Commuters and transport workers endured severe suffering as a 15kilometre tailback was created on the Cumilla-Sylhet regional highway after a container trailer overturned on the important route on early Sunday.

The accident occurred at Debidwar around 6:30am when the driver reportedly lost control of the vehicle, said Parvez Ali, in-charge of Mirpur Highway Police Outpost.

On information, he said, police rushed to the scene and removed the container trailer. The vehicular movement resumed around 10:30am, he added.

Witnesses said it took hours to lift the container, during which the traffic congestion worsened, stretching up to 15 kilometres.

The situation gradually returned to normal after four hours of disruption, they said.
