India is engaged on constructing its first underwater tunnel beneath the Brahmaputra River in Assam. The tunnel is 15.6 km lengthy and is designed as a twin-tube tunnel, whereas the undertaking is estimated to price Rs 14,900 crore. The Public Funding Board (PIB) has given its clearance to the undertaking, which is but to get a nod from the Union Cupboard. The large construction is being constructed 32 metres beneath Brahmaputra’s deepest mattress degree. After the development is accomplished, it is going to turn into one among India’s most bold and sophisticated civil engineering initiatives in historical past.
The Defence Ministry will present 20% of the funds for the undertaking, whereas the remaining 80% can be funded from the Ministry of Highway Transport and Highways, making the undertaking related for each civilian and defence functions.
What are the options of the underwater twin-tube tunnel in Assam?
The dual-tube tunnel is a four-lane engineering surprise constructed deep beneath the riverbed. It’s designed as two unidirectional tunnels with every having two lanes. Because the tunnel is being constructed close to the China border, it has a strategic relevance to it.
What are the advantages of the tunnel undertaking?
The tunnel will massively cut back the journey time between Numaligarh and Gohpur, from 240 km to only 34 km. The commutation will even be diminished from greater than 6 hours to only half an hour. The tunnel will even present easy accessibility to Arunachal Pradesh, Manipur, and different northeastern states. With journey time diminished, the tunnel will facilitate sooner deployment of defence personnel and tools. With this, civilian journey will turn into safer, particularly throughout the monsoon season, the time when ferry and bridge routes typically get caught.
Chief Minister Himanta Biswa Sarma was impressed by the Atal Tunnel within the Himalayas. The thought for this stemmed from there, which turned a very long time want right into a nationally recognised strategic hall, bridging the hole between the 2 banks of the Brahmaputra nearer than they have been earlier than.
The undertaking is permitted by the Nationwide Board for Wildlife, however it should undergo a collection of environmental checks, together with research on sediment patterns, groundwater motion, and seismic resilience, important for a tunnel of this scale.
