A culvert on the Nimgachi-Heutnagar road in Dhunat upazila of Bogura district suddenly collapsed on Monday morning following continuous rainfall. The incident caused no casualties but severed road communication for about 30,000 residents across at least 15 villages in Nimgachi and Kalerpara unions. The collapse occurred when soil beside the structure eroded under heavy water pressure during drainage from nearby fields.

According to local sources, the 15-meter-long culvert was built in 2001 under the Annual Development Programme to improve rural communication and water drainage. Residents alleged that substandard construction made the culvert unstable from the beginning, and no repairs were undertaken despite its risky condition. Continuous rain and poor maintenance ultimately led to its failure, forcing locals, students, and workers to take longer alternative routes.

Local Government Engineering Department (LGED) engineer Bakhtiar Hossain said a proposal for a new culvert has been prepared and sent to higher authorities. The upazila administration also instructed immediate measures to restore communication and later build a durable bridge at the site.
