The document discusses the classification of roads according to location, importance, traffic, and tonnage. Roads are classified based on whether they are national highways, state highways, major district roads, other district roads, or village roads. They are also classified into categories based on the importance of connecting stations, holy places, and historical places. Additionally, roads are classified by traffic carried per day and tonnage carried per day. The document concludes by mentioning the organization of state highway departments.

- 3. CLASSIFICATION OF ROADS Roads are classified into different categories as under: • According to location • According to importance • According to traffic • According to tonnage Highway Engineering:Introduction:2
- 4. Classification of roads according to location 1. National Highways (NH) 2. State Highways (SH) 3. Major District Roads (MDR) 4. Other District Roads (ODR) 5. Village Roads (VR) Highway Engineering:Introduction:2
- 5. National Highways The main highways running through the length and breadth of the country connecting major ports, foreign highways and capital of states are called national Highways. Highway Engineering:Introduction:2
- 6. National Highways Main arteries of transport in the country. Military importance Carriageway of at least two lane width. Latest Surfacing Construction and maintenance by central govt. Highway Engineering:Introduction:2
- 8. State Highways The highways linking district headquarters and important cities within the state or connecting them with NH’s or highways of the neighbouring states. Highway Engineering:Introduction:2
- 9. State Highways Also called Provincial Highways. Serve as arterial routes of traffic to and from district roads within the state. Preferably be of two lane width. Should have modern type of surfacing. Construction and maintenance is looked after by state govt. Highway Engineering:Introduction:2
- 10. Major District Roads • Important roads within a district . • Serving areas of production and markets and connecting these places with each other or with the National highway. • Should have at least single lane metalled road. • Responsibility of construction and maintenance lies with the district authorities. Highway Engineering:Introduction:2
- 11. Other district Roads Roads serving rural areas of production and providing them with outlet to market centres, Tehsil headquarters and railway stations. These roads have lower specifications than MDR’s. Should have single lane width of at least stabilized soil, gravel or water bound macadam surface. Highway Engineering:Introduction:2
- 12. Village Roads Roads connecting villages or group of villages with each other or with the nearest ODR’s. Very important from the rural area development point of view. Un-metalled roads and have single lane width of stabilized soil or gravel. Construction and maintenance responsibility is of local district authorities. Highway Engineering:Introduction:2
- 13. Classifiation of Roads according to Importance According to the importance of stations of strategic importance, holy places , historical places, roads are classified into three categories: Class I Roads Class II Roads Class III Roads Highway Engineering:Introduction:2
- 14. Classification of roads according to traffic 1. Very heavy traffic roads (Carrying > 600 vehicles/day) 2. Heavy traffic roads (Carrying 251-600 vehicles/day) 3. Medium traffic roads (Carrying 70-250 vehicles/day) 4. Light traffic roads (Carrying < 70 vehicles/day) Highway Engineering:Introduction:2
- 15. Classification of roads according to tonnage 1. Very heavy traffic roads (Carrying > 1524 tonnes /day) 2. Heavy traffic roads (Carrying 1017-1524 tonnes /day) 3. Medium traffic roads (Carrying 508-1016 tonnes /day) 4. Light traffic roads (Carrying < 508 tonnes /day) . Highway Engineering:Introduction:2
