The Bengaluru Metro Rail Company Restricted (BMRCL) achieved a big milestone on Wednesday with the completion of tunnelling for the town’s longest underground Metro line.
A part of the Pink Line (Attain-6) below Section-2, this section stretches 13.76 km between Kalena Agrahara within the south and Nagawara within the north. The 20.99-km twin tunnels, operating alongside the North-South hall, intention to alleviate Bengaluru’s visitors congestion, offering a sooner, extra environment friendly commuting possibility by means of the guts of the town.
The ultimate breakthrough was accomplished by Bhadra, the final Tunnel Boring Machine (TBM) deployed on the road, which lined a distance of 937 metre from Okay G Halli to Nagawara. This part completes the whole tunnelling requirement of Attain-6, marking the end result of 100 per cent tunnelling completion on this line.
The tunnelling from the south of Tannery Street to the north ramp concerned developing 4 underground Metro stations: Tannery Street, Venkateshpura, Arabic Faculty, and Nagawara. This vital section of the venture was managed by M/s ITD Cementation India Restricted, one of many distinguished engineering corporations within the nation.
The tunnelling venture commenced in August 2020 with TBM Urja, which was launched between Cantonment and Shivajinagar. Over the course of the venture, 9 TBMs had been deployed, all of which have now accomplished their assigned segments. BMRCL achieved a number of milestones in tunnelling, with TBM Urja managing the longest single-day progress of 27 meters on April 25, 2022, and TBM Tunga finishing a file 308 meters in a single month between Okay G Halli and Nagawara in July 2024.
The Pink Line contains 12 underground stations in complete, with the work on station building now 90 per cent full. This line is anticipated to make a big impression on visitors circumstances, particularly alongside the North-South axis, providing commuters an alternative choice to Bengaluru’s closely congested roads. The road is predicted to be operational by December 2025.
