Torrens to Darlington Project

Named and blessed 🎉

📽️ Watch key moments from the official blessing ceremony of the first of three large Tunnel Boring Machines (TBMs) that will deliver the T2D Project.

The TBMs were named after prominent South Australian suffragists - Mary Lee, Catherine Helen Spence and Elizabeth Webb Nicholls.

The names were chosen following an overwhelming response from the community, with more than 2,000 submissions received.

The third and final Tunnel Boring Machine (TBM) cutterhead has been lowered into the launch box at the T2D Project’s Central North Precinct in Hilton. Each cutterhead was lifted and lowered by a 500-tonne gantry crane.

With the cutterhead now in place, the remaining TBM components will be assembled, before final testing and commissioning ahead of tunnelling beginning in the second half of 2026.

Have a look at what's happening inside one of SA's largest sheds 👀👇

This massive 285m-long shed at Waterloo Corner has already manufactured 1,000 precast tunnel-lining segments that are ready for installation in the T2D Project tunnels.

More than 55,000 concrete segments will be manufactured to line both the Northern and Southern Tunnels, supporting approximately 60 local jobs at peak production.

Once manufactured, the segments will be transported to the Tunnel Boring Machine (TBM) launch areas, where they will be placed on high-tech battery-electric Multi-Service Vehicles (MSVs), which will deliver them to the TBMs to construct the tunnel walls.

Assembly of the two Tunnel Boring Machines (TBMs) at the Southern Construction Precinct is progressing well. Meet Construction Manager Derek Whelan as he takes us inside the launch box, where crews are busy preparing for tunnelling to begin in the second half of this year.

This Mother’s Day, meet Project Engineer Nur Amalina Noorazmi and experience a day on site through the eyes of her children, Khadija (9) and Ayoub (5).

Balancing motherhood and engineering, Amalina brings patience, resilience and leadership to the Project, while inspiring the next generation of dreamers and thinkers.

Today, and every day, we recognise and celebrate the incredible superhero mums helping deliver the T2D Project.

We’ve made it easier to get from South Road into the city. 🚗

The upgraded intersection at James Congdon Drive and Sir Donald Bradman Drive opened earlier this year, improving access from the western suburbs and making it safer for cyclists and pedestrians.

Here’s what this means for you:

✅ Three new right-turn lanes from James Congdon Drive onto Sir Donald Bradman Drive
✅ Extra through and turning lanes to keep traffic moving
✅ Upgraded pedestrian crossings
✅ New Shared Use Paths for cyclists and pedestrians

This upgrade forms part of the broader network upgrades package within the River Torrens to Darlington (T2D) Project, helping the road network operate efficiently during construction and into the future.
