Prospect Highway upgrade

The NSW Government is planning to upgrade 3.6 kilometres of the Prospect Highway between Reservoir Road at Prospect and St Martins Crescent at Blacktown. This would reduce congestion and to help meet future demands on this corridor.

Project background

The NSW Government has provided $9.6 million to plan the Prospect Highway upgrade between Reservoir Road at Prospect and St Martins Crescent at Blacktown.

The project would upgrade this section of the Highway to a four lane divided road from an undivided two lane road, to cater for forecast transport growth along this corridor.

The community has provided feedback throughout the project’s planning including on the concept design, Review of Environmental Factors and detailed design.

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 the 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 the M4 Motorway and the Great Western Highway
  • A new two way link road between the Great Western Highway and the Prospect Highway, with traffic lights at each end of the new road
  • New traffic lights at:
    • Stoddart Road
    • M4 Motorway eastbound entry and exit ramps
    • Reservoir Road

  • Changing access arrangements at:
    • Tudor Avenue
    • Roger Place
    • Vesuvius Street
    • Ponds Road

  • Upgrading the existing shared path on the western side of the Prospect Highway between the M4 Motorway and Blacktown Road
  • Installing kerbside bus lanes between Lancelot Street and north of St Martins Crescent.

An addendum Review of Environmental Factors was needed to assess extra work that was identified during the detailed design phase of this project.

The addendum Review of Environmental Factors is now finalised and features:

  • Four extra noise wall locations along sections of the Prospect Highway
  • Acoustic architectural treatments for eligible dwellings
  • A kiss-and-ride facility for Shelly Public School within the school grounds
  • Modification of the intersection at Hadrian Avenue and Keyworth Drive to provide a roundabout and the associated utilities relocation
  • A change to the posted speed limit on Prospect Highway between Reservoir Road and Blacktown Road, from 60km/h to 70km/h
  • 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.

For more information, please view the finalised addendum Review of Environmental Factors report.

What happens next?

Planning for this project is now complete. We will inform the community when the project is ready to move into the construction stage.
