Project information

  • Project value: $105 million
  • Funding: Australian and NSW governments

The Castlereagh Road and Jane Street, and Mulgoa Road and High Street intersections are vital to connect road users to the Penrith CBD, Blue Mountains and surrounding suburbs. These intersections currently experience congestion during morning and afternoon peak times.

As part of the NSW Government Plan for Growing Sydney, Penrith will continue to develop 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 Mulgoa Road, Penrith - from Union Road to Museum Drive including Railway Bridge upgrade would ease this congestion and provide increased capacity to cater for future transport growth.

The Mulgoa Road, Penrith – from Union Road to Museum Drive including Railway Bridge upgrade would:

  • reduce congestion and delays at the Castlereagh Road / Jane Street 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.
  • 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 High Street
  • Upgrade of the Mulgoa Road and High Street intersection to provide increased capacity
  • Upgrade of the T-intersection of Jane Street with Castlereagh 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 High Street intersection.

Work started in December 2018 and the upgrade will open to traffic in mid 2021, weather permitting.

We will continue to provide information as the project progresses.

During our general excavation work, we have found asbestos contaminated material (ACM) along the High Street, Mulgoa Road and Castlereagh Road corridors.

If ACM is found near properties, property owners are notified before any removal takes place.

Roads and Maritime Services works with SafeWork NSW and the Environmental Protection Authority (EPA) in accordance with the relevant environmental and health obligations, and legislative requirements.

Should you have any questions about the safe removal of ACM, you can visit the Environmental Protection Authority’s website at or call 131 555.
