  • New M4, between Church Street Parramatta and Homebush.

WestConnex is extending the M4 to Haberfield, as well as increasing capacity along the M5 East corridor, and providing a link tunnel to join the M4 and M5.

New M4

The section of the M4 Motorway between Parramatta and Homebush is known as
the New M4.

This 7.5 kilometre section of the M4 Motorway was widened from 3 to 4 lanes in each direction between Parramatta and Homebush, as well as new and upgraded on and off ramps, as part of the WestConnex project.

The New M4 provides motorists with faster, safer and more reliable trips, bypassing 28 sets of traffic lights on Parramatta Road and reducing travel times in the west.

The Widened New M4 officially opened on Sunday, 16 July 2017.

Work to extend the M4 underground from Homebush to Haberfield is now complete, opening in July 2019 for faster trips bypassing Parramatta Road.

The M4 Motorway and tolls

The M4 west of Parramatta remains free and represents more than 80% of the M4 Motorway.

The New M4 has a distance-based toll between Parramatta and Haberfield.
