Mumbai’s TBM-driven tunnel work advances under two major road schemes: the Goregaon–Mulund Link Road (GMLR) and the Mumbai Coastal Road. Sources report that a second tunnel boring machine begins excavating twin GMLR tunnels, while other coverage highlights upcoming TBM operations for coastal road tunnelling between Kandivli and Malad.

For GMLR, reports say both twin tunnels beneath the Sanjay Gandhi National Park area are now under excavation, with the first TBM (“Tulsi”) already having bored hundreds of metres and the second (“Vihar”) starting after passing a site acceptance test. The project is described as building twin three-lane tunnels with TBM-driven excavation for most of each tunnel length, supplemented by box tunnels, ramps, and shafts, and connecting Goregaon East with Mulund West.

For the Coastal Road, coverage focuses on BMC’s plan for twin underground tunnels using large TBMs, with completion targeted for 2027. One outlet also flags potential environmental impact in the project’s influence zone, while other GMLR-focused reporting concentrates on construction milestones, machine specifications, and affected structures and removals.
