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 covered in the road naming page.
All 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.

Note: Some states are in the process of considering a change and may be designated with cnsd.
If you are an editor for a particular state that feels your state should consider a different format than you see above, please come to the US forums and select the sub-forum region for your state. In that sub-forum start a discussion around making a change to the naming convention for your state and tell the reasons why you think it should be done. Once consensus is reached the change can be made here.
General discussions on this page can be found in this thread.
