WestConnex is another component of the NSW Government’s integrated transport plan. The NSW Government advises that WestConnex will:

  • Widen the M4 between Parramatta and Homebush and extend it in underground tunnels between Homebush and Haberfield.
  • Double road capacity along the M5 East corridor with the New M5 underground tunnels running between St Peters and Kingsgrove.

  • Join these underground routes together via the M4–M5 Link tunnel to form a seamless motorway without traffic lights.

  • Provide a western bypass of the Sydney central business district (CBD).

  • Provide connections to the Western Harbour Tunnel and BeachesLink.

  • Provide a connection to Sydney Airport and Port Botany via Sydney Gateway.
