India’s longest road tunnel, connecting Cheneni and Nashiri towns on the new Jammu-Srinagar National Highway, has successfully completed its trial run. The 9.2 km long twin tube is expected to be opened for public usage by the end of March 2017.

Speaking on its opening, J S Rathore, the Project Director of the Chenani Nashiri Tunnelway stated that the tunnel would be formally thrown open to regular traffic after inauguration by Prime Minister Narendra Modi, which is expected to happen soon.  Rathore added that the road tunnel would help in reducing the traffic jams on National Highway-1A that occur due to snowfall and avalanches in winter.
