Mumbai's ambitious Goregaon-Mulund Link Road (GMLR) project has reached a critical tunnelling stage, with the first Tunnel Boring Machine (TBM), 'Tulsi', already 64 metres into excavation beneath Sanjay Gandhi National Park. The 5.3-km twin-tunnel project connects Goregaon (East) to Mulund (West). The second TBM, 'Vihar', is 92% complete in assembly and will commence excavation from October 22, following successful Site Acceptance Tests.
The twin tunnels will extend 4.70 km each, with diameters of 14.20 metres along parallel stretches and 13 metres within the SNGP area. Once operational, the 12.20-km GMLR aims to cut travel time from around 90 minutes to just 20 minutes, significantly easing congestion and providing a faster link between Mumbai's western suburbs and Thane, Navi Mumbai, and Mulund.
