Amid a festive rush, more than 55,000 vehicles entered Shimla in the past couple of days for Christmas weekend. Massive traffic jams were witnessed in Shimla, Manali and Kasol, with huge congestion of vehicles. About 55,000 vehicles crossed the Atal tunnel in Rohtang - that joins Kullu and Lahaul and Spiti - in the past three days, officials said.
Several videos have surfaced on social media showing a long queue of vehicles on roads.
