Transport system in Nepal is very poorly developed. Though several factors are involved in it, irregular mountainous terrain accompanied by landlocked location is the major physical constraints affecting the balanced development of transport network in Nepal. This weakness in transport has seriously hampered the speedy development of social-economic life of the country. At present there are 5950km roadways, 43 airports, 61km railways and 42km. Ropeways in the country. All the railways and most of the roadways are concentrated in the tarai region. Airports are scattered over hills and tarai belt. The Tribhuvan airport located just on the east of Kathmandu City is the International airport. Being a landlocked mountainous country, water transport is virtually nonexistent. In general, transport facility diminishes towards far north and Far West of the country.
