To build world-class transport infrastructure in the entire belt of north eastern region, Indian Railways, Ministry of Road Transport and Highways, and Ministry of Defense (Border Roads Organisation) will jointly build the triple tunnel project at a cost of about ₹7,700 crore. The project is a strategically important integrated multi-modal rail and road transport corridor, which will be the first of its kind in the country. Under the project, two road tube tunnels and one rail tube tunnel will be built under the Brahmaputra River. Apart from this, a rail-road infrastructure will also be created for the rail-road missing links including several new rail lines, a loop line, a railway station, and a station yard. With the help of this mega rail-road transport corridor, military vehicles, logistics ammunition, and armed forces can reach the China border of North Assam, Tawang, and Arunachal Pradesh at a much faster pace.
Apart from this, a 121.33 km-long new railway line will be laid between Rangpara and Tawang and will connect Tawang, Senga, Rupa, Bhalukpong and Rangpara. A new railway line will also be laid between Dhalaibil-Jakhlabandh and DekragaonJamugurihar. In addition, a new railway station is proposed to be built between Dhalaibil and Jamugurihar with an increased number of platforms and a loop line and station yard. There are plans to lay an additional rail line between South Portal and Silghat on priority. The Dhalaibil-Jakhlabandh link does not have rail or road connectivity therefore; the connectivity will be strengthened by building a rail-road corridor connecting the missing link.
