: "Thanks to these major improvements, about 35,000 motorists and 5,000 heavy vehicles who use this road daily will benefit from reduced congestion, faster travel times and safer journeys."

Premier Chris Minns added: "Prospect Highway is a vital north-south road in Western Sydney and for too long, it was an outdated two-lane traffic bottleneck. This upgrade gets drivers moving again on a safer road."

Economic and Local Benefits

Beyond easing traffic congestion, the project supported around 2,000 jobs and saw strong participation from Aboriginal businesses and workers, with 101 Aboriginal people contributing to construction.

The upgrade is also expected to boost the efficiency of local freight movement, helping business and logistics sectors thrive in one of Australia’s fastest-growing corridors.

A Safer, Smoother Journey Ahead

With its improved intersections, new bridges, and dedicated bus and pedestrian facilities, the new Prospect Highway is more than just a road upgrade. It represents a long-overdue investment in Western Sydney's transport future, delivering a safer, faster, and more connected route for the region's residents and businesses.
