The Jammu-Srinagar National Highway remained closed for the third day on Thursday as fresh snowfall is hampering efforts of authorities to clear the road for vehicular movement.
The arterial road was closed on Tuesday after a snow avalanche blocked both tubes of the Jawahar Tunnel on Qazigund side.
The official said intermitted snowfall was hampering road clearance operations.
"The Jammu-Srinagar Highway is still closed for traffic. Efforts are on to make the road traffic worthy at the earliest," an official of the traffic department told PTI.
Intermittent snowfall has been experienced in the rest of the valley also since Thursday morning, a MET department official said.
Meanwhile, the cold wave conditions intensified in Kashmir as the minimum temperature at most places witnessed a drop last night.
