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
  • extended the M4 in twin underground tunnels from Homebush to Haberfield
  • created smoother road surfaces and new access points to the New M4 between Parramatta and Homebush
  • lengthened the on and off-ramps at the King Georges Road M5 interchange, providing more capacity and reducing congestion for motorists.

WestConnex will:

  • 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 CBD; and
  • provide connections to the future Western Harbour Tunnel, BeachesLink, F6 extension and major international gateways at Sydney Airport and Port Botany.
