Question

explain the highway system of India?​

Answer 1

Answer:

The National Highways Authority of India (NHAI) is the nodal agency responsible for building, upgrading, and maintaining most of the National Highways network. It operates under the Ministry of Road Transport and Highways. The National Highways Development Project (NHDP) is a major effort to expand and upgrade the network of highways. NHAI often uses a public–private partnership model for highway maintenance, and toll-collection.

In India, National Highways are at-grade roads, whereas Expressways are controlled-access highways where entrance and exit is controlled by the use ramps that are incorporated into the design of the expressway.
