Bored tunnelling works for TBM 1 completed earlier this week, concluding the 18 months long Changi bound tunnel drive from Lentor to Mayflower station through the 5XO site. Its sister TBM 2 is 91% out of the 970-ring drive and targeted to complete by the end of the month. The tunnel roof structure of the 5XO is completed and backfilling works have commenced. Structural works for the station entrances are progressing on the surface level.
