Transportation Planning Casebook/Sydney F6 Motorway
Sydney’s population increase over the past decade has been a major contributor to traffic delays in the southbound and northbound roads. In the recent years, WestConnex’s expansion of the M4 and M5 helped ease the congestions of motor vehicles in residential/ commercial areas. The F6 Extension Stage 1 is another Sydney project which is currently under the initial planning phase. South Sydney experiences daily road congestion and unreliable travel time, especially between Kogarah and Sydney CBD on the Princess Highway.
Stage 1 of the F6 motorway is a 4 km link road which will connect President Avenue, Kogarah to the new WestConnex M5 motorway at Arncliffe. This will provide quick connects to Sydney CBD, M4, Inner west and Parramatta as it lies parallel to Princess Highway and avoids 26 sets of traffic lights. By reducing the number of trucks on roads and improving travel time for all travellers, the F6 motorway aims to aid the residential areas of Kogarah by providing more quieter streets. In addition, local road users and busses will have easier accessibility to inner roads without having to wait in traffic. This will ultimately support the future growth of South Sydney by connecting it to the Greater Sydney region for increased productivity.
Additional benefits include:
- Easy access bicycle and pedestrian pathways
- Over 3250 jobs created during construction phase
- Improved air-quality
Stage 1 of the F6 extension is currently at its environmental impact stage with construction beginning in 2020 and aiming to be complete by 2024. After stage 1 is complete the F6 extension aims to expand from Sydney CBD to Loftus, approximately 20 km. The total cost of this project is said to be around $3 billion AUD.
- Twin tunnels linking President Avenue at Kogarah to M5 motorway at Arncliffe.
- Tunnels stubs constructed for future F6 extension
- Minor upgrades to President avenue & Princess highway to accommodate for the increase in vehicle capacity.
- Larger pedestrian and bicycle pathways between Bestic Street, Brighton – Le- Sands to Civic Avenue, Kogarah.
- New bridge over President Avenue, Kogarah.
- Additional power supply lines in the area.

Policy & Service IssuesEdit
During October and December, Roads and Maritime (RMS) ran community engagements and consultations to gather feedback on the concept design of the new F6 Extension Stage 1.
There was significant backlash from the South Sydney community in regards to air pollution and acquisition of local parkland, Rockdale Bicentennial Park to be specific.
In summary, the feedback focussed on seven key topics:
- Community amenity, health and safety (19%);
- Property and access (19%);
- Local traffic (15%);
- Air quality (14%);
- Environmental impacts (13%);
- Construction impacts (7%);
- Public and active transport infrastructure (4%);
- Other (9%).
The Environmental Impact Statement (EIS) extensively details the assessment and solutions to many of the issues brought to light by the community of Southern Sydney in significant detail. The main issues and responses can be summarised in the table below:
|Community Concern||RMS Response|
|Community amenity, health and safety|
|Safety of all road users, in particular the impacts that the developments would have on pedestrian safety.||The tunnel will not be accessible by pedestrians or bicycles.
RMS is investigating surface options for cyclists and pedestrian infrastructure to be incorporated into the design.
|Project impacts on local community gardens, greenspace and facilities.
Concerns in regards to losing local sporting fields (Rockdale Bicentennial Park, skate park)
|RMS has been working closely with Bayside and the local community on how best to restore the facilities. The amenities will be upgraded. During construction, the skate park will be relocated.|
|Property and Access|
|Concerns about land acquisitions||F6 Extension Stage 1 has been designed to minimise impact to property; i.e. underground tunnels.
Using existing RMS owned land
|Vibration and Noise Pollution||Dilapidation surveys, any damage to be rectified at no cost to the landowner.
Noise and vibration limits, monitoring systems and mitigation measures will be put in place.
An acoustic shed will be installed to act as a noise barrier to construction noise.
|Concerns in regards to worsening local traffic conditions.
Additional heavy vehicle movements.
|Transport movements to be scheduled outside peak travel times whenever possible.
During operation, traffic will be reduced, bus travel times will be improved.
Link to and extension of existing shared cyclist and pedestrian path.
|Location of unfiltered ventilation outlets in close proximity to schools, hospitals, play fields and parks, and young children and the elderly.||A scientific review on the impact of the emissions from tunnel ventilation was undertaken. The findings indicated that the emissions would have negligible impacts on the local communities given the height at which the emissions would be released.
Monitoring of emissions will occur 24/7 in line with new EPA regulations for tunnel emissions.
|Habitats for native flora and fauna within Rockdale Bicentennial Park and local fish species.||No presence of endangered native species.
Temporary loss of aquatic and riparian habitat to be reinstated with trees, wetlands and vegetated area to be replaced.
|Contaminated spoil removal, air pollution (dust) and increased heavy vehicle movements.||Limiting construction hours, acoustic sheds to manage spoil ad noise.
Permanent operational infrastructure will be built as well as drainage and water management facilities. Road pavement and finishing works will occur at the end of the project.
|Public and Active Transport Infrastructure|
|Requests for the provision of additional pedestrian crossing and/or bridges.||RMS, with Bayside Council, are investigating surface options for cyclists and pedestrian infrastructure to be incorporated into the project design.|
|Project cost and tolling concerns.||Project cost: $2.2-$2.6 billion.
Tolled road to provide a fair and equitable means to help fund the project. i.e. people using infrastructure will help pay for it and ongoing maintenance.
|General suggestions on alternative alignment and size of project.||General comments in regards to future transport strategies as issued by Transport for NSW.|
