PM Narendra Modi's visit to Arunachal Pradesh on March 9 marked a significant occasion as he inaugurated the strategically crucial Sela Tunnel. Alongside this monumental project, the Prime Minister laid the foundation stone for approximately 20 other development initiatives in the Northeast region, underscoring the Government's commitment to enhancing infrastructure in the far eastern corner of India.
The visit's centrepiece was the Sela Tunnel, an ambitious road tunnel constructed at an elevation of 3,000 metres in Arunachal Pradesh. It will provide year-round connectivity to Tawang in Arunachal Pradesh, making it the world's longest bi-lane tunnel at 12.04 km. This tunnel is a crucial development ensuring all-weather access to the challenging terrain of Tawang, near the Tibet border, and represents a noteworthy achievement in the region's infrastructure.
The Sela Tunnel will strengthen strategic capabilities along the Line of Actual Control (LAC). Its location near Sela Pass, a crucial point in the region, will play a pivotal role in facilitating troop deployment and the movement of machinery, bolstering India's military presence in the area.
Constructed by the Border Roads Organisation under Project Vartak, the tunnel project holds immense strategic importance in combating external threats. It will significantly reduce travel time and ensure all-weather access along the NH13 road to Tawang, a region known for its picturesque landscapes and cultural heritage.
As a key milestone in India's infrastructure development, the Sela Tunnel will enhance military capabilities and boost tourism in Tawang, offering visitors a smoother and more reliable travel experience. The tunnel's construction using the latest tunnelling methods will ensure uninterrupted travel, contributing to the growth of tourism in the region and positioning Tawang as a popular destination in the North East.
Engage with us in a conversation about the completion of the Sela Tunnel and its profound impact on the local community, tourism, and bolstering internal security.

How long do tunnels last?
Underground structures last a significantly longer life time than above-ground structures. Approximately about 50 years for above-ground, over 100 years for tunnels.

How are tunnels safe?
Civil engineers work hard to build safe, strong tunnels. They know that tunnels have to stand up to forces of tension, torsion, compression, and shearing. Tunnels also need to carry the weight of people and vehicles traveling through them. That is why tunnels are built with strong materials.
