Jane Street and Mulgoa Road Infrastructure upgrade

The Australian and NSW governments are jointly funding the $70 million Jane Street and Mulgoa Road Infrastructure upgrade. The vital upgrade will connect road users to the Penrith CBD and ease congestion at these intersections.

Updates and announcements

Field investigation work

Roads and Maritime Services has extended the investigation period for an extra two months due to the complexity of the work.

We will carry out surveys, utilities investigation and soil sampling work to further refine the design of the Jane Street and Mulgoa Road infrastructure upgrade.

The investigations include minor excavation and will take place at multiple locations within the project boundary. We have included a map to show where we will be working.

The work will take place at night between Tuesday 2 January and Friday 30 March 2018, weather permitting. To minimise the impact on road users, work will be carried out between 8pm and 5am when traffic volumes are lower. Some off road work like soil sampling will occur in the day between 7am and 6pm.

Submissions Report for the Review of Environmental Factors and concept design now available

In November and December 2016, Roads and Maritime Services invited comments from the community and stakeholders on the Review of Environmental Factors and concept design.

We received 22 submissions, all generally in favour of the proposal. We have summarised the feedback and our responses in a Submissions Report (PDF, 3.62Mb).

After considering all responses including the project aims and design requirements, we have decided to proceed with the proposal. We thank everyone for considering the proposal and for their feedback and have responded in the report directly to each of the questions or concerns raised.

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?

We have awarded the design contract to SMEC. Roads and Maritime is planning to invite tender for construction in 2018. We will provide an update before work starts and will continue to provide information as the project progresses.
