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.

What are the main components of tunnel?
a) Main components of the urban tunnelling process:-
1) Soil, 2) lining, 3) TBM, 4) existing infrastructure, 5) grouting, 6) alignment.
b) Tunnel information model with components modeled on different LoDs:- soil, lining, TBM and
buildings data can be represented on different LoD.

What are the design factors of tunnels?
The second factor to consider is the tunnel geometry and alignment, which include the tunnel diameter, length, depth, curvature, slope and cross-section shape. These parameters affect the choice of tunneling method in terms of the equipment size, capacity, flexibility and performance.

How do we make a tunnel project?
1.Bearing courses and concrete structures are built into the tunnel.
2.Cable routings are built inside the exit level.
3.Building cable troughs and connecting tunnel structures.
4.Electrical and HVAC work starts.
5.Blocks and ballast into the tunnel.

What is the use of tunneling techniques?
Tunneling is often used in virtual private networks. It can also set up efficient and secure connections between networks, enable the usage of unsupported network protocols and in some cases allow users to bypass firewalls.

What is the main purpose of tunnel?
Tunnels are used for a wide variety of purposes. They provide essential links in many highways, railroads and urban rapid transit systems. Urban water supply and distribution, sewage collection and disposal, hydroelectric power generation, flood control and mining require extensive tunneling.

Why do tunnels collapse?
When tunneling begins, the stress of surrounding rock is readjusted and redistributed, worsening the parameters of physical mechanics and causing the displacement of surrounding rock and slackness, so tunnel collapses when the surrounding rock has no self-stableness and the supporting structure has not timely.
