On Tuesday, the Brihanmumbai Municipal Corporation (BMC) successfully completed the boring work for the second and final undersea tunnel of the Mumbai Coastal Road Project (MCRP). The drilling operation, which began on April 26, 2022, concluded slightly over a year later
This achievement marks a significant milestone for the civic body, as it strives to open the coastal road by the year’s end. The twin tunnels, spanning 2.07 kilometres, were excavated using a Chinese Tunnel Boring Machine (TBM) named Mavala, after Shivaji’s mountain warfare experts. The digging process commenced in January 2021, and the breakthrough for the first tunnel occurred in January 2022. Subsequently, the TBM was maneuvered leftwards, towards the northbound tunnel, utilising a hydraulic-jack powered turn-table, facilitating a 180-degree rotation
