WestConnex 3B is the Rozelle Interchange, a major underground motorway interchange that is the final stage of the WestConnex project. It connects the M4-M5 Link Tunnels to the City West Link, creates an underground bypass of Victoria Road between the Iron Cove and ANZAC Bridges, and links to the future Western Harbour Tunnel. The project is situated at the former Rozelle Rail Yards, will include new tunnels, and will also create approximately 10 hectares of new public green space.
