Tunnelling works for the T222 project have completed following the breakthrough of the third drive (TBM 1 refurbished) along the Woodlands Bound tunnel on Apr 27 and the fourth drive (TBM 2 refurbished) along the Changi Bound tunnel on Jun 21 between Outram Park and Havelock Station (800m).
This is the final tunnel to be completed under the C4 team, and the second final project along the overall line to complete bored tunnel excavation works.
