M4-M5 Link Environmental Impact Statement

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 Environmental Impact Statement (EIS) describes the main features of the proposed M4-M5 Link project, as well as potential environmental and social impacts that may occur during construction and operation.

The EIS has been prepared prior to the appointment of design and construction contractors. This means the approach presented in the EIS is indicative only and subject to detailed design and construction planning to be undertaken by the successful contractor.  

We have used a conservative approach, with the potential impacts based on worst-case scenarios. The final design presented by the contractor would need to be consistent with any environmental management measures and conditions of approval for the project. Issues raised during the EIS public consultation period (Friday 18 August – Monday 16 October 2017) will also be considered during the detailed design process.

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. 

Have your say

You are invited to make a submission on the M4-M5 Link Environmental Impact Statement, which is on exhibition from 18 August to 16 October.

Roads and Maritime will consider all submissions received and provide a Preferred Infrastructure Report in response to the issues raised. The report will be submitted to the NSW Department of Planning and Environment and helps to inform the Minister for Planning’s decision on the project.

If the project is approved by the Minister for Planning, it will be constructed and operated in accordance with the mitigation measures described in the EIS, the Preferred Infrastructure Report and the Minister’s Conditions of Approval. The plans proposed in the EIS may evolve depending on several factors including community feedback, and the construction methodologies developed by the contractors once appointed.
