Benefits

We are building a growing city.  WestConnex is part of an integrated transport plan to keep Sydney moving –  easing congestion, creating jobs and connecting communities. The new motorway will provide crucial support for Sydney’s long-term economic and population growth.

 

WestConnex has:

  • Widened the M4 between Parramatta and Homebush, creating an even faster way to bypass 28 sets of traffic lights on Parramatta Road
  • Created smoother road surfaces and new access points to the new M4 between Parramatta and Homebush

 

WestConnex will:

  • Extend the M4 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.
