The New M4

Stretching 7.5km between Parramatta and Homebush and increased from six to eight lanes, the New M4 is an even faster way to bypass 22 sets of traffic lights on Parramatta Road and reduce travel times in the west. The New M4 has also been upgraded to have smoother road surfaces and, for the first time, motorists can now access the New M4 heading towards the city from the new Hill Road on-ramp, directly from Sydney Olympic Park.

A distance-based toll applies for the upgraded section. The M4 west of Parramatta remains free. 

Work to extend the New M4 from Homebush to Haberfield in underground tunnels (New M4 Tunnels) is complete. The New M4 Tunnels opened July 2019. By 2023, the M4 will link to a New M5, creating a western bypass of the city for faster, safer and more reliable trips. Take a virtual journey through the New M4 Tunnels now.
