Decommissioned InterstatesThis set of Interstates includes those that were either signed at one point and legislatively decommissioned, renumbered as another Interstate, or planned and subsequently canceled. As planning documents arise either through library research, the internet, or other sources, expansion of the list below will occur with this information and photos as they are taken. The following code indicates whether the Interstate was Dismantled (D); Partially Completed (P); Renumbered as another Interstate or freeway designation, U.S., or State Route (R); Unconstructed (U); or Numbering Proposed but Not Approved by AASHTO (N).
