WestConnex. A better M4.

The 7.5km stretch of the New M4 between Parramatta and Homebush has increased from six to eight lanes, creating an even faster way to bypass 28 sets of traffic lights on Parramatta Road and reduce travel times in the west.

The WestConnex M4 opens to motorists on 15 July 2017 and a distance-based toll will begin for the upgraded section a month later (meaning your tag will beep on and off). The M4 west of Parramatta remains free.

Work to extend the New M4 from Homebush to Haberfield in underground tunnels is well underway, opening in 2019 for faster trips bypassing Parramatta Road. By 2023, the M4 will link to a New M5, creating a western bypass of the city for faster, safer and more reliable trips.

For faster journeys, more lanes and less time on the road, please see the following information about the WestConnex New M4:
