Tagging suggestions for Louisiana

See Louisiana/Highway Classification for information regarding highway tagging.

Route relations

Some highways are moving from the old way-based tagging scheme to the new route relations. Each relation should have network=* and ref=* keys, as well as a symbol=* key with the URL to the SVG image found on the highway's Wikipedia article. If the entire route has the same name, the name=* key may also be specified on the relation.

Interstate highways

Mark all member relations as network=US:I; ensure tables in Interstate Highways Relations are up to date.

U.S. Routes

Mark all member relations as network=US:US. Please keep this list synchronized with United States Numbered Highway Relations‎. If "status" is blank for a column, that probably means the relation is not yet used in Louisiana.

State and Parish Routes

Tagging conventions are kept at United States roads tagging/Routes#Louisiana. Some parish roads were tagged with network=US:LA:PR:<parish>. This was never fully adopted, and the more standard tagging scheme network=US:LA:<parish> is now recommended for parishes with numbered road networks.

The following incomplete table contains a list of Louisiana highways. See DOTD website for maps of state highways by Parish. Some highways may be included in the DOTD's road transfer program (RTP) and are noted as such. These should be checked regularly as they could be transferred to local ownership.
