The final blast for the 980-metre long Sela Tunnel (Tunnel 1) was conducted by Director General Border Roads (DGBR) Lt Gen Rajeev Chaudhry through an e-ceremony from New Delhi on January 22, 2022. This marks the culmination of the excavation works on the complete Sela Tunnel Project. This feat has been achieved by Border Roads Organisation (BRO) amidst inclement weather and heavy snowfall.
The Sela Tunnel Project is located in the West Kameng District of Arunachal Pradesh. Once completed, it will be a lifeline as it will provide all weather connectivity to Tawang. The project comprises of Tunnel 1, which is a 980 m long single tube tunnel and Tunnel 2, which is a 1555 m long twin tube tunnel. Tunnel 2 has one bi-lane tube for traffic and one escape tube for emergencies. It will also be one of the longest tunnels to have been constructed above altitude of 13,000 feet. The project also includes construction of an approach road of seven kilometres to Tunnel 1, which takes off from BCT Road and a link road of 1.3 kilometres, which connects Tunnel 1 to Tunnel 2.
The foundation stone of the Sela Tunnel Project was laid by the Prime Minister Shri Narendra Modi in 2019. On January 15, 2021, after the first blast was conducted by the DGBR, excavation work on Tunnel 1 commenced. Thereafter, on October 14 2021, Raksha Mantri Shri Rajnath Singh carried out the breakthrough blast of the 1,555 meter Tunnel 2, through an e-ceremony from India Gate, marking the end of excavation on Tunnel 2.
