The Seaford Rail Extension project will provide a new electrified passenger railway and a 5.5 kilometre extension of the dual track rail line from Noarlunga Centre Railway Station to Seaford.
This project will also involve:
* New stations and bus / train interchanges at Seaford Meadows and the proposed Seaford Rail Terminus.
* A 1.2 km elevated bridge over the Onkaparinga River, River Road and a rail bridge over Old Honeypot Road.
* Three road bridges over the rail track at Goldsmith Drive, Seaford Road and Lynton Terrace.
* New access pathways and footbridges at selected locations.
* Park and Ride facilities at selected stations.
* Parking for car and bicycle for commuters.
* Landscaping and urban design features at selected locations along the new rail corridor.
Preparation works recently concluded and pre-construction activities such as surveying, geotechnical drilling and Aboriginal Heritage surveys commenced on-site. In addition, a significant planning, design and environmental assessment study has commenced which will involve consulting with the community about issues associated with the proposed works.
Construction works on the Seaford Rail Extension is expected to start in mid 2010 and is scheduled for passenger operation in 2013, in line with the completion of the electrification of the Noarlunga line.
The $291.2 million Seaford Rail Extension project will significantly improve public transport rail services for the community in the rapidly expanding southern suburbs well into the future.
Project timeframes
Preparation works for the extension recently concluded and pre-construction activities such as surveying and geotechnical drilling have commenced on-site.
Construction work on the Seaford Rail Extension is expected to start in mid 2010, with the new line scheduled for passenger operation in 2013, in line with the completion of the electrification of the Noarlunga line.
Benefits
Integrating land use with public transport
Improvements to the reliability and speed of public transport services will attract Transport Orientated Developments (TODs). This in turn will assist higher density living areas along transport corridors. As such, the project is essential to the development of a more efficient, urban form of transport for Adelaide.
Reduced travel time
Providing a rail service to the Seaford District Centre is expected to reduce public transport travel times by up to 15 minutes on a trip to Adelaide. This service is expected to attract approximately 6,000 public transport trips per weekday and around 1.7 million trips per annum. The existing rail line to Noarlunga has the second highest patronage with only the Gawler line having greater patronage.
Improved access to everyday facilities
Extending rail services to Seaford will improve access to everyday facilities such as work, schools and shopping centres for all community members. The extension may assist in reducing community severance and improve general wellbeing for those living in the rapidly expanding southern suburbs.
Reduced pollution
The extended rail line to Seaford is expected to bring about a significant reduction in cars using the road network resulting in reduced air and noise pollution.
Employment
The work on the extension of the metropolitan rail network to Seaford is expected to create more than 400 jobs over four years.
Key features
The extension will include:
* New stations and bus / train interchanges at Seaford Meadows and the proposed Seaford Rail Terminus.
* A 1.2 km elevated bridge over the Onkaparinga River, River Road and a rail bridge over Old Honeypot Road.
* Three road bridges over the rail track at Goldsmith Drive, Seaford Road and Lynton Terrace.
* New access pathways and footbridges at selected locations.
* Park and Ride facilities at selected stations.
* Parking for car and bicycle for commuters.
* Landscaping and urban design features at selected locations along the new rail corridor.
The chosen route
The extension will provide 5.5 kilometres of rail line from Noarlunga to Seaford. A station in Seaford Meadows, a 1.2 kilometre dual track bridge over the Onkaparinga River and a terminus close to the Seaford Shopping Centre will also be constructed.
The existing dual track rail line at Noarlunga Centre will be extended under Goldsmith Drive and down to the Onkaparinga Valley estuary where it will cross over Old Honeypot Road. From this point, the rail tracks will cross River Road and the Onkaparinga Valley estuary on a 1.2 kilometre viaduct and bridge which will then run adjacent to Sauerbiers Road to the Seaford Meadows Station.
From the Seaford Meadows Station, the alignment continues under Seaford Road and Lynton Terrace and terminates at the Seaford Interchange.
The South Australian Government owns and is the development authority for all land along the Seaford Rail Extension corridor.
Please see the attached map for more detail of the corridor.pdf.
Stations locations
Stations will be located at Seaford Meadows and the Seaford Rail Terminus.
Property acquisition
There will not be any properties acquired or demolished.
The local environment
An environmental study and engagement with the local community will help to identify the measures required to protect the local environment.
Why do we need the Seaford Rail extension?
The southern suburbs have recently experienced a rapid growth in population. The Onkaparinga South Coast area was the second fastest growing area between 1991 and 2007. The Tea Tree Gully North area was the first fastest growing area.
There will be an additional 9000 dwellings in the southern areas of Adelaide by 2025. These increases in population will lead to increasing pressure on the supply of housing, offices, appropriately skilled labour and transport services.
The extension of passenger rail services to the growing population centre of Seaford will significantly improve transport access to this area.
