India/National Highway Network

Warning: This page shows is the old numbering of national highways in India.

Data sources

• http://www.nhai.org/Doc/project-offer/Highways.pdf
• http://www.nhai.org/statewise.htm
• NHAI NHDP3 project map (upgraded NH)
• NHAI NHDP5 sections (6lane)

Tags for the relation

A relation should be present (created if necessary) for every National Highway. Each way making up any single Highway route is added to one of these relations. The relation should have at least these tags:

• type=route
• route=road
• network=IN:NH
• ref=NH#

The tags should always be NH#; e.g. NH22. It should not be any other variant of these such as N22 or NH 22.

If the way already has a different older-style NH number (pre 2013-2014) , that number should be preserved but the tag changed to 'ref:old'. No other tags should be present that start with 'ref', including 'ref:new'.

Notes: These tags are added to the relation and not the ways. Any given way may have and likely has a national reference, tagged as a ref=* on corresponding ways

• ref=NH1 default reference
• highway=trunk default reference

Names

Each way that is part of a highway should ideally have a local name, applied according to the guidance for the name tag. If there is no local name, then you may add a default name='National Highway xx' to that way. Do not overwrite any local name with the national designations. If you know the local name for a way, then you should replace any 'National Highway xx' given under the name tag with the local name. Note that names should be given in full and not abbreviated. If the abbreviation is common, then include it using the name:alt tag.

Routes

Note : where available, the new NH numbers are shown in parentheses before place names, but they may not be fully equivalent to the old numbering used in this table.
