Updates and announcements

Roads and Maritime Services has started planning for the progressive upgrade and widening of the Mulgoa Road / Castlereagh Road corridor between Glenmore Parkway, Glenmore Park and Andrews Road, Penrith.

We are seeking local knowledge of the area and early feedback from the community and stakeholders to assist us with planning and identifying the best option for this road corridor upgrade. View or download the August community update (PDF, 1.4MB) for further information.

Comments are invited until Friday 25 September 2015. You can provide your comments by:

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 about 2500 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 and employment in its immediate vicinity and contribute to associated travel demand. These include Penrith Panthers Entertainment Precinct, Penrith Station Precinct, Riverlink and Nepean River Precincts, Sportingbet Stadium, Penrith Lakes and the Bulky goods Precinct, as well as the new urban land releases at Glenmore Park and Thornton.

In late 2014 Roads and Maritime released a Preferred Option Report for the Jane Street and Mulgoa Road Infrastructure Upgrade. As this project forms the first part of the Mulgoa Road / Castlereagh Corridor Upgrade, planning and staging of these two projects will be coordinated.

Project benefits

The main benefits of the proposal include:

  • Managing congestion and delays along Mulgoa Road / Castlereagh Road during morning and afternoon peak periods
  • Reduced travel times and lower transport costs
  • Improved road safety for all users
  • Supporting residential and employment growth and providing reliable network performance to support economic growth and productivity by providing road capacity for predicted 2036 traffic volumes
  • Improving access for public transport
  • Improving freight efficiency
  • Providing safe and effective pedestrian and cycling infrastructure
  • Improving urban design and visual aspects of the road corridor.

What happens next?

Roads and Maritime is now carrying out investigation work and technical studies to inform a Preferred Option Report, which is scheduled to be published to the community later this year for community comment.
