Project Timeline

M4 East

(Homebush to Haberfield)

Extending the M4 Motorway in tunnels between Homebush and Haberfield via Concord. Includes provision for the future connection to M4–M5 Link. 
The project is about 6.5km long (with 5.5km of the motorway in tunnel).
The M4 East is 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.

Environment and planning The M4 East received planning approval in February 2016 and work started in March 2016.

New and significantly improved sections of motorway delivered as part of WestConnex will be tolled as they progressively open to traffic between mid-2017 and 2023. Visit the tolls page for more information.

The first major part of WestConnex is the New M4 between Parramatta and Homebush which will provide motorists with better access ramps, new smoother road surfaces and extra lanes in each direction. This section represents 16 percent of the M4 Motorway meaning the more than 80 percent between Emu Plains and Parramatta will remain free.

There will be a one-month toll free period on the WestConnex New M4 after it opens to traffic in mid-2017 to help motorists adjust to the new and upgraded motorway

We are building a New M5 which will help almost halve average travel times on the current M5 East and double average travel speeds during peak times. We are also upgrading the M5 East and a toll will be introduced on this motorway to account for the massive improvements in travel time and reliability motorists will experience once the WestConnex New M5 is opened. 

To maintain access to Sydney Airport’s International Terminal, trips using Marsh Street ramps will remain toll free.

Some drivers will prefer to use the faster, wider WestConnex New M4 motorway. Others will prefer to use Parramatta Road. There will always be a choice.

Using the WestConnex New M4 will allow you to bypass 28 sets of traffic lights and a level crossing on Parramatta Road between Church Street Parramatta and Concord – meaning faster, safer and more reliable trips.

Roads and Maritime Services is working to ensure WestConnex is integrated into the local road network. Some changes have already been introduced on Parramatta Road to prepare for the opening of the WestConnex New M4.
