Mumbai: The Mumbai Metro Rail Corporation (MMRC) on Monday said it had completed 2,192 meters of tunnelling for the Mumbai Metro Line 3, which runs from Cuffe Parade to SEEPZ.
The corporation has deployed eight tunnel boring machines (TBM) at four locations — Azad Maidan, Naya Nagar in Mahim, Vidyanagari in Kalina, and at Marol Naka.
The TBM at Mahim was the first to start operations in November, 2017, and has completed one kilometre of the 2.5 km tunnel it will be constructing to Dadar. The TBMs at Azad Maidan, Kalina and Marol Naka are tunnelling to Grant Road, domestic airport and the international airport respectively.
MMRC has so far received 11 TBMs. According to Ashwini Bhide, Managing Director, MMRC, “It is indeed a milestone to complete more than two km of tunnelling in a short span. With 15 TBMs already having completed Factory Acceptance Test (FAT), we hope to have all 17 TBMs running by July 2018.”
The 33.5 km corridor will have 27 stations at an estimated cost of ₹23,136 cr.
