13 November 2021 Current Affairs:The Border Roads Organisation (BRO) is building the world’s longest bi-lane road tunnel, the “Sela Tunnel,” on the Balipara-Chariduar-Tawang (BCT) road as part of Project Vartak.

Highlights:
♦ The Sela tunnel is being built on the Indo-China border at a height of 13,800 feet.
♦ It is being built on the 317-kilometer BCT road. 
♦ The BCT route connects Arunachal Pradesh’s East Kameng, West Kameng, and Tawang districts to the rest of India.
♦ It is being built to provide Tawang with all-weather connectivity.
♦ The tunnel would also allow for more efficient movement of troops and weapons along the Line of Actual Control (LAC).
♦ Sela Tunnel connects Tawang and West Kameng districts by cutting through the Sela–Charbela ridge.

Sela Tunnel
♦ Sela Tunnel is a 3,000-meter-long road tunnel currently under development. It will provide all-weather communication between Assam’s Guwahati and Arunachal Pradesh’s Tawang.
 ♦ It’s being dug beneath the 4,200-meter Sela Pass on the Trans-Arunachal Highway’s NH 13 section.
♦  A new 12.4-kilometer road will connect the tunnel to NH 13. The distance between Dirang and Tawang will be cut in half.
♦  It began construction in 2019 and is expected to be finished in February 2022. 
♦ This project consists of two 1,790 m and 475 m long tunnels, as well as a 980 m long escape tube. It will save you an hour of travel time.
