Indian Roadways

A good road network is a critical infrastructure requirement for rapid growth. It provides connectivity to remote areas; provides accessibility to markets, schools, and hospitals; and opens up backward regions to trade and investment. Roads also play an important role in inter-modal transport development, establishing links with airports, railway stations, and ports.

India has the second largest road network in the world with a total length of 46.90 Lakh kilometres. The road network can be broadly classified into five broad categories viz. Expressway; National Highways (NHs); State Highways (SHs); Other & rural roads. Out of this, only 1 Lakh kms comes under National Highways and 1.60 Lakh kms under state highways. Rest are ‘other’ roads. Thus, only 2% of road length in India is covered under National Highways. Currently, around 1200 kilometres length is covered by express highways, highest category of roads in the Indian road network.
