A total of eight Tunnel Boring Machines (TBM) named TUNGA were deployed to complete the tunneling work, which is part of the Pink Line’s Reach 6, Phase 2 project, covering a 13.76 km stretch between Kalena Agrahara and Nagawara.
In a statement, Bengaluru Metro Rail Corporation Limited (BMRCL) announced that tunneling for this segment began on February 3, 2024. With today’s breakthrough, 20,582.7 meters out of the total 20,992 meters of tunneling have been completed, marking 98% of the overall project.
