Bengaluru metro’s 21.38-km Pink Line, which will have the city’s longest underground section at 13.9 km, achieved a milestone on Friday when Tunnel Boring Machine (TBM) Vindhya broke through the Shadi Mahal shaft on Tannery Road.
Vindhya is the fifth TBM to complete its designated length of tunnelling. Urja, Varada, Avni and Lavi have already finished their job, according to Bangalore Metro Rail Corporation Limited (BMRCL).
The BMRCL deployed a total of nine TBMs to tunnel 21.245 km on two sides of the 13.9-km section.
