Numbering of National Highways in India
The Government of India took a major decision in 2010 to rationalize the Numbering of National Highways in India. Numbering of National Highways should be done in a such a way that it provides some clue about the geographic location and direction of particular Highway.
Method Adopted while Numbering of National Highways in India
- All North-South highways will carry even numbers.
- All East-West highways will carry odd numbers.
- All Major highways will carry single-digit or double-digit numbers.
- North-South highways will have increasing numbering from East to West
E.g. Particular North-South highway in Central India or Western India Will have higher numbering than one in East India.
- East-West highways will have increasing numbering from North to South
E.g. Particular East-West highway in Central India or South India Will have higher numbering than one in North India.
- Three-digit numbered highways are secondary roots or branches of the main highway.
E.g. NH144, NH244, NH344 are the branches of main highway NH44.
- Suffixes A, B, C, D etc. are added to the three digit sub highways to indicate a very small stretch of sub highways.
E.g. NH966A, NH527B etc.
