The work was started in 2011 and has been inaugurated on 2 April 2017.nnIt is India’s longest road tunnel with a length of 9.28 km (5.8 mi).The original estimate to build the tunnel was ?2,520 crore (US$370 million), but escalated to a total of Rs 3,720 crore (US$550 million).The main tunnel is 13 metres in diametre, while the parallel escape tunnel is 6 metres diameter. The main and escape tunnels are connected by 29 cross passages at intervals of every 300 metres.The tunnel is equipped with SOS boxes.It is the first tunnel in the country with fully integrated tunnel system.nnThe tunnel will reduce the distance between Jammu and Srinagar by 30.11 km (18.7 mi) and cut travel time by two hours. Snowfall and avalanches in winter at Patnitop obstructs NH 44 a few times every winter and causes long queues of vehicles – sometimes for days at length. The tunnel will bypass Patnitop, Kud, and Batote and will reduce traffic jams on NH 44 in winter.
