The landslide was triggered by heavy rains in the wee hours, blocking Dhar-Udhampur road at Moda Dadda, about 18-kms from here, Traffic Police officials said.
Dhar road is considered as the shortest route to the valley and is preferred by truckers instead of going via Jammu.
A senior officer of Beacon, who was present at the landslide site, said 40 labourers had been engaged to clear the landslide debris.
Specialised machines were also awaited from Samba and Batote areas, he said.
