The Western Harbour Tunnel proposal involves the construction of a motorway crossing underneath Sydney Harbour, connecting WestConnex with the Warringah Freeway.
The business case is for removing six level crossings on the inner Armadale Line. The project aims to improve safety and reduce congestion at the level crossings, as well as improving station precincts and public open space.
The business case is for a 27-kilometre four-lane grade-separated dual carriageway road at the outer edge of Bunbury. It would connect the Bussell Highway, north of Bunbury, to the Forrest Highway in the south.
This business case proposes an alternative freight access route to the Port of Albany. The project would involve a ring road around the urban areas of Albany, which aims to improve freight efficiency and help separate freight, local and tourist traffic within Albany.
The Rockhampton Ring Road proposal is part of the Bruce Highway Upgrade Program. It is designed to provide an alternative to the existing section of the Bruce Highway through Rockhampton.
The business case is to extend the Armadale Line approximately eight kilometres south to Byford. This is to support and provide public transport access to the high-growth suburb of Byford.
The business case was accepted for Infrastructure Australia's evaluation on 14 July 2020.
