Prime Minister Narendra Modi marked a significant milestone today during his visit to Arunachal Pradesh by inaugurating the Sela Tunnel, a crucial infrastructure development connecting Tezpur to Tawang. Constructed at a hefty cost of ₹825 crore, this tunnel serves as a vital link near the Line of Actual Control (LAC) with China, overcoming the challenges of inclement weather and difficult terrain.
Outlined below are five key points regarding the Sela Tunnel:
1.Longest Bi-lane Tunnel at High Altitude: The Sela Tunnel stands as an engineering marvel, being hailed as the world’s longest bi-lane tunnel at an elevation exceeding 13,000 feet. Its primary objective is to ensure all-weather connectivity, addressing the issues posed by heavy snowfall and frequent landslides along the Balipara-Chariduar-Tawang Road.
2.Project Execution: Executed by the Border Road Organisation (BRO), the project comprises two tunnels and a link road. Tunnel 1 stretches 980 meters in length, serving as a single-tube tunnel, while Tunnel 2, spanning 1,555 meters, consists of twin tubes. One tube facilitates traffic flow, while the other is reserved for emergency services. Connecting these tunnels is a link road covering 1,200 meters.
3.Initiation and Manpower: Prime Minister Modi laid the foundation stone for the Sela Tunnel project on February 9, 2019. The completion of this extensive undertaking demanded over 90 lakh man-hours, with an average of 650 workers and laborers dedicatedly contributing on a daily basis over the past five years. The construction process involved approximately 71,000 metric tonnes of cement, 5,000 metric tonnes of steel, and 800 metric tonnes of explosives.
4.Modern Features for Safety: Incorporating modern amenities, the Sela Tunnel is equipped with features such as jet fan ventilation, firefighting equipment, and SCADA-controlled monitoring systems to ensure enhanced safety and operational efficiency.
5.Strategic Significance: Positioned 400 meters below the Sela Pass, this tunnel assumes critical importance, especially during the harsh winter season. It facilitates swift movement of troops, weaponry, and machinery along the Sino-Indian border, bolstering strategic defense measures.
The inauguration of the Sela Tunnel by Prime Minister Narendra Modi underscores a significant achievement in enhancing connectivity and bolstering security infrastructure in the region. This monumental project not only symbolizes India’s commitment to modernizing its transportation networks but also serves as a testament to its strategic preparedness along the borders.https://www.ndtv.com/india-news/5-facts-about-the-worlds-longest-bi-lane-sela-tunnel-set-to-be-inaugurated-by-pm-modi-5204917
