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.

Tolls will only be charged once new or significantly upgraded sections of road are opened to motorists.

For each WestConnex project, a series of documents including details of the measures to appropriately manage and reduce the impact of the project on local communities. These include: 

  • The Environmental Impact Statement (EIS) – the EIS explores the potential environmental impact and outlines measures to manage and reduce this impact based on best practice and expert advice. 
  • The Submissions Report – this responds to all feedback received on the EIS during exhibition. It provides additional mitigation measures needed in response to new information, additional assessment or community feedback. 
  • The Conditions of Approval – in approving each project, the NSW Minister for Planning issues a range of conditions that must be adhered to during and after construction, to ensure impact of the project is mitigated. 
  • The Construction Environmental Management Plan and sub plans – before we start major work, these are prepared to provide a detailed approach to the management of environmental issues. The Department of Planning and Environment must approve these before major construction work can start. They build on the mitigation and management measures established in the EIS, the Submissions Report and Conditions of Approval.

We always notify local communities before we start a new section of work and before we do any out-of-hours work. 

WestConnex will have a distance-based tolling system, similar to the existing M7 Motorway. Motorists will pay only for the sections of the motorway they use and a maximum cap applies.

Tolls will be introduced as each section of WestConnex opens to traffic. The first tolls will start on the M4 in 2017, when the M4 Widening project is opened to traffic.

Cars will pay one third of the heavy truck toll, reflecting the greater wear and tear trucks have on the motorway (an approach that is consistent with other Sydney motorways).
