Bridges of Assam Over the Brahmaputra River

An Insightful Article by Smart Study Academy

Introduction

The Brahmaputra River, one of Asia’s most powerful rivers, flows through the heart of Assam, shaping its geography, economy, and culture. While it is a source of life, it also poses significant barriers to connectivity. Over the years, several iconic bridges have been built across the Brahmaputra, linking the north and south banks and paving the way for growth and integration. This article by Smart Study Academy explores the major bridges over the Brahmaputra in Assam, their significance, challenges, and future prospects.
