Mumbai Plans 70km Underground Tunnel Network as Third Transport Mode

The Mumbai Metropolitan Region Development Authority (MMRDA) has initiated the process for a Detailed Project Report (DPR) for a proposed 70-kilometer underground tunnel road network, intended to serve as Mumbai's third major mode of transportation, complementing existing road and metro systems. This ambitious project will be implemented in three phases, catering to current and future mobility demands.

The network is designed to seamlessly link critical infrastructure, including the Mumbai Coastal Road, the Bandra-Kurla Complex (BKC) High-Speed Rail Station, and the Chhatrapati Shivaji Maharaj International Airport. Maharashtra Chief Minister Devendra Fadnavis highlighted that this initiative is crucial for Mumbai's development as a global economic hub, aiming for efficient movement of people and goods.

Deputy Chief Minister Eknath Shinde emphasized that the tunnel network will introduce a 'third dimension of mobility' beneath the surface, integrating with metro and coastal corridors to realize the vision of 'Mumbai in Minutes'. The three planned phases are a 16-km Worli Sea Link-BKC-Airport Loop, a 10-km East-West Link, and a 44-km North-South Corridor.

MMRDA Metropolitan Commissioner Sanjay Mukherjee stated that the DPR will thoroughly assess the project's technical feasibility, environmental impact, and economic viability. A consultant has been appointed to study geological, environmental, and socio-economic factors, prepare tunnel designs, and assist with the bidding process. The project aims to function as a subterranean expressway, drastically cutting travel times between key areas like South Mumbai, BKC, and the airport, while alleviating traffic on major surface roads.

Impact: This project is expected to have a substantial positive impact on the Indian infrastructure and construction sectors. Companies involved in large-scale tunneling, civil engineering, and material supply are likely to benefit. The enhanced connectivity and decongestion could also boost economic activity in Mumbai, indirectly benefiting related industries. The scale of the project positions it as a significant infrastructure development for India. Rating: 7/10
