Lt Gen Rajeev Chaudhary, Director General, Border Roads Organisation (BRO), after having already spearheaded some of the organisation's remarkable feats like successfully completing the ‘World’s highest motorable road’ and ‘World’s longest highway tunnel’, has now secured another impressive achievement. Under Chaudhary’s leadership, BRO has now taken up the ambitious project which will give India its first underwater tunnel. The underwater road-cum-rail tunnels have been planned by the Railway and the Road Transport Ministries and are to be located in Assam across the Brahmaputra river at an estimated cost of  Rs.70 billion. Three tunnels will be made in the project, out of which one will be for roadways, second for railways and third for emergency purposes.
