India’s Longest Urban Tunnel Between Borivali and Thane (GS Paper 3, Growth & Development)

Introduction

• On July 13, 2024, Prime Minister Narendra Modi inaugurated the groundbreaking ceremony for the Thane-Borivali Twin Tunnel project in Mumbai.
• This ambitious Rs. 16,600 crore project is part of a larger Rs. 29,000 crore infrastructure development initiative aimed at significantly improving Mumbai's transportation network and connectivity.

 

Overview of the Thane-Borivali Twin Tunnel Project

• Project Cost: Rs. 16,600 crore.
• Length: 11.8 km.
• Connectivity: Direct subway line between Thane and Borivali, ending at Borivali on National Highway 8.
• Travel Time Reduction: From over an hour to just 12 minutes.
• Distance Reduction: 12 km.
• Lanes: Two regular lanes and one emergency lane.
• The Thane-Borivali Twin Tunnel project is designed to provide a seamless and rapid transit option between Thane and Borivali.
• By reducing the travel time from over an hour to just 12 minutes, the tunnel will greatly enhance the efficiency of commuting, offering a significant improvement in connectivity within Mumbai.
• The inclusion of two regular lanes and one emergency lane ensures that the tunnel can handle a substantial amount of traffic while providing a safe and reliable route for emergency situations.
•  

Strategic Implications and Benefits

• The Thane-Borivali Twin Tunnel is not only a transportation link but also a strategic solution to alleviate traffic congestion on key routes such as Ghodbundar Road and the Western Express Highway.
• By offering a direct and rapid route, the tunnel aims to improve east-west suburban connectivity, streamline travel, and prevent road overcrowding.

 

Key Benefits:

• Traffic Decongestion: The tunnel will help reduce traffic on major roads, leading to smoother and faster travel.
• Economic Growth: Improved connectivity can boost economic activities by facilitating easier movement of goods and people.
• Enhanced Quality of Life: Reduced travel time and congestion will improve the daily commute for residents, enhancing their overall quality of life.
• Sustainability: By cutting down on travel time and distance, the tunnel will also contribute to reducing vehicle emissions, promoting environmental sustainability.

 

Environmental and Technical Details

• Environmental Impact: The project is designed to be environmentally friendly, with no impact on the adjacent Sanjay Gandhi National Park.
• Tunnel-Boring Machine: India’s longest tunnel-boring machine will be used, capable of boring a tunnel 10.25 km long with cross passages every 300 meters for safety and maintenance.
• Carbon Emission Reduction: The project is expected to reduce carbon emissions by 150,000 metric tons per year.

 

Environmental Considerations:

• The project emphasizes minimal environmental impact, particularly with regard to the Sanjay Gandhi National Park, a crucial green space in Mumbai.
• By using advanced technology and environmentally sustainable practices, the project aims to achieve its infrastructural goals without compromising the ecological balance.

 

Technical Advancements:

• The use of India’s longest tunnel-boring machine, capable of boring a tunnel 10.25 km long, demonstrates the project's commitment to leveraging cutting-edge technology.
• Cross passages every 300 meters will ensure safety and ease of maintenance, making the tunnel a robust and reliable infrastructure asset.
