The Thane-Borivali Twin Tunnel project is a significant infrastructure development aimed at improving connectivity between Thane and Borivali in Mumbai. Here are the key facts about the project:
Concept and Initial Planning
- The idea for a direct road tunnel connecting Thane and Borivali was first proposed to alleviate the heavy traffic congestion on the Ghodbunder Road and Western Express Highway.
- Early feasibility studies and initial planning were conducted by the Mumbai Metropolitan Region Development Authority (MMRDA) to assess the viability and environmental impact of the project.
Feasibility Studies and Approvals
- Comprehensive feasibility studies were carried out, focusing on geological surveys, environmental impact assessments, and cost analysis.
- The project received necessary clearances from environmental and other regulatory authorities, ensuring minimal impact on the Sanjay Gandhi National Park.
Project Announcement:
- The Thane-Borivali Twin Tunnel project was formally announced as part of a broader infrastructure development initiative for Mumbai. This was aimed at enhancing urban connectivity and reducing travel times.
Tendering and Contractor Selection:
- The tendering process for the construction of the tunnels was initiated by MMRDA. Several national and international construction companies participated in the bidding process.
- A joint venture between Larsen & Toubro (L&T) and Megha Engineering & Infrastructures Limited (MEIL) won the contract to undertake the construction of the tunnels.
Foundation Stone Laying Ceremony:
- On July 13, 2024, Prime Minister Narendra Modi laid the foundation stone for the Thane-Borivali Twin Tunnel project, marking the official commencement of construction activities.
Construction Phase:
- The construction involves the use of advanced Tunnel Boring Machines (TBMs) to excavate the tunnels beneath the Sanjay Gandhi National Park at a depth of 23 meters. This method ensures minimal disruption to the environment.
- The tunnels will have three lanes each, including one emergency lane, to facilitate smooth and safe travel.
Current Status and Future Outlook:
Once completed, the Thane-Borivali Twin Tunnel is expected to significantly reduce travel time between Thane and Borivali to just 12-15 minutes, greatly easing traffic congestion and improving connectivity in the Mumbai metropolitan region
As of now, the project is in the initial stages of construction, with significant progress expected in the coming years.
