Today marks a historic moment for India with the inauguration of the Sela Tunnel by Prime Minister Narendra Modi, signifying a pivotal advancement in enhancing connectivity and security along the China frontier.
Constructed by the Border Roads Organisation (BRO) at a cost of ₹825 crore, this infrastructure marvel stands at an altitude of 13,700 feet in the West Kameng district, offering a lifeline to the region, especially the strategic Tawang area where Indian and Chinese troops clashed in December 2022.
Recognized as the world's longest twin-lane tunnel at an altitude exceeding 13,000 feet, the Sela Tunnel comprises of Tunnel 1 (a 980m single tube tunnel) and Tunnel 2 (a 1555m twin tube tunnel). The latter includes one bi-lane tube for traffic and an escape tube for emergencies.
The tunnel system is complemented by a seven-kilometer approach road to Tunnel 1 and a 1.3-kilometer link road connecting Tunnel 1 to Tunnel 2.
This engineering marvel not only addresses the lack of motorable roads and rail connections in Arunachal Pradesh but also strengthens India's infrastructure along the China border.
