Big milestone for Mumbai’s Underground Mobility Project: Orange Gate–Marine Drive Tunnel Begins Main Drive The Orange Gate–Marine Drive Road Tunnel, one of India’s most complex urban road tunnelling projects, has reached another historic milestone with the main tunnelling drive now officially underway. This is a pivotal moment for Mumbai’s underground mobility network. Purpose-built for Mumbai’s challenging coastal geology, the Tunnel Boring Machine — India’s largest slurry shield TBM for an urban road tunnel — achieved a crucial breakthrough recently, and has since advanced rapidly, excavating an impressive 70 metres within a few days. Hon’ble Chief Minister Shri Devendra Fadnavis and Hon’ble Deputy Chief Minister & MMRDA Chairman Shri Eknath Shinde had launched the TBM on December 3, 2025. The project involves the construction of twin tunnels spanning over 7 km. The first tunnel, currently under construction, extends 3.45 km, reaching depths of up to 52 metres, while passing beneath the Central and Western Railway corridors and Mumbai Metro Line 3 with exceptional safety and engineering precision. Once complete, the project will reduce travel time between Orange Gate and Marine Drive to just 5 minutes, enabling seamless East-West connectivity, direct integration with the Coastal Road and Atal Setu, and significantly reducing congestion, fuel consumption and emissions. Following the launch, the project has achieved several key milestones, including the lowering of the backup system unit of the TBM and connecting it to the TBM shield, before successful completion of the initial tunnelling drive. It has now commenced the main drive operations. Progressing rapidly December 3, 2025: ✔️ TBM launched December, 2025- January 2026: ✔️ Backup system unit lowered and connected to the TBM shield ✔️ Hydraulic and electrical connections completed ✔️ Flowmeters, densitometers, pressure sensors calibrated ✔️ Probe drill unit installed and tested January 8, 2026: ✔️ Initial drive begins; temporary rings erected. January 26, 2026: ✔️ Permanent rings erection begins January 31, 2026: ✔️ Initial drive completed February 26, 2026: ✔️ Transition to main drive completed February 28, 2026: ✔️ Main drive operations commence. TBM Mining Progress (March 26, 2026): ✔️ 70 m excavated out of 3,720 m #MumbaiInMinutes #MMRDA #ReimaginingMMR #UrbanRoadTunnel #OrangeGateTunnel #DiggingDeep #OrangeGateToMarineDrive #UrbanTunnel #UndergroundMobility #MegaProject #TransformingMMR #MumbaiInMinutes #UrbanInnovation #InfrastructureForFuture #RebootingMumbai #ReshapingMMR #SmartMobility Devendra Fadnavis Eknath Shinde - एकनाथ शिंदे MAHARASHTRA DGIPR Dr. Sanjay Mukherjee
