Chenani-Nashri Tunnel, also known as Patnitop Tunnel, is a road tunnel in the Indian state of Jammu and Kashmir on NH 44 (former name NH 1A before renumbering of all national highways). The work was started in 2011 and has been inaugurated on 2 April 2017 by Prime minister Sh. Narendra Modi.
It is India's longest road tunnel with a length of 9.28 km (5.8 mi). It is the first tunnel in the country with a fully integrated tunnel control system. The tunnel reduces the distance between Jammu and Srinagar by 30 km and cut travel time by two hours. The all-weather tunnel bypasses snowfall and avalanche prone areas in winter at places like Patnitop, Kud, and Batote that obstruct NH 44 every winter and cause long queues of vehicles - sometimes for days at length.
The tunnel is located on the lower Himalayan range at an altitude of 1,200 metres. The Southern portal (end) of the tunnel is at 33°02′47″N 75°16′45″E / 33.0463°N 75.2793°E and the Northern portal (end) of the tunnel is at coordinates 33°07′43″N 75°17′34″E / 33.1285°N 75.2928°E. The tunnel has been excavated starting from about 2 km (1 mi) from Chenani town south of Patnitop to Nashri village north of Patnitop.
