The Northeast Frontier Railway (NFR) continues to make remarkable progress in enhancing safety and connectivity across its zone through the construction of Road Over Bridges (ROBs). As part of this sustained effort, NFR successfully completed construction of 11 ROBs during FY 2024–25 over its divisions, reinforcing its commitment towards replacing level crossings gates (LC gates) with modern, grade-separated structures. These ROBs not only eliminate the risk of accidents at level crossings but also significantly reduce traffic congestion, improve punctuality of trains and offer uninterrupted movement for road users. With the pace of infrastructure modernization gaining momentum, such projects are playing a pivotal role in transforming transportation networks across the Northeast.
A standout example of this progress is the recently completed Mancotta Road Over Bridge (ROB) in Dibrugarh, Assam. Located at a critical busy junction connecting Thana Chariali to Chowkidinghee, the new ROB replaces an aging 1965-built structure to accommodate the growing urban traffic and facilitate Indian Railways’ electrification initiative. Designed with a vertical clearance of 6.55 metres, the bridge ensures safe passage of electrified trains while enabling smooth vehicular movement above. The ROB spans 450 metres with five 30-metre composite girders and 150 metres of approach road on either side, complemented by a 7.5-metre wide dual-lane carriageway and 1.5-metre footpaths on both sides for pedestrian safety.
The Rs. 60.13 Cr. project, executed by IRCON International Ltd., was funded entirely by NFR and constructed over 1.2-metre diameter piles driven to 32-metre depth. With enhanced features such as high parapet walls and dedicated street lighting, the bridge offers safety and functionality in all seasons. The Mancotta ROB is more than an infrastructure upgrade. It is a vital enabler of electric traction at Dibrugarh Town station and a symbol of forward-thinking urban planning. As NFR continues to replace old level crossings with durable and efficient ROBs, it is actively laying the foundation for a safer, faster, and more sustainable future for the Northeast.
