Project background

The Jane Street / Mulgoa Road / Castlereagh Road and the High Street / Mulgoa Road intersections play a vital role in connecting road users to the Penrith CBD, Blue Mountains and surrounding suburbs. These intersections currently experience congestion during the morning and afternoon peak times.

Additionally, as part of the NSW Government’s Plan for Growing Sydney, Penrith will continue to grow as a regional city centre and accommodate future residential and employment growth. Without any improvement to cater for this growth, future traffic congestion at these intersections will worsen, resulting in further delays for road users.

The Jane Street and Mulgoa Road Infrastructure Upgrade would ease this congestion and provide increased capacity to cater for future transport growth.


The Jane Street and Mulgoa Road Infrastructure Upgrade would:

  • Reduce congestion and delays at the Jane Street / Castlereagh Road and High Street / Mulgoa Road intersections during morning and afternoon peak times
  • Deliver infrastructure that provides effective network performance
  • Improve access to public transport
  • Provide safe and effective pedestrian and cycling infrastructure
  • Support economic growth
  • Allow for upgrades of other sections of Mulgoa Road in the future

Key features

The key features of the Jane Street and Mulgoa Road Infrastructure Project include:

  • An additional lane both north and south bound on Mulgoa Road / Castlereagh Road between Union Road and to the south of Museum Drive
  • A longer left turn lane along Mulgoa Road for vehicles turning westbound onto the Great Western Highway
  • An upgrade of the Mulgoa Road and High Street intersection to provide increased capacity
  • An upgrade of the T-intersection of Jane Street with Castlereagh Road/Mulgoa Road to provide increased capacity
  • Widening the existing rail underpass to allow three lanes in each direction on Castlereagh Road and left turn into Jane Street
  • Bus priority at the Jane Street and High Street intersections

What happens next?

Roads and Maritime will consider all feedback received during the display of the concept design and Review of Environmental Factors. A Submissions Report summarising the feedback received and the responses from Roads and Maritime will be prepared and published in early 2017.

Mulgoa Road / Castlereagh Road Corridor Upgrade

The Australian and NSW governments are planning for a potential future widening and upgrade of Mulgoa Road / Castlereagh Road to support current and future traffic demands and expected growth in the area.

Roads and Maritime is carrying out investigations and technical studies to inform a Preferred Option Report, which is scheduled to be published for comment shortly.
