Brahmaputra Infrastructure Limited has successfully completed the construction and testing of the Tall Bridge at km 42.36 on the new Broad Gauge railway line from Bhairabi to Sairang. Executed in a joint venture with a contract value of ₹116.59 crore, this achievement marks a significant milestone in the development of one of Northeast India’s most ambitious infrastructure projects.
The Tall Bridge, officially numbered 161–162–163, stands as a remarkable feat of engineering on the Bhairabi–Sairang route. Built as a steel girder bridge, it comprises multiple spans, including two sections of nearly 48 meters and seven spans of 78.8 meters each. The project involved extensive piling and foundation work, erection of steel girders across all spans, concreting, reinforcement, alignment, installation of utilities and safety features, and the implementation of comprehensive protection measures to ensure long-term structural integrity.
The testing process was carried out with precision in line with prescribed engineering standards and safety protocols. It included rigorous load testing, structural strength assessments, and detailed alignment verification, followed by speed trials reaching up to 110 km per hour. After completing the trials, the Commissioner of Railway Safety cleared the bridge for operations at a maximum permissible speed of 90 km per hour, confirming that the structure is safe, reliable, and ready for integration into the railway network.
The completion of this project is a significant step forward for the Bhairabi–Sairang railway line, which has been designed to transform connectivity in the region. By linking previously inaccessible areas, the project is expected to drive economic development, strengthen regional integration, and create new opportunities for growth. The Tall Bridge in particular stands as a symbol of Brahmaputra Infrastructure’s technical capability, dedication to quality standards, and timely execution of large-scale projects.
Adding to its importance, the new railway line, along with the iconic Tall Bridge, is set to be inaugurated by the Hon’ble Prime Minister of India, Narendra Modi. Once operational, the Bhairabi–Sairang line will not only revolutionize transportation across the region but will also act as a catalyst for trade, mobility, and socio-economic development in Northeast India.
