M6 - Stage 1

In October 2017, the NSW government announced it will proceed with the M6 Stage 1 (previously referred to as the F6 Extension - Stage 1). The project is a key element of the NSW Government’s transport vision for NSW, connecting Sydney’s south to the wider motorway network.

Project information

The M6 Stage 1 will deliver the missing link from Sydney’s south to the wider Sydney motorway network making journeys easier, faster and safer. It will remove more than 2,000 trucks a day from surface roads, and help return local streets to local communities.

Future Transport Strategy 2056 is the NSW Government’s 40 year vision for transport outcomes in NSW. The M6 Stage 1 is a key part of this strategy, supporting safe, efficient and reliable journeys for people and freight.

The M6 Stage 1 includes:

  • Twin four kilometre tunnels linking the New M5 Motorway at Arncliffe to President Avenue at Kogarah
  • Ramps between the main motorway tunnel and the surface intersection at President Avenue
  • Tunnel stubs for a future connection south to extend the M6
  • A new intersection at President Avenue including the widening and raising of President Avenue at this location
  • Provision of new shared cycle and pedestrian pathways connecting Bestic Street, Brighton-Le-Sands
  • Motorway support infrastructure including tunnel ventilation systems and the motorway control centre
  • New service utilities including a permanent power supply line
  • Minor adjustments to local roads in the project area.

The project is expected to cost between $2.2 and $2.6 billion, and open to traffic late 2024.

The M6 Stage 1 will:

  • Enable motorists to bypass up to 23 sets of traffic lights on the Princes Highway between St Peters and Kogarah
  • Be built underground to minimise disruption to the community and property impacts
  • Ease congestion, meaning less time in traffic and faster trips to the CBD and across Greater Sydney.
  • Reduce traffic on General Holmes Drive by 10,000 vehicles a day
  • Improve travel times and provide more direct access from southern Sydney to the wider Sydney motorway network
  • Improve pedestrian and cyclist safety through the new shared cycle and pedestrian pathways
  • Assist in the reduction of traffic congestion, particularly along Princes Highway through Arncliffe, Banksia and Rockdale, and The Grand Parade, Brighton-Le-Sands, and provide shorter travel times for road users
  • Improve the amenity of the foreshore precinct at Brighton-Le-Sands at The Grand Parade through a reduction in traffic and returning local streets to local communities
  • Reduce the number of trucks on surface roads by over 2,000 per day
  • Allow motorists to bypass Sydney Airport traffic
  • Contribute to a more accessible, more livable and productive Greater Sydney.

This project will deliver major travel time savings including:

M6 Stage 1Travel Time savings
Kogarah to Anzac Bridge 15 minutes
Kogarah to South Sydney 13 minutes
Kogarah to the City 8 minutes
Miranda to Macquarie Park 15 minutes
Taren Point to Mascot 12 minutes

Air quality in Sydney is good by national and international standards. According to data published by the World Health Organisation (WHO) who set global air quality guidelines, Sydney’s air quality is better than their guidelines and the air quality of other global cities such as Washington, Helsinki, London and Paris.

In February 2018, the NSW Government announced stronger measures on emissions from motorway tunnels. These measures include the EPA regulating the ventilation facilities of all current and future operating motorway tunnels to ensure they meet air quality limits.

As part of these measures additional checks are required before the EIS for the project can be approved by the Minister for Planning. They involve:

  • The Advisory Committee on Tunnel Air Quality (ACTAQ) coordinating a scientific review of the project’s air emissions from ventilation facilities
  • The NSW Chief Health Officer releasing a statement on the potential health impacts of emissions from tunnel ventilation facilities.

The M6 Stage 1 is the first tunnel project that was required to implement these measures. The ACTAQ review and Chief Health Officer statement are available to view on the Department of Planning and Environment’s website. The air quality considerations are addressed in the Environmental Impact Statement is now on exhibition.

Air quality modelling for the project showed that under expected traffic conditions for the project the predicted contribution of tunnel ventilation outlets to local air quality was negligible

Existing measures monitoring the air quality inside motorway tunnels remain in place. View the tunnel ventilation technology online video.

The M6 Stage 1 is undergoing a rigorous planning process and the Department of Planning and Environment has recently concluded the exhibition of the EIS for the project. The following documents support the planning process to date:

  • Secretary’s Environmental Assessment Requirements
    The DPE issued the Secretary’s Environmental Assessment Requirements for the project in December 2017. The SEARs established the issues that must be addressed and responded to in the Environmental Impact Statement.
  • State Significant Infrastructure Application
    Roads and Maritime submitted a State Significant Infrastructure Application with the Department of Planning, Industry and Environment (DPIE) early in the planning process to identify issues that must be addressed in the Environmental Impact Statement (EIS) State Significant Infrastructure Applications.
  • Scoping Report
    A Scoping Report was prepared by Roads and Maritime Services to support the State Significant Infrastructure Application. The Scoping Report is available to view or download or can also be viewed on the DPE Major Projects website.
  • Environmental Impact Statement
    The Environmental Impact Statement (EIS) examines all potential environmental and social impacts that may occur during the construction and operation of the project, and proposes mitigation measures to reduce these impacts. The EIS was publicly exhibited from 7 November to 14 December 2018, and is available to view or download on the DPE Major Projects website.
  • Submissions and Preferred Infrastructure Reports
    The Submissions Report and a Preferred Infrastructure Report (PIR) was prepared in response to submissions made by the community, councils and government agencies and are available to view or download on the DPE Major Projects website. The PIR assesses alternative design options that were an outcome of the EIS exhibition. Two changes to the design have been made based on feedback received:
  1. Traffic changes will include improved access arrangements on President Avenue
  2. The shared cycle and pedestrian pathway will be extended further south to O’Connell Street, Kogarah.

The PIR was publicly exhibited from 17 April to 8 May 2019, and is available to view or download on the DPIE Major Project website.

Submissions received will be considered by DPE in their assessment of the project.

Our construction activities will have a temporary impact on open space and the recreational facilities at Rockdale Bicentennial Park. We understand how important this area is for you so we are planning to upgrade existing facilities at Ador Park and McCarthy Reserve, Rockdale and Brighton Memorial Playing Fields, before construction starts.

We have developed a concept design and Review of Environmental Factors (REF) for the proposed recreational facilities at Rockdale and Brighton- Le-Sands, based on your feedback and in consultation with Bayside Council.

The REF outlines the concept design, assesses the potential environmental impacts, and describes what we will do to minimise these impacts during construction and operation of your upgraded recreational facilities. We have developed this REF for the proposed facilities on behalf of Bayside Council.

More information about the concept design is available in our community update (PDF, 2.49Mb) and in the Review of environmental factors (PDF, 9.5Mb).

To make a submission, please visit our interactive portal.

We will:

  • Engage openly with all stakeholders
  • Minimise property needs
  • Develop designs that reduce construction impacts
  • Always work in an environmentally responsible and sustainable manner.

It is anticipated that Section B of the M6 will potentially run from Kogarah to Taren Point via Carlton and Sans Souci, while Section C will potentially run from Taren Point to the A1 Princes Highway in Loftus. There are no plans to further investigate the remaining area (Section D) between Loftus and Waterfall for a motorway connection.

There is currently no timeline, funding commitment or planning approval for Section B or Section C of the Corridor Reserve. However, the road corridor reserved since 1951 for future stages of the M6 remains in place.
