WestConnex is Australia’s largest road project and is part of an integrated transport plan to keep Sydney moving; easing congestion, creating jobs and connecting communities. WestConnex will provide a vital missing link in Sydney’s motorway network and support Sydney’s economic growth and urban revitalisation.

The Rozelle Interchange is a new underground motorway interchange which provides connectivity to the M4-M5 Link Tunnels and the City West Link, and underground bypass of Victoria Road between Iron Cove Bridge and Anzac Bridge. The Rozelle Interchange also provides a connection to the future Western Harbour Tunnel.

The interchange in Rozelle will be mostly underground and tunnelling will be conducted from the site of the old Rozelle Rail Yards. It will deliver new active transport options in Rozelle and transform the disused site into up to 10 hectares of open space.

A joint venture of John Holland and CPB (JHCPB) has been contracted to design and construct the Rozelle Interchange & Western Harbour Tunnel Enabling Works.
