The vehicular traffic on 300 km long Jammu-Srinagar national highway has been closed due to landslide at Hingni in Ramsu today. According to the Traffic Police sources, a big landslide and boulders suddenly rolled down on the road this morning thereby halting hundreds of Jammu bound vehicles which were part of the scheduled one way down traffic (Srinagar to Jammu) today. However, the concerned agencies immediately pressed into service men and machinery to clear the debris from the road and efforts are on to  make the traffic worthy by today evening. <br />
