The Bhupen Hazarika Setu, also referred to as the Dhola–Sadiya Bridge is a beam bridge in India, connecting the northeast states of Assam and Arunachal Pradesh. The bridge spans the Lohit River, a major tributary of the Brahmaputra River, from the village of Dhola (Tinsukia District) in the south to Sadiya to the north. The bridge is the first permanent road connection between the northern Assam and eastern Arunachal Pradesh.
At 9.15 kilometres (5.69 mi) in length, it is the longest bridge in India. However, the New Ganga Bridge Project under construction in the Indian state of Bihar, is expected to become the longest bridge in India upon its estimated completion in December 2020, with a length of 9.8 kilometres (6.1 mi)
