Give three points to explain the role of roads in the economic development of the country.

The role of roads in the economic development of the country can be understood from the following points-

1. Roads offer door to door service and thereby, reduce the cost of loading and unloading. Roads also help farmers to move their perishable products quickly to the markets.
2. National highways and expressways link various important cities and reduce the time of travel and distance between mega cities.
3. Construction cost of roads is much lower than that of the railway lines and roads connect the fields of raw material to industries and markets.
