TBM Renny is constructing the parallel tube tunnel.


West End Connectors, a consortium of Aecon, Dragados and Ghella, was awarded the Advance Tunnel contract in 2021 and launched the two TBMs in 2022. As TBM boring comes to an end for the machines,


work will continue at the extraction shaft to lay the foundations and form the structure of the future tunnel portal.

Work has also started to prepare construction sites


for the eastern underground segment of the line that will run from east of Jane Street to Mount Dennis Station. In February, Strabag was awarded the Advance Tunnel


2 contract to design, build and finance this section. The contract includes a 546 yd (500m)-long tunnel from east of Jane Street to Mount Dennis Station.
