PM Modi inaugurates

One Nation Tunnel


Due to its geography Kashmir was always difficult to access for the rest of India. That long standing need for road connectivity has now been fulfilled by opening the Chenani- Nashri tunnel on the Jammu-Srinagar National Highway.


Recently inaugurated by Prime Minister Narendra Modi, Asia's longest bi-directional road tunnel on the Jammu-Srinagar National Highway completes the critical link connecting Kashmir with rest of India. Speaking on the occasion Modi said, “Tunnel will not only reduce the distance between Jammu and Srinagar, but will also promote tourism in the valley, open up employment opportunities for the youth and give a boost to development in the state.” J&K Chief Minister Minister Mehbooba Mufti said, "The tunnel will not just reduce the physical distance but bring Kashmir closer to the country. The inauguration of tunnels will also help to join the hearts of the people." Present on the occasion, Minister of Road Transport Nitin Gandkari, also expressed happiness at India’s longest highways tunnel being dedicated to the nation. The National Highways Authority of India has spent Rs.3,720 crore on this state-of-the-art tunnel. It took seven years to build and will link Chenani in Udhampur district with Nashri in Ramban district. The project is developed by IL&FS Transportation Networks Ltd. (ITNL).


All Weather Road

The 9 km long, twin-tube, all-weather tunnel between Udhampur and Ramban is not only India’s longest highway tunnel but also Asia’s longest bi-directional highways tunnel. Built at an elevation of 1200 metres on one of the most difficult Himalayan terrains, the tunnel will cut travel time between Jammu and Srinagar by two hours, bypassing about 41 kms of road length. It will also ensure an all weather passage on a route that often sees heavy traffic jams and disruptions due to landslides, snow, sharp curves, breakdown of vehicles and accidents. The tunnel is a part of the 286-km-long four-laning of the Jammu-Srinagar National Highway. The structure consists of a 9 km long, two-lane main tunnel with a parallel escape tunnel of same length. Both tunnels are connected by 29 cross passages at regular intervals along their entire length, which can be used for evacuation of vehicles and commuters in case of breakdown or emergencies. There are two minor bridges on the south and north sides and 4-lane approach roads with Toll Plazas at both ends of the tunnel. The maximum height permitted in the tunnel is 5 meters and for checking the height special sensors have been installed just before the toll points at both ends. The tunnel’s transverse ventilation system has inlets bringing fresh air at 8 meter intervals and exhaust outlet every 100 meters. There is also a fully-integrated control system with ventilation, communication, power supply, incident detection, SOS call box and fire fighting. Fitted with intelligent traffic mechanism, the tunnel has fully automatic smart control and no human intervention will be required for its operations. The tunnel is also equipped with advanced scanners to ward off any security threat. Very few tunnels in the world have this kind of fully integrated tunnel control. 94 percent, of over 2,000 of the workers were from J&K, and around 600 to 900 people from across India. They worked on the project in 3 shifts over the past 4 years.

The Zojila tunnel is also being built between Leh and Ladakh at a cost of Rs.6000 crores. During the year 2016-17, Rs.1019 crore have been sanctioned for 72 projects in Jammu & Kashmir.



Electrifying the tunnel

Sterling & Wilson executed electrification & cabling for the four-lane tunnel. It was involved in the design, built, turn-key solutions for electrical 11 kV substation, distribution and ancillary works of communications, power supply, incident detection, SOS call box and fire-fighting. It also designed and installed a two-tier illumination system, which will be operational around the clock for 365 days a year, with provision for variable frequency drives for ventilation systems.

Speaking on the occasion, Bikesh Ogra, President, Sterling & Wilson said, “It is indeed an honour and privilege to be part of this project. Given the scale and at times very daunting and onerous weather conditions, there were challenges in carrying out execution of works. With the valuable support of IL&FS and untiring efforts of our engineers who braved hardships and rose to ensure that this tunnel is lightened 24×7 with state-of-the-safety features, 365 days in the year. Successful completion of the project adds to our repute and repertoire, in India and abroad.”
