The Director General of BRO said that it is important for BRO to adopt contemporary technology with the intention of expediting tunnel and bridge construction at strategic locations for the operational preparedness of the Indian Armed Forces. He said that the work of Sela tunnel in Arunachal Pradesh bordering China will be completed in May or June this year. Rajeev Chowdhary claimed that the organization has adopted 14 type of technology in the recent past for the construction of roads in the border areas. We used steel slag to build a road in Arunachal Pradesh two months ago and recently carried out a pilot with all prefabricated protective structures, reinforced earth walls, culverts, drains and footpaths fabricated at a separate site . This will help in building roads even in heavy rains in all regions (Northeast) in future, he added.
