This table identifies the specific naming conventions used for the various highway types for each state in the Unites States. Details of the naming convention is on the [[Road names/USA|road naming]] page. All [[Road names /USA#United States Interstate Highway System|interstate highways (freeways)]] are named the same across all states, so they are not included in the table below.
The state names are linked to the respective wiki page that provides specific editing guidelines (and other information) for that state. If the state link is red, there are no specific guidelines for that state yet. If you actively edit in that state consider creating that page and providing information to other editors in your state.
