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.

The major subsurface problems in tunneling and underground works include issues such as squeezing ground conditions, upheavals, tectonic stresses, popping, rock bursting, high temperature gradient, heavy ingress of water during execution, existence of large shear zones, flowing ground conditions, abrupt change in strata conditions, low cover zones or very high cover/ overburden and emission of methane and other gases etc.

How safe are underground tunnels?
Tunnels particularly transit and transport tunnels—are viewed as high-risk, high-damage-potential targets because of the confined spaces and the numerous patronage present in a single location.

What technology is used to detect tunnels?
The Synchronized Electromagnetic Gradiometer uses the enhanced conductivity associated with tunnels as compared to the surrounding medium, to detect the tunnels. A low-frequency electromagnetic signal is used to illuminate the area of interest.

What gases are in tunnels?
Harmful gas in tunnel engineering is usually refers to gas, methane(CH4), carbon dioxide(CO2), hydrogen sulfide(H2S) and ammonia gas. These harmful gases occur frequently in the coal bearing strata of relatively closed structures and may also occur in non coal strata.

How does tunnel ventilation work?
Tunnel ventilation systems are designed to maintain safe air quality both inside and outside the tunnel to meet stringent air quality standards. Ventilation systems work by drawing in fresh air from the tunnel entry, which is then pushed through the tunnel by the movement of vehicles and jet fans.

How do water tunnels work?
Various methods are used to construct underwater tunnels including an immersed tube and a submerged floating tunnel. The immersed tube method involves steel tube segments that are positioned in a trench in the sea floor and joined together. The trench is then covered and the water pumped from the tunnel.
