The BP Highway has been closed for eight hours after the flooded Roshi stream swept away diversion on Monday night.
The diversion at Mapti was eroded by the flooded river, resulting in the complete halt in vehicular movement, according to the District Police Office.
Efforts are underway to resume the highway, the Office said.
Information Officer at the District Police Office Min Bahadur Ghale said that the road section towards Mangaltar from Roshi Rural Municipality-12 was damaged by the flood.
The police team and locals have been working together to open the road for one-way traffic. A total of 17 passengers were stranded after the vehicular disruption. They were rescued by the local police.
Diversion was constructed at the place where the BP Highway had suffered severe damages in the last September floods.
Meanwhile, search for a woman missing in the flood since Monday afternoon is underway.
Renuka Giri (33) of Subbagaon of Panauti Municipality-5 had gone missing at 6 pm Monday. She was swept away by the flooded Dhalmale rivulet while returning home from a festival.
The police had halted the search for the woman after midnight, which resumed early this morning.
Deputy Superintendent of Police Ghale further informed that a joint team of Nepal Police, Nepal Army and the Armed Police Force was mobilized to search for the missing woman.
The sudden rainfall in the Panauti Bus Park area had inundated the vicinity.
