M4-M5 Link Environmental Impact Statement and Modification

Sydney’s population is set to grow by more than one million people in the next 10 years, with our already congested road network expected to cater for an estimated 21 million trips per day by 2036.

The NSW Government is spending a record $41.5 billion on road and public transport projects over the next four years to deliver an integrated transport solution for greater Sydney.

WestConnex is part of the Government’s vision for supporting Sydney’s growing population. Upon completion, it will provide safer, faster and more reliable travel, and make it easier for businesses and communities to connect.  

The M4-M5 Link is a critical part of WestConnex, connecting the New M4 (incorporating the M4 East and M4 Widening projects) with the New M5, and allowing the full benefits of WestConnex to be realised.

About the EIS

The M4-M5 Link Environmental Impact Statement (EIS) was on public exhibition from 18 August to 16 October 2017. During this 60-day consultation period, stakeholders were encouraged to review the EIS and make a formal submission about the project to be considered by the Department of Planning and Environment as part of its assessment of the project.

The M4-M5 Link project team held five information sessions to complement the release of the M4-M5 Link EIS. During these sessions, stakeholders and community members were given the opportunity to discuss the EIS with technical specialists and learn about the submissions process. These sessions were attended by more than 250 members of the inner west community. 

The Community Guide to the M4-M5 Link Environmental Impact Statement addresses the key areas of interest identified through community feedback over the past 12 months as part of the project’s community engagement program.  

It includes a project summary, an overview of potential impacts, and a reference to the relevant sections of the EIS to help you find more detailed information. It does not replace the EIS.

A Modification report describing these changes is now on exhibition and the community is invited to comment until 26 September 2018.
