A bridge on the Mumbai-Goa highway linking Mahad and Poladpur collapsed in Ragad district in Konkan due to heavy rains in the early hours on Wednesday. Approximately 80 per cent of the bridge had collapsed. The collapse is likely to have been caused by the overflowing of Savitri river in Mahabaleshwar. No casualties have been reported yet but according to the Raigad District Collector, two buses that left Ratnagiri are missing. NDRF teams have been deployed at the site. There are chances that the vehicles must have fallen into Savitri river. Maharashtra CM Devendra Fadnavis soon rushed to the site after the bridge collapsed. Many officials from the administration have rushed to spot as the rescue measures are on-going. The Metereological Department had warned of heavy to very rainfall in Nashik in north Mahararashtra and coastal areas from Raigad to Sindhurdurg in Konkan over the next 24 hours.
