Bengaluru Metro completes tunnelling for longest underground line

The Bengaluru Metro Rail Corporation Limited (BMRCL) has successfully completed the tunnelling for the city’s longest underground Metro line, marking a significant milestone for the 13.76 km Pink Line (Reach-6) under Phase-2. Stretching from Kalena Agrahara in the south to Nagawara in the north, the line will feature 12 underground stations, with construction of the stations now 90% complete.

This 20.99 km twin-tunnel route along the North-South corridor is expected to ease Bengaluru’s notorious traffic congestion, offering a faster, more efficient travel option through the city centre.

The final breakthrough came from Bhadra, the last Tunnel Boring Machine (TBM) deployed, which completed a 937-meter stretch from K G Halli to Nagawara. The tunnelling project, managed by ITD Cementation India Limited, included four underground stations: Tannery Road, Venkateshpura, Arabic College, and Nagawara.

Launched in August 2020 with TBM Urja, which started between Cantonment and Shivajinagar, the project utilised nine TBMs, achieving several milestones. Notably, TBM Urja set a record by boring 27 meters in a single day in April 2022, while TBM Tunga completed 308 meters in July 2024.

Scheduled to open in December 2025, the Pink Line will provide a much-needed alternative for commuters along the North-South corridor, reducing traffic strain in Bengaluru. (ET)
