The Namma Metro's Tunnel Boring Machine 'Bhadra' achieves breakthrough at K.G. Halli metro station, marking the completion of a tunneling process.
The Tunnel Boring Machine (TBM) ‘Bhadra’ of the Namma Metro achieved a breakthrough at K.G. Halli metro station on Thursday evening (February 8).
Commencing its journey in February 2023, it successfully tunnelled a distance of 1185.8 metres from Venkateshpura.
The event was attended by Deputy Chief Minister D.K. Shivakumar as Bhadra achieved its second milestone. The initial breakthrough occurred on June 24, 2021, when it was launched from Venkateshpura to construct an 841.1-metre southbound tunnel leading to Tannery Road. The tunnelling process concluded on December 16, 2022.
Subsequently, the second phase involved the excavation of a 1,186-metre northbound tunnel towards K.G. Halli, which commenced on February 16, 2023, and was successfully completed on Thursday, February 8.
Bhadra is set to be recovered and deployed for its last tunneling 935-metre towards Nagavara from K.G. Halli — the commencement of the third and final drive, marking the culmination of the Pink Line.
Under Phase 2 of the project, the Reach 6 line is from Kalena Agrahara to Nagawara totalling 21.26 km with 18 stations. It consists of an Elevated section of 7.50 km with 6 stations from Kalena Agrahara to Tavarekere and Underground section of 13.76 km with 12 Stations from Diary Circle to Nagavara.
According to Bangalore Metro Rail Corporation Limited (BMRCL), Pink Line will be operational in 2025
According to the “2023: World Air Quality Report”, India is the third most polluted nation globally and Delhi the most polluted capital city. Though Bengaluru (Rank 673) stands nowhere close to the topmost polluted cities, increasing temperature, irregular rains, growing population and infrastructure are leading to a slow change in the water and air quality of the garden city.
