A crack on one of the three spans of the Bhuiyangati bridge in Raiganj of Sirajgang has made the bridge sink eight inches into the ground. As a result, highway police have advised drivers of heavy vehicles to take alternative routes.
The vehicles plying on the highway - known as the lifeline of the country's northern region - have been asked to travel via Natore to reach the 11 districts.
Meanwhile, highway police have started work on alternate routes at the Hatikumrul intersection of Sirajganj and Matidali diversion at Bogura and Shakpala diversion.
Md Jahangir Hossain, superintendent of police at Bogura Region Highway Police said, "The second span out of the three that holds up the 80-meter-long bridge has been badly affected."
He added, "The bridge has sunk eight inches and is poses a risk to vehicles traveling via the bridge."
As a result, cargo vehicles from Bogura carrying more than 15 tonnes of load have been advised to travel via Natore-Banpara to reach Dhaka and other districts.
On average, one vehicle crosses the affected point of the bridge every 10 seconds.
