Nepal is a landlocked country with China to the North and India to the South. Road is the major transportation modes and aviation supports few part of the country due to difficult geographical feature. Though transportation through railway is possible and various plans has been made in the past, it is not been utilized yet. The road density in Nepal is lowest at 121 km per 1000 sq km of land area compared to other South Asian Countries. The total road network in the country consisted of 64,500 km. More than 60 percent of the road network is concentrated in the lowland (Terai) areas of the country. Out of the total 77 districts in country,75 have access to all weather roads and 2 districts in the country (Dolpa and Humla) still remained unconnected through roads. The network density is low, at 14 kms per 100 km2 and 0.9 km per 1,000 people. A Department of Roads (DoR’s) survey shows that 50% of the population of the hill areas still must walk two hours to reac.
