Boosting road infrastructure in the entire border belt in the Himalayan region, the Union government has decided to build a length of 4,000 km as building road infrastructure is a vital activity for securing borders and also improving the socio-economic condition of the masses in the area. The government has been focusing to boost infrastructure along Sino-India border, including the areas of dispute, following the Dokalam episode. Maintaining an all-weather road in the Upper Himalayan region was a serious concern for road construction agencies due to tough terrain, heavy snowfall, intense avalanches, sub-zero temperature, fragile geology and ecological concerns. The construction of tunnels is the only viable option to ensure all-weather connectivity and meeting ecological and environmental concerns.
