Out of all the rivers in Assam, Brahmaputra continues to be the lifeline of Assam. The fertile plains of the mighty Brahmaputra account for almost all the human settlements that took place on its river banks. And therefore, several bridges have been built over the Brahmaputra river to make transportation easier.
As of 2022, Assam has six significant bridges over Brahmaputra River. The Minister of Road Transport and Highway (MoRTH) is yet to approve three new bridges in Assam.
This article will provide a few important points about each of these 6 bridges
The Bogibeel bridge is a 4.94 km long road/rail bridge that links Dhemaji and Dibrugarh district. Bogibeel Bridge and Dibrugarh Town only have a distance of 17 kms in between. The estimated budget for construction of Bogibeel bridge was around 5920 crores.
It was opened to the public on 25th December 2018. The Bogibeel Bridge has both a road and a railroad. It features a double line, wide gauge railroad and a three lane highway. It is built entirely of full-steel concrete composite grinders, making it the first one of it's kind in the country.
As of 2022, the Bhupen Hazarika Setu (Dhola Sadiya Bridge) is the longest bridge in India. This 3-lane bridge extends to almost 9.15 km and it is built above one of the major tributaries of Brahmaputra, the Lohit river. It was inaugurated on 26th May 2017, and connects Dhola and Sadiya.
