The Sela Tunnel is the longest bi-lane road tunnel in the world. It is being built by the Border Roads Organization at an altitude of 13,800ft near the Indo-China border.
This tunnel is being constructed on the 317km long Balipara-Charduar-Tawang (BCT) road which links West Kameng, East Kameng, and Tawang districts of Arunachal Pradesh to the rest of the country.
The world’s longest bi-lane road tunnel is going to provide all-weather connectivity to Tawang. Also, it will secure better movement of troops and weaponry to different locations along the Line of Actual Control (LAC) with China.
