November Tunnel Progress

November 13
TBM2 docked into the Upper Cross Street retrieval shaft earlier today. The completion of this Expo bound tunnel structurally links the network of DTL tunnels from Gali Batu to Bedok Reservoir on both bounds.

November 23
The BP Bound TBM has just launched at the Stadium Shaft towards Tampines Central. This is also the final TBM launch out of the Stadium Shaft. Breakthrough is estimated around Chinese New Year 2015.

For the month of December, we can look forward to the
- Breakthrough of Expo Bound TBM between Stadium Shaft and TPC (926)
- Breakthrough of BP Bound TBM between Prison Shaft and BDR (926)
- Breakthrough of Expo Bound TBM between UPC and XPO (923)
