SELA (WEST KAMENG/TAWANG): It’s an engineering marvel below approach at an altitude of over 13,000-feet in icy chilly climate to bolster all-weather connectivity and swifter navy deployments to the essential Tawang and Kameng areas of Arunachal Pradesh alongside the China frontier.
The Border Roads Group (BRO) is feverishly working to finish the over Rs 700 crore Sela Tunnel undertaking, which consists of two tunnels and method roads, earlier than the deadline of August subsequent yr.
Introduced within the 2018-2019 price range, the longer of the 2 bi-lane tunnels is 1,555-metre, whereas the opposite is 980-metre. The longer tunnel has two tubes, the primary one and an “escape” one for emergency use.
“We hope to finish the undertaking by June subsequent yr. The Sela Tunnel will then turn out to be the world’s longest bi-lane street tunnel above the peak of 13,000 ft,” stated undertaking director Colonel Parikshit Mehra, an M Tech from IIT Delhi who labored for 5 years within the development of the Atal Tunnel at Rohtang.
The present 317-km lengthy Balipara-Charduar-Tawang (BCT) street meanders its approach by the Sela Cross at an altitude of 13,800-feet on solution to Tawang. “The Sela Cross is seen to the Chinese language from the Line of Precise Management. That’s militarily disadvantageous for us. The brand new tunnel will move below the Sela Cross,” stated a senior officer of the Military’s 4 Corps.
Furthermore, the BCT street regularly will get blocked on the Sela Cross for each navy and civilian visitors throughout three months within the winters resulting from heavy snowfall. “It turns into a logistical nightmare and requires huge snow clearance work,” stated Col Mehra.
Being constructed utilizing the “newest Austrian tunnelling methodology”, the Sela Tunnel is far beneath the snow line, which can enable all weather-travel with out the challenges of snow clearance.
The tunnel’s overhead clearance can be excessive sufficient to permit all navy automobiles to move by it. This may guarantee troops and heavy weaponry like artillery weapons could be swiftly rushed to Tawang from the 4 Corps headquarters within the plains of Assam to satisfy any contingency. “The tunnel will minimize the travelling distance by solely 6-km. However it’ll guarantee all-weather connectivity and minimize travelling time by an hour,” stated Col Mehra.
Presiding over the “breakthrough blast” of the primary tube of the tunnel to mark the tip of its excavation by video-conferencing final week, defence minister Rajnath Singh stated the Sela Tunnel “will play a vital position in bolstering nationwide safety and guaranteeing socio-economic growth” of the area.
The Sela Tunnel’s development has progressed at a speedy clip, with the excavation work on the 980-metre second tunnel additionally having already crossed the 780-metre mark.
Col Mehra’s lengthy stint on the Atal Tunnel, which is the world’s longest freeway tunnel at 10,000-feet, has helped quite a bit. “There was very poor geology there. The expertise has helped me to take preventive steps to keep away from deformations and collapses right here,” he stated.
