The centre government is working on a project of building 699-km long roads in areas bordering Bhutan and in this connection a detailed project report has been prepared and sent to environment ministry. The China shares border with four Indian states including Assam (267 km), Arunachal Pradesh (217 km), West Bengal (183 km) and Sikkim (32 km) and government has proposed all-weather border road network all along the frontier with Bhutan and the move has been aimed at effective border guarding. As the proposed border road will run through the northern fringe of the Manas National Park and Bornadi Wildlife Sanctuary, the Ministry of Environment is contemplating clearing the proposal. Located in the Himalayan foothills, Manas National Park is listed in UNESCO's World Heritage site and is contiguous with the Royal Manas National Park in Bhutan.
