India’s longest rail-cum-road bridge “Bogibeel” is built over which river? 

The Bogibeel bridge is India’s longest rail-cum road bridge. The 4,940-metres long bridge situated on the Brahmaputra river is the country’s first fully welded steel bridge with no joints. Sited about 17 km downstream of Dibrugarh town, the 4.94km bridge will facilitate road and rail connectivity between the north and south banks of the Brahmaputra in the eastern part of Assam and Arunachal Pradesh. The bridge is 32m above the water level of the Brahmaputra and is fashioned on a bridge that links Sweden and Denmark.
