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.
