Notes

  1. ^ a b The state name must be added where the route number is repeated in multiple locations. If the segments cover multiple states, use only the terminal state names separated by an en dash (–). In these cases, "Interstate X" should be used as a disambiguation page.
  2. ^ TxDOT uses "IH X" internally, but for consistency, we've standardized on "I-X" to match the other states.
  3. ^ For Alaska, use A-X. For Hawaii, use H-X. For Puerto Rico, use PRI-X.
  4. ^ The official AASHTO route logs and documents refer to these highways as "U.S. Route X" while "United States Highway" appears as the heading for each route in the 1989 log, United States Numbered Highways. The term "U.S. Highway X" is used by many state DOTs, and may be used in article prose where this nomenclature is prevalent.
  5. ^ a b c d e f g Hyphenation varies by state at this time
  6. ^ Named highways are at <name of road> Highway.
  7. ^ American Samoa uses four-digit numbers, padding them with the necessary zeros.
  8. ^ Replace <division> with County, District, Municipal, or Regional as required.
  9. ^ For class B roads, the leading zeros should be used
  10. ^ For class B roads, the leading zeros should be used; different countries may choose to use spaces or hyphens as appropriate within the article
  11. ^ DEx is the abbreviation
  12. ^ yy is 2 letter abbreviation for island
