Project Deepak of the Border Roads Organisation (BRO) celebrated its 66th Raising Day at Shimla in Himachal Pradesh, marking over six decades of service in the strategically important Western Himalayas. The event underscored the project's long standing role in maintaining and developing critical infrastructure in difficult terrain. The celebration reflected continued emphasis on connectivity and support to communities in remote border regions. Project Deepak's area of responsibility covers key districts including Shimla, Kinnaur, Kullu and Lahaul-Spiti, and it has been at the forefront of constructing and upgrading vital routes. The project was involved in the historic Hindustan-Tibet Road and in building key stretches of the Manali-Leh axis, work that has supported civilian access and strategic movement. These efforts have contributed to regional development while strengthening lines of communication. In addition to road construction and maintenance, the project has been active in disaster management and humanitarian assistance, undertaking numerous rescue operations during natural calamities. In May 2023 BRO teams rescued around 300 stranded motorists at Baralacha La pass, and in July 2023 over 250 civilians were evacuated from Chandrataal in a challenging high altitude operation. Such missions have demonstrated the organisation's capacity to respond under severe conditions. Raised in 1961, the project is entrusted with over 1,100 kilometre (km) of road network, including critical high altitude and border roads, and it continues to play a crucial role in defence preparedness. The unit consistently supports the armed forces by maintaining vital lines of communication and ensuring operational readiness in high altitude areas. The milestone anniversary highlighted the sustained contribution of Project Deepak to national security and to communities across the region. The project also engages with local stakeholders to improve access to services and to foster sustainable development in fragile mountain ecosystems.
