The Border Roads Organisation (BRO) maintains roads that serve the borders areas of India. It is staffed with a combination of Border Roads Engineering Service officers from the General Reserve Engineer Force (GREF) and officers from the Corps of Engineers of the Indian Army. The organisation develops and maintains arterial roads on the borders of India. The BRO is also involved in the construction of a tunnel at the Rohtang pass. BRO's activities have also helped to accelerate the economic development of the North and North-Eastern border states of India. The road-construction teams have to deal with harsh climatic conditions.
The BRO faces environments like the icy Himalayan mountaintops, the marshes of West Bengal, and the deserts in Rajasthan.
