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. Please keep this list synchronized with Interstate Highways Relations.

Number Relation Status and notes
10 relation 34171 From St. James–St. John the Baptist parish line to Mississippi state line. One relation for both directions.
510 relation 120983 Complete. One relation for both directions, with role=north/south.

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.
