Dense fog disrupted smooth ferry operations on the key Patutia-Daulatdia route on early Saturday.
The authorities suspended ferry services several times between 3:00am and 7:00am due to poor visibility, said Assistant General Manager (AGM) Zillur Rahman of Bangladesh Inland Water Transport Authority.
Several hundred vehicles remained stranded on both sides, according to a news agency report.
However, the ferry service resumed around 7:00am after visibility improved, the official said.
