The Border Roads Organisation, or more famously The BRO, is a combination of Border Roads Engineering Service (BRES) officers from General Reserve Engineer Force (GREF) and officers from the Corps of Engineers (Indian Army Corps of Engineers) of the Indian Army to maintain roads that serve the borders areas of India. The organisation works for the development and maintenance of arterial roads which have strategic importance for the Indian Army. BROs activities have also helped to accelerate the economic development of the North and North Eastern (North East India) border states. The roads construction teams have to deal with some of the harshest climatic conditions in the world. The BRO faces formidable hurdles like the icy Himalayan (Himalayas) tops, the marshes of West Bengal and the deserts (Thar desert) in Rajasthan. BRO undertakes road constructions and maintenance at high altitude in the hills. Some of the BRO roads are built as high as convert6000mft0 above mean sea level.

The BRO was formed on 7 May, 1960, with the then Indian Prime Minister (Prime Minister of India) Jawaharlal Nehru as the chairman of the Border Roads Development Board, as an inter-ministerial organisation. BRO is led by the Director General of Border Roads (DGBR), as its Executive Head, who is of the rank of a Lieutenant General. The present Director General of BRO is Lt Gen Arun Kumar Nanda, AVSM, VSM. The BRO also consists of a General Reserve Engineer Force (GREF), the execution force, under the Ministry of Surface Transport.
