Welcome to the River Torrens to Darlington Project

Part of Adelaide's North-South Corridor

The T2D Project is the final 10.5km section of the North-South Corridor, and will complete 78km of non-stop, traffic light-free motorway between Gawler and Old Noarlunga. Drivers will be able to bypass 21 sets of traffic lights as they travel through two separate tunnels, connected by an open motorway.

A preferred Alliance partner has been selected to deliver this important project, a consortium comprising John Holland, Bouygues Construction, Arcadis Australia, Jacobs and Ventia. These companies individually have an extensive track record of successfully delivering major tunnelling and infrastructure projects around the country and internationally.

Engagement events

The T2D Alliance team is visiting locations along the alignment throughout December to share project information and answer any questions you may have.
