Mumbai coastal road: BMC completes 1km of tunnelling work
India’s largest tunnel boring machine (TBM) — Mavla — that is being used for tunnelling work for Brihanmumbai Municipal Corporation’s (BMC) ambitious coastal road project, has completed one-kilometre work on Saturday, at 11.40pm. The tunnel boring work began in January 2021.
Imported from China in May 2020 and assembled here, it is the country’s largest TBM, with a diameter of 12.9 metres.
The 10.58km coastal road that will connect Nariman Point to Bandra Worli Sea Link has twin tunnels of 2.07km, connecting Girgaum Chowpatty to Malabar Hill. Each underground tunnel will have three lanes at a depth of 70 meters. Work is ongoing on the south-bound arm of the tunnel, where 1km of boring work was completed on Saturday. The remaining kilometre of this tunnel will be completed by January.
