Notes

  1. ^ Some states internally number the Interstate Highways and U.S. Highways within their state as state highways; these are not counted in the list.
  2. ^ DC-295 is the only non-national route in the district.
  3. ^ The multiple segments of FL A1A consist Florida's longest signed state highway, but FL 5 (the almost entirely unsigned designation for the US 1) is longer at 536.724 miles (863.774 km)
  4. ^ Route 47 is New Jersey's longest signed state highway, but Route 444 (the unsigned designation for the Garden State Parkway) is longer at 172.4 miles (277.5 km)
  5. ^ OK-3's length was computed using OK-3E, the older (and longer) of its two forks.
