Shenton Way - Tunnelling Completes

Bored tunnel works for the T225 project completed in the early hours of today with the docking of TBM 2 at Maxwell station. Tunnelling works were unique in this project due to the stacked configuration of the 2 launch shafts, one of which is within the permanent structure of the station. Geological constraints were also experienced beneath McCallum St resulting in prolonged delays and the eventual re-sequencing of the TBM drives.

T225 is the 3rd last team to complete tunnelling works for the line, ahead of T222 later this month and subsequently T216 in Q4.
