Infrastructure

From investing in roads, public transport and new infrastructure to creating jobs, the Department for Infrastructure and Transport provides opportunities and improves the lives of South Australians.

$21 billion infrastructure investment

We are investing in the future, committing $21 billion to new and upgraded infrastructure over four years from 2023–24. This investment means we can continue to build new and better roads, intersections, bridges, rail and social infrastructure that will benefit current and future generations of South Australians.

This busy pipeline of projects means we have many active work sites across the state, causing unavoidable short-term disruptions such as traffic delays and temporary rail closures. However, this short-term inconvenience will be far outweighed by the long-term benefits of these exciting projects.
