The Australian and NSW Governments are planning to widen and upgrade Mulgoa Road / Castlereagh Road to support current and future traffic demands and expected growth in the area.
Transport for NSW is upgrading 6.5 kilometres of the Mulgoa Road / Castlereagh Road corridor between Glenmore Parkway, Glenmore Park and Andrews Road, Penrith. Mulgoa Road is a main access route from Penrith to the M4 Motorway.
The corridor connects the Penrith community, including its central business district, with other parts of greater Sydney.
The upgraded road would improve road safety, reduce congestion and improve travel times.
Subject to funding, the corridor upgrade would be developed and delivered in stages over the next 20 years.
