The Ministry of Road Transport and Highways in India owns a system of Modern Road Maker's roadways known as the National Highways. India's Best Highway Infrastructure has flyover access or some controlled-access, where entrance and departure are through the side of the flyover. Flyovers are provided at each highway intersection to avoid the traffic in the cities, towns and villages, and these highways are built at a top speed of 100 km/h. https://www.youtube.com/watch?v=DucTK7ejEg0
