Bogibeel Bridge, recognised as India's longest combined rail and road bridge, has been constructed over which major river?

Introduction / Context:
Bogibeel Bridge is an important infrastructure project in north eastern India and is often mentioned in current affairs and geography questions. It is known for being one of India s longest rail cum road bridges, improving connectivity in Assam and Arunachal Pradesh. Understanding which river it spans helps students connect large transport projects with major rivers and regional development strategies.

Given Data / Assumptions:

- The structure in question is Bogibeel Bridge. - It is described as the longest rail and road bridge in India. - The options list four major Indian rivers: Brahmaputra, Ganga, Yamuna and Godavari. - Only one of these rivers flows through the specific location where Bogibeel Bridge is built.

Concept / Approach:
The concept involves major river systems and strategic infrastructure. The Brahmaputra River flows across Assam and is known for its wide, braided channel and frequent flooding, which makes bridge construction challenging. Bogibeel Bridge connects the north and south banks of the Brahmaputra near Dibrugarh and Dhemaji in Assam. The Ganga and Yamuna rivers are associated with northern plains and different cities, while the Godavari flows largely through central and southern India. The approach is to recall that Bogibeel is specifically linked with the Brahmaputra in Assam.

Step-by-Step Solution:

Verification / Alternative check:
Verification is simple through news articles, government press releases or atlases that mark Bogibeel Bridge across the Brahmaputra. Many exam updates emphasise that Bogibeel improves connectivity across the Brahmaputra between the southern bank at Dibrugarh and the northern bank region leading towards Arunachal Pradesh. This repeated emphasis confirms that the bridge is on the Brahmaputra, not on the other listed rivers.

Why Other Options Are Wrong:
The Ganga River does not pass through the specific region of Assam where Bogibeel is located. The Yamuna, a major tributary of the Ganga, flows mainly through northern Indian plains and is not linked to this project. The Godavari runs across central and southern states such as Maharashtra, Telangana and Andhra Pradesh and has no connection with Bogibeel Bridge. None of the above is incorrect because Brahmaputra clearly matches the official description.

Common Pitfalls:
Students sometimes rush and choose Ganga whenever a famous river is mentioned, forgetting the regional context. Another problem is mixing up different rail river bridges across the country and associating them with the wrong waterways. Paying attention to the state or region mentioned along with the project name is key to avoiding such mistakes.

Final Answer:
Bogibeel, India s longest combined rail and road bridge, has been constructed over the Brahmaputra River in Assam.
