Overview

The Department for Infrastructure and Transport is introducing a Tunnel Protection Overlay that will apply to the River Torrens to Darlington Project (T2D) tunnels.

The Overlay aims to ensure that future development activity and construction work nearby does not impact the tunnels.

As the T2D tunnels are the first major transport tunnels in South Australia, new requirements need to be introduced to guide development near this new type of essential infrastructure.

It’s important that the area immediately around the T2D tunnels is protected from intrusion from structures, such as pilings or basements, or works such as deep excavation, and to ensure development activities don’t create a change in the loading (or weight or stress) that is beyond what has been factored into the tunnel design.

The new requirements are consistent with similar planning measures interstate outlining what builders and engineers will need to consider when designing and building near the tunnels.
