Sela Tunnel: World’s Highest Bi-Lane Road in Arunachal Pradesh

Arunachal Pradesh, the "Land of Dawn-Lit Mountains," beckons adventure seekers and nature enthusiasts with its breathtaking landscapes, rich cultural heritage, and ancient monasteries. Nestled amidst the majestic Himalayas, this northeastern state boasts one of India's most remarkable engineering feats - the Sela Tunnel.

For decades, travellers venturing to Tawang, the crown jewel of Arunachal Pradesh, had to navigate the treacherous Sela Pass. This high-altitude mountain pass, perched at over 13,700 feet, was prone to harsh weather conditions and year-round snowfall, often restricting access to Tawang for several months. However, the inauguration of the Sela Tunnel in March 2024 by Prime Minister Narendra Modi has transformed travel in the region.

Constructed by the Border Roads Organisation (BRO), the Sela Tunnel is a marvel of modern engineering. This high-altitude tunnel, the world's longest bi-lane tunnel at this height, bypasses the Sela Pass, ensuring year-round connectivity to Tawang. The tunnel complex consists of two tunnels and a link road, allowing for a seamless and swift passage through the once-daunting mountain pass.

With the ease of access provided by the Sela Tunnel, Arunachal Pradesh tourism is expected to flourish. Several tour operators are now offering Tawang tour packages, catering to various interests and budgets. These packages typically include visits to the Tawang Monastery, the largest Buddhist monastery in India, exploration of the serene Gompas (monasteries) scattered across the region, and excursions to natural wonders like the Shonga-Tser Lake.

For the intrepid traveller, an Arunachal Pradesh Road trip offers an unparalleled adventure. The state boasts a network of scenic highways, winding through lush valleys, cascading waterfalls, and snow-capped peaks. A road trip itinerary can be customized to include visits to Bomdila, another beautiful hill station, Dirang, famous for its hot springs, and Ziro Valley, a UNESCO World Heritage Site known for its rice paddies and tribal villages.

On Saturday, March 10, 2024, Prime Minister Narendra Modi inaugurated the Sela Tunnel in Arunachal Pradesh, marking the debut of the world's longest twin-lane tunnel. This strategic infrastructure project is poised to significantly enhance connectivity in the region, reinforcing the government's commitment to bolstering transportation networks in challenging terrains.

Sela Tunnel, a recent engineering marvel, is a tunnel situated in the enchanting region of Arunachal Pradesh. Connecting the Tawang district with the rest of the state, this tunnel has not only facilitated transportation but has also opened doors to the breathtaking beauty of the Himalayan region.

Who built Sela Tunnel?

The Sela Tunnel, situated at an elevation exceeding 13,000 feet, is poised to become the world's longest bi-lane tunnel, strategically addressing challenges posed by snowfall and landslides on the Balipara-Chariduar-Tawang Road. Orchestrated by the Border Roads Organisation (BRO), the project encompasses two tunnels and a link road.

Tunnel 1 spans 980 metres, featuring a single-tube design, while Tunnel 2, stretching 1,555 metres, is a twin-tube structure with one dedicated bi-lane for traffic and the other for emergency services. Connecting these tunnels is a 1,200-metre link road, ensuring seamless connectivity.

The foundation stone for the Sela Tunnel project was ceremoniously laid by Prime Minister Modi on February 9, 2019. The realization of this ambitious venture demanded an impressive effort, with over 90 lakh man-hours contributed by an average of 650 workers and labourers daily over the past five years.

The construction entailed the use of substantial resources, including approximately 71,000 metric tonnes of cement, 5,000 metric tonnes of steel, and 800 metric tonnes of explosives. The Sela Tunnel not only exemplifies engineering prowess but also signifies a significant stride towards bolstering all-weather connectivity in the challenging terrains of Arunachal Pradesh.

The Sela Tunnel comprises two tunnels with different lengths:

  1. Tunnel 1: This tunnel is a single-tube structure and spans a length of 980 meters.
  2. Tunnel 2: This tunnel is a twin-tube structure, and one of the tubes is dedicated for traffic while the other is designated for emergency services. Tunnel 2 has a length of 1,555 meters.

These tunnels, along with the link road between them, contribute to the Sela Tunnel project's goal of providing all-weather connectivity in the challenging terrain of Arunachal Pradesh.

The Sela Tunnel connects Tawang to the Balipara-Chariduar-Tawang (BCT) Road in Arunachal Pradesh, India. The tunnel is strategically designed to provide all-weather connectivity for the region, overcoming challenges posed by snowfall and landslides on the BCT Road. Tawang, a district in Arunachal Pradesh, is a significant location with historical and cultural importance, and the Sela Tunnel aims to enhance accessibility to this region.
