F6 Extension - Stage 1

The F6 Extension Stage 1 is a key element of the NSW Government’s transport vision for NSW, connecting Sydney’s south to the wider motorway network.

Since the NSW Government announced the project in October 2017, Roads and Maritime Services has been developing the project design and conducting field investigations to inform the environmental assessment for the project.

Updates and announcements

F6 Extension Stage 1 - consultation now closed

Roads and Maritime Services invited comments from the community and stakeholders on the F6 Extension Stage 1 in June and July 2018. We would like to thank everyone who provided feedback. While this consultation period is now closed, we welcome ongoing community engagement and feedback on the project which is important to us. You can contact the project team by:

The feedback received on the project between October and December 2017 and our responses are contained within the Community Feedback Summary Report June 2018 (PDF, 4.22Mb) which is available to view or download.

Project background

The M1 Princes Motorway is a key part of Australia’s national highway system, and provides a vital arterial road link through southern Sydney. At present there is no efficient connection to Sydney’s motorway network from the south.

The existing F6 corridor was reserved in the early 1950’s to meet the future needs of the growing populations of southern Sydney and the Illawarra.

The link to the south was identified as a priority in the NSW Long Term Transport Master Plan 2012 and the State Infrastructure Strategy 2014 as one of the future strategic priorities for Sydney’s road network.

Future Transport Strategy 2056, the NSW Government’s 40 year vision for transport outcomes in NSW, has identified the F6 Extension Stage 1 as a priority project for connectivity in Sydney’s south, and to the Illawarra.

What is the F6 Extension Stage 1

The F6 Extension 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 F6 Extension
  • Provision of new shared cycle and pedestrian pathways.

Project benefits

The F6 Extension 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.
  • 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
  • Reduce traffic on General Holmes Drive by 10,000 vehicles a day
  • Contribute to a more accessible, more liveable and productive Greater Sydney.

Project information and design

The project update outlines further details about the design of the F6 Extension Stage 1, including:

  • the proposed tunnel surface connection with President Avenue
  • ventilation facilities
  • tunnel depths and proposed locations for construction sites.

The NSW Government has released this project update to give the community time to consider the information before the environmental assessment phase begins.

An Environmental Impact Statement for the project will be completed.

The NSW Government has announced the F6 Extension program is expected to cost between $2.2 and $2.6 billion. The new tunnel will open to traffic in 2024.

Travel time savings

Traffic congestion currently costs our economy $6.1 billion a year. By the year 2030, this figure will increase to $12.6 billion.

This congestion-busting project will deliver major travel time savings including:

F6 Extension Stage 1Travel Time savings
Kogarah to Anzac Bridge15 minutes
Miranda to Macquarie Park15 minutes
Kogarah to South Sydney13 minutes
Taren Point to Mascot12 minutes
Kogarah to the City8 minutes

Air quality monitoring

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.

A new, tightened regulatory regime on tunnel air quality was announced by the NSW Government in February 2018.

As part of the reforms, the Environment Protection Authority (EPA) will licence the operation of tunnel ventilation facilities. Additionally, the Office of the NSW Chief Scientist and Engineer will review and provide an assurance over air quality considerations of any new tunnel project prior to construction commencing.

The F6 Extension is one of the first transport infrastructure projects in NSW that will be required to undergo additional checks in order to meet new tunnel emission standards.

The air quality considerations will be addressed in the Environmental Impact Statement, which is expected to go on public display later this year.

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

Environmental planning

The F6 Extension Stage 1 is undergoing a rigorous planning process and an Environmental Impact Statement is expected to be released later this year.

The following documents support the planning process to date:

  • Secretary’s Environmental Assessment Requirements
    The DP&E has now issued the Secretary’s Environmental Assessment Requirements for the project. The SEARs establish 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 and Environment (DP&E) early in the planning process to identify issues that must be addressed in the forthcoming Environmental Impact Statement (EIS) State Significant Infrastructure Applications.
  • Scoping Reports
    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 DP&E Major Projects website.

Our commitment

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.
