South Australia’s River Torrens to Darlington (T2D) project has offered a glimpse of the tunnelling operation, with a new scale model of a tunnel boring machine (TBM) unveiled.
The 2.7m, 80kg TBM was commissioned from manufacturer Herrenknecht and follows the specifications of the TBM that will be used in construction of the T2D.
This will be around 100m long and weigh up to 5000 tonnes.
The robotic model allows visitors a sense of the scale and technical expertise required to deliver the project, which will see more than 6km of tunnels constructed for the motorway.
Works continue on east-west connections to allow for smoother operation of the road network once the T2D project is complete, with new plans unveiled to reroute Raglan Avenue traffic north via a new road link, creating an upgraded four-way intersection with Edward Street.
The Price Street and South Road intersection upgrade will include the installation of traffic signals, pedestrian crossing and right hand turn access lane into Castle Plaza Shopping Centre from South Road – preserving Price Street as a residential zone.
Main works are scheduled to commence in early 2025, with the project expected to open to traffic in late 2025.
Community members can visit the T2D Community Information Centre at 290 South Road, Hilton to provide feedback on the concept plan.
