"The highway has been restored for stranded vehicles only. Vehicles from Jammu would not be allowed to proceed towards Srinagar at the moment," a senior traffic department officer said.
The arterial road, which has been closed since Monday, was briefly re-opened for traffic on Tuesday but had to be closed again due to landslides.
The highway, the only all-weather road link connecting Kashmir valley with the rest of India was closed for traffic on Monday as Kashmir experienced the season's first major snowfall.
Divisional administration officials, however, maintained that there was adequate stock of essential commodities in the valley.
