Chenani Nashri Tunnel
India’s longest road tunnel is being constructed in Jammu& Kashmir near Chenani, a small town in Udhampur district. The tunnel will be 9.2 kms long and will help to make travel between Jammu and Srinagar shorter and easier.
Travelling by road from Jammu to Srinagar is arduous and takes very long. Moreover, in winter NH 1A, which is the life line that connects Jammu & Kashmir with the rest of the country, becomes clogged with traffic jams due to heavy snowfall or landslides. The Chenani-Nashri tunnel was planned with the purpose of reducing traffic jams on the National Highway NH 1A especially in winter and also reducing the distance between Jammu and Srinagar. The tunnel is a key section of a basic road improvement scheme of NH 1A which links the Kashmir Valley with the rest of India.
When the Chanani- Nushri tunnel will become functional, traffic in Patnitop through which the National highway passes will be greatly reduced as the tunnel will cause the National Highway to by-pass the town.
The tunnel will reduce the distance between Jammu and Srinagar by 31 kms and also decrease travel time by nearly two hours. The much awaited tunnel will provide a safe and all-weather route for travel between Jammu and Srinagar.
The construction of the 9.2 Kms long Chenani-Nashri tunnel commenced in 2010 and is scheduled to be complete by 2016. The tunnel starts about 2 kms from the town of Patnitop and will decongest traffic in the town as the NH 1A will bypass the town.
Almost half of the excavation work of the tunnel was completed by 2012 and the excavation work was completed by July 2015. The work of lining of the tunnel and laying the road etc. is expected to be completed by the end of 2016.
Chenani-Nashri tunnel is located in the middle Himalayas at an elevation of 1200m. It has an overburden of up to 1km. The excavation work of the tunnel was undertaken by IL&FS Transportation Networks Ltd and was completed in record time of less than 4 years. Latest technology that was apt for the project; New Austrian Tunnelling Method or NATM technique of excavation and support was used sequentially. There will be two carriage lanes in the tunnel which will have a diameter of 13 metres. The cost of the project is estimated to be Rs. 3720crores.
As the road tunnel is very long, precautions had to be planned and will be implemented to ensure smooth and safe travel through the tunnel.
Chenani-Nashri Tunnel will be the first tunnel in India which will have the latest and the most advanced Integrated Tunnel Control System (ITCS). This system ensures that the tunnel is equipped with proper ventilation, fire control, signal system, communication system and emergency electrical systems toiling that will be automatically activated when needed.
A smaller escape tunnel is also being built parallel to the main tunnel so that emergency services can reach inside the tunnel and smoke and/or persons can be removed in case there is an accident or fire inside the tunnel.
As the town of Chenani is only 2 kms away from one extremity of the tunnel, an emergency 100 bed hospital is being built to treat accident victims.
IL&FS Transportation Networks commenced the project in August 2011.
The excavation process was completed in July 2015.
The breakthrough ceremony of the Chenani Nashri Tunnel took place on July 13, 2015.
The completion date of the project is expected to be May 2016 and the tunnel will be open for traffic by July 2016 according to National Highway Authority of India Project Director R P Singh.
Last week, he had said that the tunnel on Jammu-Srinagar National Highway will be completed by July, 2016.
