Opeshwar/Dehradun: A Bailey bridge over the Tamak drain connecting Uttarakhand’s Niti Valley was washed away by floodwaters on Monday evening, snapping road connectivity to around a dozen villages and the border area, while a Border Roads Organisation (BRO) driver went missing after being swept away by the strong current, officials said. The bridge, located on the Malari-Niti National Highway connecting Jyotirmath (Joshimath) with the border area, was washed away following a sudden rise in the water level of the Tamak drain, Chamoli District Disaster Management Officer N K Joshi told PTI. A vehicle was also swept away in the flooded drain, officials said. Jyotirmath Tehsildar Mahendra Arya said BRO driver Pankaj, a resident of Pithoragarh district, was swept away after the bridge suddenly collapsed while he was observing the floodwaters. For the past several years, the Joshimath-Niti road has been disrupted by floods and landslides in the Tamak drain.
