The Vijayawada-Hyderabad highway is again full of heavy traffic, as city-dwellers, who had gone to their native places to celebrate Sankranthri are returning. All toll plazas have been alert since last night, what with queues of cars and vehicles returning to Hyderabad. Toll plazas in Nalgonda and Warangal too are jampacked with long stretches of vehicles. Extra security arrangements have been made on the occasion. As the traffic is likely to increase by evening, more security personnel will be posted at the toll gates.
