In Mangaluru a 150-metre bridge collapsed over Phalguni river around two days ago. The authorities have barricaded the particular place and the police are ensuring there is no movement by people around the bridge. As per Mirror Now correspondent's report, this particular bridge was built around 30 to 35 years ago. Fortunately, there were no casualties when the bridge collapsed, however, the incident occurred right after a bus crossed the bridge on the day of the accident. There are many theories about the reason behind the collapsing of the bridge. Locals of the Mangaluru taluk say that it could have fallen down perhaps because of alleged sand mafia working in the area. The Public Works Department officials are also being questioned on the quality of material used for the construction work of this particular bridge. A Public Works Department Engineer said that all of the sudden the entire bridge collapsed within few minutes, while no cracks or ratting sounds preceded the collapse which was shocking for him. The bridge is very instrumental to connect from Mangaluru to Bantwal district because of which the citizens are facing serious commuting issues in the area. The police right now will ensure that along with the Municipal body of the city, they clear this bridge and route another pathway for regular usage. A temporary diverted route has been established by the authorities for the daily commuters to ensure they can connect to the other side of the bridge as well.As per a report in The Hindu, it is alleged that the course of river Phalguni has diverted largely after the construction of a vented dam on the upstream at Siddakatte. The bridge was built with a stone foundation and is about 150 metres long while it has six spans.
