National Highways connect major metropolitan cities and state capitals and are constructed and maintained by the Central Government (NHAI), whereas State Highways connect state capitals with district headquarters and are maintained by state governments.
Why is water transport considered the cheapest mode?
Water transport requires no track construction or maintenance costs and has high fuel efficiency for carrying bulky and heavy goods over long distances.
