Project background

Roads and Maritime Services is planning to upgrade Prospect Highway between Reservoir Road, Prospect and St Martins Crescent, Blacktown.

Prospect Highway is a major roadway through western Sydney which connects motorists with the M4 Motorway, the Great Western Highway, Old Windsor Road and the M2 Motorway. Around 35,000 vehicles currently use the Prospect Highway each day, including 5000 heavy vehicles.

Prospect Highway between Reservoir Road, Prospect and St Martins Crescent, Blacktown is currently an undivided two lane road (one lane in each direction) which causes congestion and delays for motorists.

The upgrade will provide a 3.6 kilometre four lane divided road and will cater for forecast transport growth along this corridor.

Project benefits

Benefits of the upgrade include:

  • Improving safety and access for through and local traffic
  • Improving safety for cyclists and pedestrians
  • Improving travel times and reducing congestion on Prospect Highway between Blacktown and the M4 Motorway.

Key features

The key features of the Prospect Highway upgrade include:

  • Upgrading to a four lane divided road from an undivided two lane road
  • Duplicating the bridges over M4 Motorway and Great Western Highway
  • A new two way link road between Great Western Highway and Prospect Highway, with traffic lights at each end of the new road
  • New traffic lights at:
    • Stoddart Road

  • Providing acoustic architectural treatments for eligible dwellings
  • Providing a kiss-and-ride facility for Shelly Public School within the school grounds
  • Modifying the intersection at Hadrian Avenue and Keyworth Drive to provide a roundabout and the associated utilities relocation
  • Changing the posted speed limit on Prospect Highway between Reservoir Road and Blacktown Road, from 60km/h to 70km/h
  • Providing residential property adjustment work to improve entry and exit to properties to and from the Prospect Highway
  • Powerline relocation and associated clearing of trees within private properties along a section of the project between Bungarribee Road/ Leabons Lane and Blacktown Road, Seven Hills.

Community engagement

The Review of Environmental Factors for the Prospect Highway Upgrade was displayed for community comment between 2 June 2014 and 30 June 2014 at Blacktown City Council and Max Webber Library, Blacktown.

Roads and Maritime also hosted two community information sessions in June 2014 at Shelley Public School, Blacktown. Roads and Maritime would like to thank everyone who took the time to review the documents and provide feedback.

We received 52 submissions and overall there was general support for the upgrade. Roads and Maritime has considered the community’s feedback, prepared a Submissions Report in response to the feedback and obtained planning approval for the project. View or download the REF and Submissions Report.

What happens next?

Planning for this project is now complete and the project is moving into construction. A construction contract is expected in be awarded in the second half of 2019.

You may notice some investigations and minor works taking place along the alignment in the lead up to construction. We will continue to work with individual property owners and keep the community informed on the progress of the project.
