F6 Extension - Stage 1

Roads and Maritime Services has taken the first step in planning for the F6 Extension Stage 1 project by lodging a State Significant Infrastructure Application. Since the NSW Government announced the project in October 2017, Roads and Maritime has conducted field investigations, market sounding and extensive community engagement.

Updates and announcements

Roads and Maritime submitted a State Significant Infrastructure (SSI) Application to the Department of Planning and Environment (DP&E). An SSIA is lodged early in the planning approvals process for the F6 Extension Stage 1 to identify topics that must be assessed in an Environmental Impact Statement (EIS).

An SSI Application is accompanied by a scoping report, which provides early details of the project, potential impacts during construction and operation, and details the proposed environmental studies to be undertaken and assessed during the next stage of the planning process.

The DP&E has now issued the Secretary’s Environmental Assessment Requirements (SEARS) for the project. The SEARs establish the subject matter that must be addressed and responded to in the EIS.

For more information about the SSI Application process, and the options assessment for this project, please see our SSI Application Fact Sheet (PDF, 608Kb) and F6 Extension Stage 1 Options Fact Sheet. (PDF, 2.78Mb).

To see the F6 Extension Stage 1 SSI Application, you can visit the Department of Planning and Environment website and see the Scoping Report (PDF, 43Mb).

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 1950s 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.

What is the F6 Extension Stage 1?

Following geotechnical investigations in 2016 and 2017 the NSW Government has decided to progress the F6 Extension Stage 1 – New M5 Arncliffe to President Avenue, Kogarah to the next phase of the planning and project development. Roads and Maritime has now started community consultation for the project on the preliminary design. 

Roads and Maritime is proposing a four kilometre continuous twin tunnel.  The north and south twin tunnels will connect with the New M5, 75 metres underground, passing under Rockdale to an interchange at President Avenue, Kogarah. The F6 Extension Stage 1 will be designed with a provision for a future extension south.

The detailed design for the tunnel has not been finalised. We will carry out consultation and design work, and come back to the community with further details in mid-2018.  

Project benefits

The F6 Extension Stage 1 will provide a connection for motorists from Southern Sydney to the wider Sydney motorway network, improve travel times between southern Sydney and Sydney CBD and ease congestion on the local road network.

Stage 1 will:

  • 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
  • Enable motorists to better access the Sydney motorway network
  • Assist in the reduction of traffic congestion, particularly along the Princes Highway through Arncliffe, Rockdale and Banksia, and the Grand Parade, Brighton-le-Sands, and provide shorter travel times for road users
  • Provide a motorway that is safe and reliable for road users
  • Improve the amenity of the foreshore precinct at Brighton-le-Sands at the Grand Parade
  • Reduce the number of heavy vehicles on surface roads by up to 2000 per day
  • Allow motorists coming to or from the north to avoid Sydney Airport traffic.

Improving travel times

This project will deliver time savings of:

  • Kogarah to the City of around 5 minutes
  • Taren Point to Mascot of around 10 minutes
  • Kogarah to south Sydney of around 10 minutes
  • Kogarah to Rozelle of around 8 minutes.

Community engagement

A summary of all the feedback received to date from the pop up information sessions and online consultation will be available soon.

Next steps

Roads and Maritime is continuing investigations in the study area between Arncliffe and Kogarah. Investigations will include surface water monitoring, flora and fauna surveys, geotechnical and utility investigations involving drilling, and background air quality monitoring.

Further investigations will also continue to help determine any possible corridor adjustments for the future motorway between Kogarah and Loftus.

There are no plans to investigate the remaining section of the corridor between Loftus and Waterfall as part of the early investigation work.

If we are carrying out investigations near your property we will notify you in writing prior to starting work.
