The 270-km highway was closed on January 21 following heavy snowfall.

In a major relief to stranded passengers, the authorities Sunday allowed Srinagar-bound light motor vehicles (LMV) to ply from Jammu as the strategic Jammu-Srinagar national highway was reopened partially for traffic after six days, a senior police officer said.

A fresh landslide struck the highway near Anokhi fall Sunday morning but men and machinery are on the ground and hopefully the traffic which was allowed from Jammu to Srinagar will be cleared, Inspector General of police, Traffic, Alok Kumar told PTI.

The 270-km highway, the only all weather road linking Kashmir with rest of the country, was closed on January 21 following heavy snowfall in the Jawahar Tunnel area -- the gateway to Kashmir -- and multiple landslides triggered by the incessant rains between Banihal and Ramban over the past week.

A massive avalanche had also struck the highway on Tuesday last, blocking both tubes of the Jawahar Tunnel on Qazigund side but the Border Roads Organisation (BRO), which maintains the stretch of the highway, cleared the road for traffic, Mr Kumar said.

Inclement weather hampered the early reopening of the road, leaving hundreds of vehicles, mostly trucks, stranded.

The stranded passengers held demonstrations in Jammu and Udhampur over the past couple of days against the administration for its alleged failure to make necessary arrangements for their stay and were demanding their airlifting to Srinagar as was the practice in the past during such situations.

"After reviewing the situation on the ground, the LMVs were cleared from Jammu to Srinagar Sunday morning," the police officer said.

He said efforts are on to clear the debris at the scene of the landslide to allow smooth passage of the cars and vans and also to make it traffic worthy for heavy vehicles as well.

Meanwhile, the night temperature in most parts of the Jammu division marked an improvement with the city recording a low of 4.1 degrees Celsius compared to the previous night''s 3.7 degrees Celsius.

The snow-bound Bhaderwah town in Doda district was the coldest recorded place in the region with a low of minus 3.4 degrees Celsius, a spokesman of the MET department said.

He said the night temperature appreciated by over three degrees in Banihal town, which recorded a low of minus 2.5 degrees Celsius compared to previous night''s minus 6.2 degrees Celsius.

Katra, the base camp for pilgrims visiting Vaishno Devi Shrine, recorded a low of 3.8 degrees Celsius, the spokesman said.
