Two rail corridors from the city - one south towards Aldinga and Sellicks Beach and one north towards Roseworthy and Concordia - will be preserved by the state government to cater for future housing development.

It says securing these corridors will unlock more transit options for the outer southern suburbs, which the Greater Adelaide Regional Plan (GARP) forecasts to grow by 23,000 homes, and the northern outer suburbs, expected to grow by 82,000 homes. 

The state government launched its Transport Strategy on 16 March, which outlines a 30-year vision to transform how people and goods are moved around the state.

This supports the GARP, which will also be released this week, by guiding development of a transport network that provides safe and affordable options and identifies future transport corridors that will support new housing and economic opportunities.

The Transport Strategy sets the overall direction for future transport planning and will guide decisions on which projects to prioritise and invest in.

More than 6000 people participated in community engagement shaping the strategy, which included virtual reality hubs across the state, an online survey and written submissions.

This engagement allowed South Australians to identify what was most important to them when it comes to transport and their future needs, with 10 per cent of respondents planning to use their car less in the future.

Around 24 per cent of respondents said they wish to use public transport more often and 44 per cent said they want to walk, run and cycle more.

Some of the key priorities identified in the strategy include improving the quality of roads, public transport and active transport options to support housing and population growth.

It identifies that efficient supply chains strengthen the state’s competitiveness, driving economic opportunity, and that a safer and more accessible public transport system will be required to meet the needs of an ageing population.

Another priority is to reduce the environmental impact of the transport network.

Planning Minister Nick Champion says it’s important to plan for future infrastructure requirements to support growth. 

“This is planning and transport working together to get a better outcome for South Australians in the future. 

“Proper planning ensures our city will remain a liveable and attractive place with coordinated transport options.”
