Launch operations along the Kathalbari-Shimulia route have been disrupted due to poor navigability through a stretch of the Padma River, leaving hundreds of vehicles stranded at the two landings.

However, speedboat operations remain unaffected.

Earlier, the authorities suspended ferry operation on the route for the same reason.

The services were halted because of navigation issues along the waterway in the morning but around 200 speedboats are on hand to transport passengers across the river, said Akhter Hossain, traffic inspector at BIWTA's Kathalbari jetty.

The disruption, however, has created a long tailback at the terminal.
