## Resource

South Australia’s $15 billion Torrens to Darlington project is transforming inner western suburbs with three colossal tunnel boring machines—Mary, Catherine, and Elizabeth—carving a 78-kilometer traffic-light-free motorway. Aerial shots reveal homes and businesses cleared for the massive upgrade, while officials remain confident it’s on track and on budget despite global inflation pressures. The Auditor-General has raised concerns, but department heads say Middle East conflict hasn’t significantly impacted costs—and completion by 2031 is still the goal. This unprecedented engineering feat marks the final leg of the North-South Corridor, reshaping the state’s infrastructure landscape.
