Excavation at the Tagore cut and cover tunnel has completed and the base slab has been concreted between GL5-7. Excavation of the tunnels between TGR and LTR are progressing. The Woodlands bound tunnel is now at ring 99 (12% completed). The TBM boring the Changi bound tunnel is experiencing problematic ground conditions over the past month, and regular interventions are being carried out to unclog the cutters (ring 60, 7% completed)
