The Orange Gate–Marine Drive Urban Road Tunnel project, overseen by the Mumbai Metropolitan Region Development Authority (MMRDA), has reached a significant engineering feat. The south-bound Tunnel Boring Machine (TBM) has successfully navigated beneath seven active Central and Harbour Railway tracks without disrupting train services.
This complex operation took place beneath one of Mumbai’s most bustling railway crossings, ensuring seamless railway operations above ground. Continuous 24x7 monitoring, stringent safety protocols, and tight cooperation between Central Railway and the Commission of Railway Safety ensured the safe progress of the TBM beneath the railway corridor.
This achievement marks a major step forward in the construction of twin underground road tunnels connecting Orange Gate with Marine Drive. The project, which began earlier this year, involves navigating challenging urban and coastal geological conditions, necessitating the TBM to pass through existing railway infrastructure and Mumbai Metro Line 3.
