WestConnex projects

M4 Widening

Stretching 7.5km between Parramatta and Homebush and increased from six to eight lanes, the New M4 is an even faster way to bypass 28 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.

M4 East

The M4 East project will extend the M4 Motorway in tunnels between Homebush and Haberfield via Concord, and includes provision for the future connection to M4–M5 Link. The project is about 6.5km long - with 5.5km of the motorway underground - making it the first underground section of WestConnex. It will connect to the widened M4 and extend it via twin motorway tunnels from Homebush to Haberfield with three lanes in each direction. The M4 East will alleviate the frustrating delays and gridlock that motorists face daily when they come off the M4 and hit a standstill on Parramatta Road.

King Georges Road interchange upgrade

This included an upgrade of the King Georges Road interchange between the M5 West Motorway and the M5 East Motorway at Beverly Hills, in preparation for the New M5 project. Work was fast-tracked, and the upgraded interchange opened to traffic in December 2016

New M5

Duplicating the M5 East from King Georges Road Interchange Upgrade at Beverly Hills with twin motorway tunnels from Kingsgrove to a new interchange at St Peters. The St Peters Interchange includes connections to the Sydney Gateway and M4–M5 Link. The New M5 tunnels also include underground connection points for the M4-M5 Link and the proposed Southern Connector. The New M5 will provide twin underground motorway tunnels, nine kilometres long, from Kingsgrove to a new St Peters Interchange at the site of the old Alexandria landfill facility. The new interchange at St Peters will provide motorists with connections to Alexandria and Mascot.

M4-M5 Link

Tunnels connecting to the M4 East at Haberfield and New M5 at St Peters via Rozelle and Camperdown. Includes an interchange at Rozelle with provision for a future connection to the Western Harbour Tunnel and BeachesLink. The project also includes an underground tunnel from the Rozelle Interchange to Iron Cove Bridge. Construction of the M4–M5 Link will not start until 2019, following extensive community feedback and consultation and pending planning approval. During the coming months we will be consulting with the local community and key stakeholders to develop a reference design and we plan to release this in late 2016.

M4-M5 Link Rozelle Interchange

Tunnels connecting the mainline tunnels with the other sections of the road network via Rozelle

The M4-M5 Link is being delivered in two stages:

Stage one - construction of the mainline tunnels between the New M4 at Haberfield and the New M5 at St Peters and stub tunnels to the Rozelle interchange. This stage is being managed by Sydney Motorway Corporation.  
Stage two - construction of the Rozelle Interchange and Iron Cove Link. A contractor is expected to be appointed by the end of 2018. This stage is being managed by Roads and Maritime Services.
