- The Sela Tunnel is the longest bi-lane road tunnel in the world.
- The total length of the project, including the tunnels, the approach and the link roads, will be around 12 km.
- The tunnel is being constructed by the Border Roads Organisation at an altitude of 13,800ft near the Indo-China border.
- It is being built on the 317km long Balipara-Charduar-Tawang (BCT) road which connects West Kameng, East Kameng and Tawang districts of Arunachal Pradesh to the rest of the country.
Why is the project important?
- All-weather connectivity to Tawang and other forward areas in the sector will be the most important advantage that the project promises.
- At the moment, Sela pass stays closed for a few winter months.
- The project will provide a new alignment on the axis towards the LAC, and allow movement of military and civil vehicles all through the year.
Significance of the tunnel
- China is undertaking massive infrastructure development and troop build-up in the Rest of Arunachal Pradesh (RALP) area.
- In military parlance, the RALP is an area in Arunachal Pradesh other than the Kameng area.
- Other than the Kameng area consisting of East and West Kameng districts, the rest of the State is referred to by the Army as the RALP.
