Overview of the project
The road and railway crossing across the Brahmaputra on National Highway-52B is located at Bogibeel, about 17km downstream of Dibrugarh in Assam. The location is an area of high intensity rainfall (the annual rainfall ranges from 2,300 mm to 3,800 mm). During heavy rains, the surface runoff along the embankment slopes erodes the surface soil, forming rills and gullies down the slope, which widen with more runoffs. The government of India has given this project utmost importance, declaring it a national project in 2007. This bridge is India’s longest Rail–cum–Road bridge spanning 4.95 kms, and a vital link between Assam and Arunachal Pradesh.
