More than 400 vehicles are stuck on both ends waiting to traverse the river.
BIWTC Aricha sector manager Mohiuddin Rasel said the fog intensified after midnight. “Visibility fell drastically around 7:30am. So, we decided to keep ferry services off to avoid accidents,” he said.
Rasel said they would resume ferry operations once the visibility improves.
