Introduction

In July 2024, the Indian government is expected to float tenders for an underwater rail tunnel as part of the Mumbai-Ahmedabad High-Speed Rail (MAHSR) project. This project, overseen by the National High-Speed Rail Corporation Limited (NHSRCL), aims to significantly reduce travel time between the two cities.

Project Overview

The Mumbai-Ahmedabad High-Speed Rail project encompasses a 508-kilometer-long rail corridor. The planned underwater section will span 21 kilometers, of which 7 kilometers will be under the sea. The total estimated cost for the project is ₹1.08 lakh crore.

Underwater Rail Tunnel Details

The underwater rail tunnel will pass beneath the Thane Creek. The tunnel will be constructed using the New Austrian Tunnelling Method (NATM) and will include a single-tube system. This section is designed to withstand a variety of challenges, including earthquakes and high water pressure.

Tendering and Construction

The tenders, scheduled to be floated in July 2024, will cover the design and construction phases. The construction phase is anticipated to take approximately 6.5 years. The NHSRCL is overseeing the project, which involves advanced engineering and safety protocols for the underwater segment. This involves significant geotechnical surveys and detailed risk assessments to ensure the tunnel’s integrity and safety.

Financial and Environmental Considerations

The project’s total cost is estimated at ₹1.08 lakh crore, with funding from various sources. The environmental impact of the underwater rail tunnel India construction is being carefully managed through comprehensive environmental impact assessments. The MAHSR project is also expected to generate numerous employment opportunities during its construction and operational phases.

Conclusion

The Indian government plans to issue tenders in July 2024 for the construction of an underwater rail tunnel as part of the Mumbai-Ahmedabad High-Speed Rail project. This tunnel will span 21 kilometers and is designed to enhance the rail network, reducing travel time between Mumbai and Ahmedabad.

National High-Speed Rail Corporation Limited (NHSRCL)

The NHSRCL is a company responsible for the implementation of the Mumbai-Ahmedabad High-Speed Rail project and other high-speed rail projects in India.
