Day 9, S603 Breakthroughs

At last, the entire DTL2 is structurally linked underground. S603 has came a long way from King Albert Park, tunnelling the 1.3km long Expo Bound tunnel before successfully docking at the Sixth Avenue station on Thursday morning (May 8). A short timelapse of the machine from delivery point is featured in this update. Photos of the breakthrough will be updated in the subsequent tunnelling progress posts. The next breakthrough of S605 is estimated to take place at BTN within the next 10 days.

  1. Can you update DTL2 tunnelling progress, especially S605? Btw, where is S605 now? How many more rings to breakthrough?
