Prime Minister Narendra Modi will dedicate the India's longest road tunnel Chenani – Nashri Tunnel, built on the Jammu-Srinagar National Highway to the nation on Sunday. The tunnel which connects Jammu with Srinagar, will reduce travel time between the two cities by upto two hours. <br/><br/>An official release said, the tunnel is equipped with world-class security systems and is expected to boost tourism and economic activities in the state. The estimated daily fuel savings are to the tune of 27 lakhs rupees. <br/><br/>The tunnel is a single-tube bi-directional tunnel, with a 9.35 metre carriageway, and a vertical clearance of 5 metres. It also has smart features such as an Integrated traffic control system, surveillance, ventilation and broadcast systems, fire fighting system and SOS call-boxes at every 150 metres. <br/><br/>It achieves a distance-reduction of 31 kilometres, bypassing snow-bound upper reaches. Besides avoiding large scale deforestation and tree-cutting, the tunnel will provide a safe, all-weather route to commuters travelling from Jammu and Udhampur, to Ramban, Banihal and Srinagar. The project has been completed at a cost of over 2500 crore rupees.
