Upper Thomson Diverts

After 3 months of preparation works, Sato Kogyo has successfully implemented their first traffic diversion along Upper Thomson Road at Lakeview, where the future launch shaft (ULS) sits. The old pedestrian overhead bridge (POB) will be demolished at once, and piling works will begin for the launch shaft by year end once the site is cleared.

Upper Thomson Launch Shaft (ULS)
ULS will launch out 3 Slurry TBMs - 1 which will do a double drive to Upper Thomson, and another 2 towards Caldecott station. A Slurry Treatment Plant (STP) and Gantry Crane will be constructed along the former road. The team hopes to launch the first TBM by the end of 2015. Excavation of the tunnels will take some 18-24 months, and might possibly drag on into early 2018. Once the tunnels have its first stage concrete (FSC) completed, the cross passage within the shaft will been built. The shaft will be backfilled and reinstatement on the surface will only take place then.

Canal diversion work is still on going at the station side. For the ERSS, Upper Thomson would be implementing the diaphragm wall construction. Trenching works should begin by year end.

  2. In view of recency of developments the posts may not always follow the alphanumeric ordering of the lines' station. More pertinent updates will receive priority, such as this post which features the recently diverted Upper Thomson Road. You can expect an update for the Sin Ming station, now called Bright Hill, tentatively on 17 Sep.
