Mulgoa Road / Castlereagh Road Corridor upgrade

The NSW Government is planning to widen and upgrade 6.5 kilometres of Mulgoa Road / Castlereagh Road between Glenmore Parkway, Glenmore Park and Andrews Road, Penrith to support current and future traffic demands and expected growth in the area. This includes the Australian and NSW governments' commitment of $100 million to fast-track the first stage of the upgrade between Jeanette Street, Regentville and Blaikie Road, Jamisontown.

Updates and announcements

Consultation now closed

Roads and Maritime Services invited comments from the community and stakeholders on the preferred option for the Mulgoa Road / Castlereagh Road Corridor upgrade in April and May 2017. We would like to thank everyone who considered the proposal and provided feedback.

A consultation report summarising and responding to feedback received during the consultation period is now being prepared.

For more information on the preferred option, see our latest animation video, community update newsletter (PDF, 2.09Mb) and the Preferred Option Report (PDF, 5.24Mb).

Field investigations for the first stage of the proposed Mulgoa Road / Castlereagh Road upgrade

Roads and Maritime Services will carry out investigations and survey work in several locations along Mulgoa Road in September and October, 2017. These investigations will help inform the design and environmental assessment for the first stage of the Mulgoa Road / Castlereagh Road corridor upgrade.

The work involves installation of noise monitoring devices at some locations, ground surveying and visual inspections. For further information, please view or download the August 2017 notification letter (PDF, 282Kb).

Project snapshot

  • Project value: $100 million (for stage one only)
  • Funding: Australian and NSW governments

Project background

The Mulgoa Road / Castlereagh Road corridor is a State arterial road and one of two main access routes from Penrith to the M4 Motorway. Mulgoa Road and The Northern Road connect Penrith’s Local Government Area, including its Central Business District, with other parts of greater Sydney.

The corridor carries significant traffic volumes of up to 3800 vehicles per hour during morning and afternoon peak periods.

There are a number of key developments served by Mulgoa Road / Castlereagh Road that have increased population, employment and traffic congestion in the area. These include Penrith Panthers Entertainment precinct, Penrith Station, Riverlink precinct, Penrith Stadium, Penrith Lakes and the Penrith Homemaker Centre, as well as the new urban land releases at Glenmore Park and Thornton.

Stage 1 Jeanette Street to Blaikie Road

In July 2016, the Australian and NSW governments announced a funding commitment of $100 million to widen Mulgoa Road between Jeanette Street, Regentville and Blaikie Road, Jamisontown. As part of the Stage 1 corridor upgrade, Mulgoa Road would be widened from two to three lanes in each direction. Comments received from the preferred option consultation will inform the concept design and environmental assessment for Stage 1 which will be displayed for community consultation.  Further planning and development for Stages 2 to 6 are dependent on additional funding.

Project benefits

The preferred option would:

  • improve road capacity to cater to population and employment growth
  • manage congestion and delays along Mulgoa Road / Castlereagh Road during peak periods
  • reduce travel times and transport costs
  • improve road safety for all users
  • improve the movement of goods and trucks
  • improve access to public transport
  • provide safe and effective pedestrian and cycling infrastructure
  • improve urban design and visual aspects of the road corridor.

Key features

The preferred option includes:

  • three lanes in each direction
  • upgraded intersections – including traffic light intersections at Andrews Road, Coreen Avenue and Glenmore Parkway
  • bus priority at intersections
  • a separated path for pedestrians and cyclists on the eastern side
  • a footpath on the western side
  • landscaping along the corridor.

What happens next?

Roads and Maritime is considering all feedback received during the display of the preferred option. A consultation report summarising the feedback received and the responses from Roads and Maritime is being prepared for release in the second half of 2017.

Roads and Maritime will finalise the corridor studies for the upgrade and once complete, the concept design and environmental assessment for Stage 1 Jeanette Street to Blaikie Road will be prepared. Further planning and development for Stages 2 to 6 are dependent on additional funding.
