These roads constitute the main arteries of transport in the country and are also of military importance. These roads are selected in such a manner that they afford uninterrupted road communication through the country. These National Highways should have carriageway of at least two-lane width i.e., of 8 m width. These should have a modern type of surfacing. The responsibility of construction and maintenance of these highways lies with the Central Government.
