What are national highways ? Explain any four uses of national highway in Indian
Answers
Answer:National Highways link extreme parts of the country. These are the primary road systems and are laid and maintained by the Central Public Works Department (CPWD). A number of major National Highways run in North-South and East-West directions.
Explanation:
National Highways constituted 2.7% of India's total road network, but carried about 40% of road traffic
The majority of existing highways are two-lane roads (one lane in each direction), though much of this is being expanded to four or more lanes. Some sections of the network are toll roads. Only a few highways are built with concrete. Bypasses have been constructed around larger towns and cities to provide uninterrupted passage for highway traffic. Some existing roads have been reclassified as National Highways.
