About
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
- lengthened the on and off-ramps at the King Georges Road M5 interchange, providing more capacity and reducing congestion for motorists.
- extend the M4 in twin underground tunnels from Homebush to 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 CBD; and
- provide connections to the future Western Harbour Tunnel, BeachesLink, F6 extension and major international gateways at Sydney Airport and Port Botany.
