Chenani-Nashri Tunnel: India’s Longest Road Tunnel

Now a drive through the picturesque Jammu and Kashmir valley has become a much more exciting affair with the opening of the Chenani-Nashri Tunnel. The tunnel, which is 9.2 km, is India’s longest road tunnel built in the Shivalik mountain range in the Himalayas. Also known as the Patnitop Tunnel, the tunnel connects the Kashmir Valley with Jammu.  It is Asia’s longest two-way highway tunnel.

The significance of the Tunnel

The tunnel, which is between the districts of Chenani and Nashri, was opened for vehicular traffic in April 2017. The bi-direction tunnel has reduced the distance between Jammu and Kashmir by almost 30 kilometers. The all-weather tunnel bypasses 44 avalanche and landslide-prone spots on the highway. The tunnel is part of the project for broadening of the National Highway No-44, which was the old NH1A from Jammu to Srinagar.

According to an estimate, the tunnel will save fuel of over Rs 27 lakh per day. It will provide easy connectivity for the people of Kishtwar, Bhardwah, and Doda in the Jammu region. Being an all-weather tunnel the problems of road blockage during heavy snowfall in the region has also been eliminated. The Patnitop tunnel has enabled an increase in trade and tourism in the state.


Construction of the Tunnel

The Chenani-Nashri Tunnel has been built in lower Himalayan range at the altitude of 1200 metres or 3937 feet. The foundation stone for the project was laid in June 2011, but because of the difficult terrain and technical problems, it took over 6 years to complete the project. There were landslides, heavy snowfall and even ‘demonetisation period in India’ delayed the project. The delay had caused a lot of uproar in the J&K Assembly. The construction, which is estimated to be at the cost of Rs 3.750 crore, involved nearly 1500 engineers, geologists, and numerous labourers.
