India has one of the largest road networks in the world, aggregating to about 2.3 million km at present. In India, roadways have preceded railways. They still have an edge over railways in view of the ease with which they can be built and maintained.
IMPORTANCE OF ROAD TRANSPORT VIS-A-VIS RAIL TRANSPORT:
In India, roads are classified in the following six classes according to their capacity.
The government has launched a major road development project linking Delhi-Kolkata- Chennai-Mumbai and Delhi by six-lane Super Highways. The North-South corridors linking Srinagar (Jammu & Kashmir) and Kanyakumari (Tamil Nadu), and East-West Corridor connecting Silcher (Assam) and Porbander (Gujarat) are part of this project. The major objective of these Super Highways is to reduce the time and distance between the mega cities of India. These highway projects are being implemented by the National Highway Authority of India (NHAI).

Delhi-Jaipur Highway
National Highways link extreme parts of the country. These are the primary road systems and are laid and maintained by the Central Public Works Department (CPWD). A number of major National Highways run in North-South and East-West directions.

Roads linking a state capital with different district headquarters are known as State Highways. These roads are constructed and maintained by the State Public Works Department (PWD) in State and Union Territories.
These roads connect the district headquarters with other places of the district. These roads are maintained by the Zila Parishad.
Border Road Organisation a Government of India undertaking constrructs and maintains roads in the bordering areas of the country. This organisation was established in 1960 for the development of roads of strategic importance in the northern and north-eastem border areas. These roads have improved accessibility in areas of difficult terrain and have helped in the economic development of these areas.
The another classification can be done on the basis of type of material used for building roads.

The length of road per 100 sq. km of area is known as density of roads. Distribution of road is not uniform in the country. Density of all roads varies from only 10 km in Jammu & Kashmir to 375 km in Kerala with the national average of 75 km (1996-97).
