Q. Which among the following is the longest rail cum road bridge in India?
Answer: Bogibeel Bridge
Notes: The Bogibeel Bridge is India's longest rail-cum-road bridge, spanning 4,940 meters across the Brahmaputra River. It connects the towns of Dhemaji and Dibrugarh in the northeastern state of Assam. The bridge was inaugurated on December 25, 2018 by Prime Minister Narendra Modi. The bridge is India's first fully welded steel bridge, with no joints. It has a two-line railway track on the lower deck and a three-lane road on the top deck. The bridge is also strategically important to India, as it makes it easier to transport troops and supplies to the border with Tibet in Arunachal Pradesh.
