BMC completes 1,000 m tunneling work on north-bound arm of coastal road
THE BRIHANMUMBAI Municipal Corporation on Friday said it has completed 1,000 m (50 per cent) of tunneling work between Girgaum Chowpatty and Priyadarshini Park on Nepean Sea Road, which is the north-bound arm of the civic body’s Rs 12,000-crore Coastal Road project.
The tunneling is being done using the Tunnel Boring Machine, Mavala. Imported from China in May 2020 and assembled here, it is the largest TBM in the city and the first-of-its-kind used for undersea tunnel boring. It has a diameter of 12.9 metres and weighs 2,119 metric tonnes.
The coastal road that will connect Nariman Point to Bandra-Worli Sea Link has twin tunnels of 2.07 km, connecting Girgaum Chowpatty to Malabar Hill. Each underground tunnel will have three lanes at a depth of 70 metres.
