“Hon’ble PM Narendra Modi will inaugurate India’s longest Highway tunnel on NH-44 at Jammu and Kashmir on April 2, 2017,” said Gadkari in a tweet.
The tunnel — Chenani-Nashri Tunnel and also as Patnitop Tunnel — has a length of 9.2 km (5.7 mile).
Modi will also address a public rally after the dedication of the tunnel project to the nation.
The work on the longest tunnel started on May 23, 2011 in the lower Himalayan mountain range and cost Rs 3,720 crore, officials said.
It is located at an elevation of 1,200 metres and is the first to have world-class “integrated tunnel control system”.
