Foundation Stone and Construction Timeline

The foundation stone for the Sela Tunnel project was laid by Prime Minister Narendra Modi in February 2019. Construction work commenced in April of the same year, with the first blast occurring at Portal 4 of Tunnel 2 on October 31, 2019. The estimated cost of the project is Rs. 697 crore. As per the current timeline, the Sela Tunnel is expected to be completed and opened in October 2023.

Design and Location of Sela Tunnel

The project is strategically located at an altitude above 13,000 feet near the Sela Pass. The need for this infrastructure arises from the prolonged closure of the Balipara-Charduar-Tawang road due to heavy snowfall. By providing all-weather connectivity, the Tunnel will significantly enhance the Indian military’s capabilities along the Line of Actual Control (LAC).

The design and configuration of the tunnels and approach roads have been modified since the initial contract award. Tunnel 1, previously planned as a 475-meter single-tube tunnel, has now been extended to a length of 980 meters. Tunnel 2, initially slated to be 1790 meters long, has been redesigned as a bi-lane tunnel spanning 1555 meters. Notably, Tunnel 2 includes an emergency escape tube to ensure the safety of travelers. The approach roads consist of a 7100-meter stretch leading to Tunnel 1, a 1340-meter road connecting the two tunnels, and a 340-meter approach road to Tunnel 2.

Current Status and Future Projection

In January 2022, a significant milestone was achieved with the final tunnel breakthrough of Tunnel 1, measuring 980 meters in length. The project remains on track to meet its completion deadline by October 2023. Once operational, the Sela Tunnel will serve as a crucial lifeline, enabling seamless connectivity between Guwahati and Tawang, transcending geographical barriers and opening new avenues for development.

This project signifies the government’s commitment to infrastructure development, ensuring year-round accessibility and fostering economic growth in Arunachal Pradesh. With its strategic location and transformative potential, the tunnel will revolutionize transportation, promoting connectivity, and advancing the region’s overall development.

As the Sela Tunnel project progresses toward completion, it stands as a testament to India’s determination to enhance connectivity, strengthen security, and bolster socioeconomic progress in the beautiful region of Arunachal Pradesh.
