Updates and announcements

Field investigation work

Roads and Maritime Services will be carrying out field investigations to locate utilities for the Jane Street and Mulgoa Road Infrastructure Upgrade.

These investigations include minor excavation and will take place at multiple locations within the project boundary.

The work will take up to 25 shifts to complete between 7am and 6pm from Monday 1 May to Monday 5 June 2017, weather permitting. In order to minimise impacts on motorists, some night work will be carried out between 8pm and 5am when traffic volumes are lower.

For more information, please see our project notification letter.

Consultation now closed

Roads and Maritime Services sought comments from the community and stakeholders on the concept design and Review of Environmental Factors (REF) for the Jane Street and Mulgoa Road Infrastructure Upgrade in November and December 2016. We would like to thank everyone who considered the proposal and provided feedback.

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

The latest animation video and community update newsletter provides more information on the project and the Review of Environmental Factors (PDF, 12.2Mb) is available to download.

Project snapshot

  • Project value: $70 million
  • Funding: Australian and NSW governments

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.

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 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 is considering 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 is being prepared for publication in early 2017.

Other projects in the area

Mulgoa Road / Castlereagh Road Corridor Upgrade

The NSW Government are 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.
