Sela Tunnel project in Arunachal Pradesh | The Dawn
Here’s What Makes 1.55 km Sela Tunnel Of Strategic and Historical Significance
A strategic tunnel under construction in Arunachal Pradesh will be ready ahead of deadline by June 2022, permitting swifter deployment of weapons and soldiers to forward areas near the Line of Actual Control (LAC) in Tawang sector in all-weather conditions, officials familiar with the development said on Thursday.
The Sela tunnel, a ₹700-crore project announced by the government in 2018, will be the longest twin-lane tunnel above 13,000 feet in the world, and will cut down travel time to Tawang by at least one hour as well as provide all-weather connectivity.
Winter connectivity to Tawang over the 14,000-foot pass, Sela, posed a logistics challenge for the army for decades, with the movement of men, weapons and stores severely affected for at least three months. The Sela project, being executed by the Border Roads Organisation (BRO), involves the construction of three tunnels -- a main tunnel, an escape tube, and a shorter third tunnel -- and a road connecting the main and the third tunnels. The tunnels are coming up through two ridges west of the Sela pass. The main and escape tunnels are 1,555 metres long each, the shorter tunnel 980 metres and the road stretches 1,200 metres (only tunnels longer than 1,500 metres have to have an escape passage alongside).
