In this section, we explore the critical role played by State Highways (SH) in India's transportation system. State Highways are maintained by state governments and connect significant towns and cities, facilitating movement across states. They are part of a larger classification system that includes National Highways (NH) and rural roads, reflecting the connectivity situation in rural versus urban areas. The historical development of roads, including initiatives like the Golden Quadrilateral project, also contributes to this discussion. Understanding the significance of SH is vital, as about 70% of freight and 85% of passenger traffic relies on road transport. The section also touches on rural connectivity issues and the growing integration of transport infrastructure in light of economic growth.
