Adelaide Slashes Speed Limits, Electrifies Two Rail Lines by 2026

The City of Adelaide endorsed its Integrated Transport Strategy on 22 July 2025. This replaces the earlier Smart Move Transport and Movement Strategy that covered 2012 to 2022. The new strategy includes a City-Wide Speed Limit Review that is examining targeted speed reductions rather than a uniform city-wide limit. Reduced speeds on Park Lands Roads and West Terrace are scheduled for implementation by the end of 2026.

South Australia launched its Transport Strategy 2025 earlier in the year. That document includes work on public transport needs for regional centres and the development of a state-wide public transport strategy. The Australian Government has committed $6 million in total, with $5 million allocated to rail extensions and $1 million to rail decarbonisation planning. This funding supports electrification of the Outer Harbor and Belair lines.

Changes for daily travel in Adelaide

Greater Adelaide’s public transport improvements are planned over a two to four year pipeline. The work targets expanded rail capacity in the city hub and extensions of rapid transit to north, northwest and south growth areas. These steps are intended to address future congestion costs that are forecast to reach $7.5 billion by 2051.

Residents who drive on Park Lands Roads and West Terrace can expect lower speed limits once the changes take effect by late 2026. People using the Outer Harbor and Belair rail lines may notice service changes as electrification planning and rail extensions progress with the allocated federal funding. The timelines mean some impacts will appear within the next 18 months while others will roll out over the following years.

Next steps in the review process

The City-Wide Speed Limit Review continues to assess specific locations for speed reductions. Implementation on the named roads remains on track for the end of 2026. Rail projects supported by the $6 million commitment are part of the broader improvements pipeline that extends into the late 2020s. Residents can track updates through the City of Adelaide’s published documents on the Integrated Transport Strategy.

The state’s Transport Strategy 2025 runs alongside these city-level actions. It coordinates regional and state-wide public transport planning. Together the documents provide the current framework for when and where transport changes will occur in Adelaide.
