Bengaluru Metro’s longest underground section is set to achieve another construction milestone as the Tunnel Boring Machine Tunga will make its second breakthrough on Wednesday.
This will be the 21st out of 24 tunnelling assignments to be completed on the 21.26-km Pink Line, which will connect Kalena Agrahara to Nagavara via MG Road and Tannery Road.
The German-made Herrenknecht machine was first launched in the city on July 23, 2021, and took 13 months to tunnel 1,260 metres between Venkatespura and Tannery Road. Its second assignment began on October 31, 2022, to bore through rock, soil and a mixture of both between Venaktespura and KG Halli.
