Historic Approval for India's First Twin-Tube Underwater Tunnel in Assam

The approval of India's first twin-tube underwater road-cum-rail tunnel in Assam has been hailed as a significant milestone by Arunachal Pradesh's Deputy Chief Minister, Chowna Mein. Announced by the Centre, this ambitious project is set to dramatically improve connectivity in the Northeast, fostering economic growth and enhancing strategic infrastructure.

The Union Cabinet, led by Prime Minister Narendra Modi, has green-lighted the development of a 33.7 km four-lane access-controlled National Highway, featuring a 15.79 km underwater twin-tube tunnel beneath the Brahmaputra River. This includes a railway provision in one tube, a major advancement in regional logistics.

Constructed between Gohpur and Numaligarh in Assam, this initiative is estimated to cost Rs 18,662 crore. The project is expected to bolster economic development between Assam and Arunachal Pradesh, ease transportation, and support growth under India's Act East Policy.
