Infrastructure projects

Infrastructure projects

We are delivering some of the most important road, rail and freight projects in South Australian history. Discover how we are transforming the state.

Building our future, today

We are investing $27.3 billion in transformative infrastructure projects and transport services that will keep our state moving.

This investment means we can build the hospitals that care for our families, the infrastructure that strengthens our economy and the transport networks that move us.

Our pipeline of projects means we have many active work sites across our state. While these may cause temporary disruptions, they are laying the groundwork for a brighter and more connected future.
