Explain the different types of roads in India and their specific purposes.

India has three main types of roads. Local roads are near homes and help children reach school, farmers carry crops to markets, and ambulances reach hospitals. State highways connect towns and districts within a state and are built and maintained by the state through public works departments. National highways and expressways are super-fast roads that join cities across states, built and maintained by the central government. They connect with railway stations, airports, and ports. India has the second-largest road network in the world.
