Here’s all you need to know about the Longest Indian Bridge Over Water: Dhola-Sadiya Bridge
The Bhupen Hazarika Setu, also known as the Dhola-Sadiya Bridge, spans the river Lohit, a tributary of the Brahmaputra.
It is an Indian beam bridge that links the north Japanese kingdom of Assam with the Indian state of Arunachal Pradesh. The bridge connects the villages of Dhola to Sadiya in the south and Sadiya in the north. The bridge has a total length of 9.15 kilometers and a width of 12.9 meters.
The bridge’s construction started in November 2011 and concluded on March 10th, 2017. It was constructed by a public-private partnership arrangement between the Ministry of Road Transport and Navayuga Engineering Engineering Company Ltd. The bridge’s total fee was Rs. 2,056 crore. It is the most well-known direction for many power challenge developers, in addition to supporting the development of several hydropower projects around the kingdom. The bridge has a three-lane highway and also serves the strategic needs of the United States in Arunachal Pradesh’s border regions.
The superstructure’s primary span is 50 meters. There are a total of 183 bridges, with one hundred and one crossing the flood plains and eighty-two crossing the river. High earthen embankments that approach the bridge from all sides are considered essential bridge components. A few more tiny bridges can also be found inside the technique embankments. The bridge’s entire width is 13.2 meters, which may be split into a 10.5-meter vehicle carriageway with a 0.9-meter footpath on both sides. For vehicle safety, there are collision restrictions on both sides.
The bridge’s superstructure is built up of segmental container structures. Externally, each container is tensioned with excessive tensile strands. The superstructure was built using asolid process, which minimizes the time gap between development cycles. As the developing system approaches the bearing level, it may be completed in a shorter time. Because the whole container period cannot be transported to the casting yard, packing containers are divided into segments, which is referred to as segmental manufacturing. Every phase’s weight is kept to a bare minimum for ease of use. Because the segments are externally tensioned, the cables flowing through the inside of the container’s internet may be prevented.
The bridge connects Assam’s Dhola with Arunachal Pradesh’s Sadiya. Previously, the most convenient way to cross the Brahmaputra was to take a boat during the day, but this became practically impossible during floods. This bridge now connects upper Assam with the southern region of Arunachal Pradesh, cutting the trip time in half from six hours to just an hour. The bridge is expected to improve India’s defense capabilities in the northeastern region by reducing the amount of time it takes to get to the India-China border.
