On odd-numbered highways, the number increases from north to south. In the new system, all east-west highways have odd numbers, and all north-south highways have even numbers. In 2010, the government issued a notification to rationalise the numbering system, arguing that the “existing number of National Highway does not give any indication of its location and direction”. Until 2010, National Highways continued to be numbered the way they were numbered in the National Highways Act of 1956, which listed each National Highway. What is the length of India’s road network, and of National, State Highways? The IRC is the apex body of road engineers in the country and regularly updates the technical requirements - such as width, sight distance and other related parameters - for highways and other roads. The Indian Roads Congress, a semi-official body that was set up by the government in 1934 on the basis of the Jayakar Committee’s recommendations, and registered as a society in 1937, decides the minimum requirements for roads, keeping in mind geography, speed, volume of traffic and safety. Who decides the technical requirements for different classes of roads? Village Roads connect villages to each other or to the nearest District Roads. Major District Roads (MDRs) are roads that connect areas of production, main markets and the State and National Highways crossing the state. State Highways, according to the Nagpur Plan, are the arterial roads of a state that connect to National Highways, district headquarters and important cities. Earlier in 1927, a road development committee under M R Jayakar had recommended that National Highways should be the frame on which the country’s road connectivity should rely. Roads that are required for strategic movement, those that reduce the travel time substantially, and those that open up backward areas and help economic growth, are also classified as National Highways. Under the Nagpur Plan Classification, National Highways connect all major ports, state capitals, large industrial and tourist centres, and foreign highways.
