Following that the first of three TBMs to be deployed on Australia’s Torrens to Darlington (T2D) Project has successfully passed its factory acceptance testing in China, has commenced its journey to Adelaide and this Herrenknecht TBM received the green light to be shipped to South Australia.
The process of assembling and launching this TBM at the T2D Project’s Southern Precinct in Clovelly Park will be done after arrival to Adelaide.With the aim of constructing the 4.5km Southern Tunnels, which is due to stretch between the open motorway at Darlington to just south of Anzac Highway in Glandore, this machine is one of two TBMs that will be started up from the Southern Precinct
In order to building the twin 2.2km Northern Tunnels, which are going to run between James Congdon Drive and the existing open motorway south of Grange Road, a third TBM will be commissioned from the Central North Precinct at Richmond. While working on the diaphragm walls for the TBM launch pit has been commenced, the scheduled date for starting digging of the Southern Tunnels by the TBMs is second half of 2026.
The date of commencing work on installing the rebuilt South Road Tram Overpass, a 95m steel arch bridge, is the current month and it requires 1,200 tonnes of structural steel, along with 520m3 of concrete poured into the piles.
As the final 10.5km section of Adelaide’s North-South Corridor, the T2D Project will complete 78km of non-stop, traffic-light-free motorway and drivers will bypass 21 sets of traffic lights as the travel through two separate tunnels, connected by open motorway.
