F6 Extension - Stage 1

In October 2017, the NSW government announced it will proceed with 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 F6 Extension 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 F6 Extension Stage 1 is a key part of this strategy, supporting safe, efficient and reliable journeys for people and freight.

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
  • 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 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.
  • 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:

F6 Extension 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 F6 Extension 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 F6 Extension 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 and Environment (DPE) 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. Submissions received will be considered by DPE in their assessment of the project.

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.
