The Bhupen Hazarika Setu is a bridge that connects ________.

The correct answer is Assam with Arunachal Pradesh . Key Points The Bhupen Hazarika Setu , also popularly known as the Dhola-Sadiya Bridge , is a beam bridge in India that spans the Lohit River , a major tributary of the Brahmaputra River . It connects the village of Dhola in the Tinsukia district of Assam with the town of Sadiya , which provides easy access to the Lower Dibang Valley in Arunachal Pradesh . The bridge was inaugurated on May 26, 2017 , by Prime Minister Narendra Modi , and it significantly reduced the travel distance between these two North-Eastern states by approximately 165 kilometers . Stretching a total length of 9.15 kilometers , it holds the distinction of being the longest bridge in India over water, surpassing the Bandra-Worli Sea Link . The structure is strategically vital as it facilitates the rapid movement of Indian Army tanks and heavy artillery toward the Line of Actual Control (LAC) on the border with China . Additional Information Naming and Significance : The bridge is named after Dr. Bhupen Hazarika , an iconic singer, lyricist, and filmmaker from Assam who was posthumously awarded the Bharat Ratna in 2019. Before the construction of this bridge, the only way to cross the Lohit River at this point was via ferry services , which were often suspended during the monsoon season due to flooding. The project was executed under the Ministry of Road Transport and Highways and was built to withstand the weight of 60-tonne battle tanks like the Arjun and T-72 . The construction was a joint venture between the Navayuga Engineering Company Ltd and the National Highway and Infrastructure Development Corporation Ltd (NHIDCL) .
