National Highways in India have become an essence of the road network in today’s scenario as they connect the northern, southern, eastern, and western parts of India with each other. All the credit for this goes to the National Highways Authority of India (NHAI) which takes care of this road network from its construction to the maintenance. There are about 87 national highways in India which measure around 115,435 km. They not only contribute to the development of the infrastructure of the nation by connecting commercially-rich states and cities but also elevates the Indian economy as well.
With the advent of these highways, now we don’t have to stand in long queues for railway ticket or wait for the ticket confirmation anymore to travel to other states or cities. You just need to take out your car and you can take a ride to any of the states and cities without getting jampacked in the traffic. All these factors have made the life of every Indian much easier and faster.
