Two India-funded bridges open on Bhutan's Trashigang highway
The Revidrang and Rolong bridges replace weak, cracked old bridges and were built for Nu. 76 million under Indian project-tied assistance.
Two bridges built with Indian funding, the Revidrang and Rolong bridges on Bhutan's primary national highway to Trashigang, were inaugurated on 12 November 2026 by India's Ambassador to Bhutan, Sandeep Arya, and the Dasho Dzongda of Trashigang, the Tripura Chronicle reported.
Key facts
- Built by Shamballa Infra Pvt. Ltd. at a total cost of Nu. 76 million.
- Funded by the Government of India under Project Tied Assistance.
- The old Rolong bridge had a limited load-carrying capacity and a narrow carriageway.
- The old Revidrang bridge had been closed because of significant cracks in its superstructure.
- Bhutan's Department of Surface Transport says connectivity along the highway to Trashigang will improve.
The engineering angle
Replacing a bridge on the only highway to a district is harder than building a new one. Traffic has to keep moving on a diversion, and in hill terrain there is little flat ground for one. Bridges in eastern Bhutan also deal with steep streams, heavy monsoon flows and debris, so scour protection and enough waterway matter as much as the deck.
