DTL2 January Tunnelling Overview

C918A diagram (1) from TKK launch shaft

An overview of the progress of the remaining 5 tunnels for stage 2:

S604 at 405 rings (~61% completed)
S605 at 209 rings (~31% completed)

S608 at 105 rings (~51% completed)

2nd route of grouting on S603 has completed. 602 is now going through its first round of soil improvement works near The Cascadia POB. Right lane of the corridor road has been temporarily closed to facilitate space for the site works.

I'm expecting S608 to be our next breakthrough at Queen St next month, followed by S604 at BTN.
