The construction for the most-awaited Mumbai Metro-3 is in full tilt. On Thursday, two Tunnel Boring Machines (TBM) which are being used to construct the tunnels for Colaba-Bandra-Seepz Metro 3 project achieved a headway. 

The machines – Krishna 1 and Krishna 2 – were levelled down earlier on September 21 and October 18, respectively, at Naya Nagar’s launching passage in Mahim. Both the machines drilled 2,490 meters underground and came out at the working site near Shiv Sena Bhavan in Dadar. 

Of the 17 tunnel boring machines (TBM) that Mumbai Metro Rail Corporation (MMRC) levelled down, Krishna 1 and 2 were the first to begin the drilling for Metro-3 route. Until now, four TBMs have come out after completing tunnelling for the Metro-3 line. 

It was a big challenge for us and we have successfully met the same. The entire credit goes to the team. For the 32.5 km metro route, 52 km long subway will be tunnelled and 18 km of work has been done,” Managing Director MMRC Ashwini Bhinde said.
