India's Longest River Bridge Nears Completion
7 May
Summary
- India's longest river bridge, Dhubri-Phulbari, aims for September 2028 completion.
- The bridge will cut journey time from 3 hours to just 20 minutes.
- It connects Assam and Meghalaya, enhancing trade and connectivity.
The Dhubri-Phulbari Bridge, poised to become India's longest river bridge at 19.28 kilometers, is targeted for completion in September 2028. This ambitious project, developed by NHIDCL with loan assistance from the Japan International Cooperation Agency, carries an estimated outlay of Rs 4,997 crore.
The bridge will span the Brahmaputra River, connecting Dhubri in Assam and Phulbari in Meghalaya, forming a crucial part of National Highway 127B. It features 12.62 kilometers of extradosed cable-stayed spans and accompanying viaducts and approach roads, configured for four lanes.
This structure represents a significant upgrade from the current travel options. A ferry crossing takes up to three hours and is often disrupted by weather, while a road detour exceeds five hours and covers 205 kilometers. The new bridge will reduce this journey to approximately 20 minutes, year-round.
Engineers faced considerable challenges constructing across the Brahmaputra due to its fluctuating water levels, unstable soil conditions, and seismic activity. The design incorporates robust foundations and advanced structural systems to mitigate these risks.
Beyond local benefits, the bridge is expected to bolster international trade, serving as a corridor connecting domestic markets to Nepal, Bhutan, and Bangladesh. It will enhance the region's logistical performance and competitiveness as a transit hub.
