The old Mawa ferry terminal has been shifted to Shimulia to facilitate the construction of Padma Bridge.
Kewrakandi terminal’s Assistant Manager Habibur Rahman said they had shut the route at around 9:30pm as visibility was alarmingly low.
Senior Terminal Super Habibul Islam said it had become hard even to see objects as far as a metre away.
“We’ve closed the route to avoid accidents,” he said.
The stranded ferries anchored mid-river and will start for their destinations once the fog cleared, Islam added.
Four other ferries have been anchored at both ends of the route.
Tuesday’s river traffic suspension was the first of this season.
Several thousand vehicles have been stranded on both ends of the Shimulia-Kewrakandi route that connects Dhaka with 21 south-western districts.
