"The highway has been closed for vehicular traffic because of snowfall in Bannihal. It is snowing at this time too. Road clearance operation would start once snowfall stops," an official said.
Reports said many vehicles carrying passengers and goods have been stranded on the highway.
The Srinagar-Jammu highway is the landlocked valley's only road link to the rest of the country. All essential supplies are routed to Kashmir through this highway. Temporary closures of the highway invariably result in unscrupulous traders resorting to hoarding and profiteering.
The weather department has forecast widespread rain and snowfall in the valley on Monday which isset to continue till February 7.
An adverse weather advisory issued by Sonam Lotus, director of the local MET office, had said last week that heavy to very snowfall, especially in the Pir Panjal Mountain Range in the valley, could disrupt air and surface transport.
