Updates and announcements

In August and September 2015, Roads and Maritime consulted with the community and stakeholders to seek local knowledge of the area and early feedback to assist with planning and identifying the best option for the Mulgoa Road / Castlereagh Road corridor between Glenmore Parkway, Glenmore Park and Andrews Road, Penrith.

We would like to thank the community for their feedback during the consultation period and for further information on this project, you can view or download the August community update (PDF, 1.4MB).

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, Nepean River, Penrith Stadium, Penrith Lakes and the Penrith Homemaker Centre, as well as the new urban land releases at Glenmore Park and Thornton.

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 will be published and available soon for the community to comment.
