The Bogibeel Bridge, is the country's longest rail-cum-road bridge, built over the Brahmaputra river at Bogibeel, near Dibrugarh in Assam.
The Bogibeel Bridge, which was a part of the Assam Accord and sanctioned in 1997-98, is likely to play a crucial role in defence movement along the India-China border in Arunachal Pradesh.
"The PM will inaugurate the bridge on December 25 which is also marked by the government as Good Governance Day," the official told.
The 4.94 km bridge, work on which started in 2002, is the longest rail-cum-road bridge in India. It will connect Dhemaji and Dibrugarh districts at the north and south banks of Brahmaputra river.
