Rationalisation of Numbering system of national highways

All national highways in India are rationalised based on the US Highway numbering system. All highways are numbered based on their orientation from North to South and from East to West directions. Highways which are running from north to south are given even numbers and those running in the east-west direction are given odd numbers.

The Primary National Highways which are in N-S and E-W directions are given double digits for better identification by commuters (from 1 to 99). The numbers of the Primary National Highways increase from N-S and E-W. The Secondary National Highways are given three digit numbers.

As per the new scheme, multiple highways are merged into one new Highway. After the renumbering single longest national highway is NH 44 which will run from Srinagar to Kaniyakumari. The shortest Highway is NH-36. The distance is 3.0 km only. Some popular highways are truncated into multiple segments like the Chennai-Bangalore Old Madras Road via Chitoor (NH4) becoming N48-N40-N73-N75.

Some important archaeological sites in India

Some important archaeological sites in India

Many sites were located near sources of water, such as rivers and lakes.

Bhimbetka (in present-day Madhya Pradesh).Some sites, known as habitation sites, are places where people lived. These include caves and rock shelters such as the one shown here. People chose these natural caves because they provided shelter from the rain, heat and wind. Natural caves and rock shelters are found in the Vindhyas and the Deccan plateau. These rock shelters are close to the Narmada valley.

Traces of ash have been found in Kurnool caves. This suggests that people were familiar with the use of fire.

A number of early Palaeolithic sites were found at Hungsi. At some sites, a large number of tools, used for all sorts of activities, were found. These were probably
habitation-cum factory sites.
