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

Night and day work for investigations – Mulgoa Road from 2 July to 18 August 2018

Roads and Maritime Services will carry out work to locate underground services and structures as well as further geotechnical investigations at various locations along Mulgoa Road and some surrounding local roads, weather permitting. These investigations will help to inform the design and environmental assessment of the upgrade to Mulgoa Road at Regentville and Jamisontown.

These investigations will require 21 shifts to be completed from Monday 2 July until Saturday 18 August 2018, weather permitting.

Day work is expected to occur on weekdays during standard hours between 7am and 6pm and on Saturdays between 8am and 1pm. Night work is expected to occur on some weekdays and weekend nights, including some Saturday and Sunday nights, between 8pm and 6am.

Project background

Roads and Maritime are upgrading 6.5 kilometres of the Mulgoa Road / Castlereagh Road corridor between Glenmore Parkway, Glenmore Park and Andrews Road, Penrith which is a State arterial road and a main access route from Penrith to the M4 Motorway.

Mulgoa Road / Castlereagh Road corridor connects Penrith’s Local Government Area, including its Central Business District, with other parts of greater Sydney. The improved road will reduce the congestion and traffic delays currently experienced whilst improving the road safety.

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.

The Mulgoa Road / Castlereagh Road corridor has been divided into sections for planning and delivery.

  • Jane Street, Penrith – Union Road to Museum Drive including Railway Bridge (construction begins 2019)
  • Mulgoa Road, Jamisontown – Jeanette Street to Blaikie Road including M4 Motorway (consruction begins 2020)
  • Mulgoa Road, Glenmore Park – Glenmore Parkway to Jeanette Street (pre-design, short term upgrade)
  • Castlereagh Road, Penrith – Museum Drive to Coreen Avenue (pre-design, short-term upgrade)
  • Castlereagh Road, Penrith Lakes – Lugard Street to north of Andrews Road (pre-design, short-term upgrade)
  • Mulgoa Road, Penrith – Blaikie Road to Union Road (pre-design, medium-term upgrade)
  • Castlereagh Road, North Penrith – Coreen Avenue to Lugard Street (pre-design, long-term upgrade)

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.

Community consultation report

Community consultation report now available

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. The Consultation Report summarising and responding to feedback received during the consultation period is now available.

As a result of feedback received, Roads and Maritime has made the following adjustments to the displayed option in April and May 2017:

  • change in design south of Glenmore Parkway to use the existing road preservation and remove the impact to property (Appendix G – Sketch A)
  • introduction of a median on Glenbrook Street to prevent rear-end incidents while accessing Peter Court (Appendix G– Sketch B)
  • further investigation is required for the alignment along Hatchinson Crescent, Huron Place and Peter Court (Appendix G – Sketch B)
  • further investigation is required for the alignment outside the Grey Gums Hotel property to allow for access from Mulgoa Road into the property (Appendix G Sketch B)
  • minor changes to median and verges to work with the proposed development by Panthers (Appendix G – Sketch C)
  • further investigation is required for the Union Road intersection and if required, changes will be considered in consultation with Penrith City Council.

For information about the project see our animation video, and the Preferred Option Report

What happens next?

The Mulgoa Road / Castlereagh Road corridor between Glenmore Parkway, Glenmore Park and Andrews Road, Penrith will now be preserved for the future upgrade. 

The Australian and NSW Governments are fast-tracking work on the first stage of corridor between Jeanette Street, Regentville and Blaikie Road, Jamisontown. 

A concept design for this part of the upgrade is currently being developed with a Review of Environmental Factors to be displayed for comment in mid-2018.
