Once complete and pending the construction of the proposed Beaches Link, there will be a continuous connection from WestConnex at Rozelle to Sydney’s Northern Beaches.
Main works for Stage One includes construction of approximately 1.7 kilometres of twin three-lane tunnels between Rozelle and Birchgrove.
