Editing List of Interstate Highways (section)

==Other regions==
In addition to the 48 contiguous states, Interstate Highways are found in Hawaii, Alaska, and Puerto Rico.  The [[Federal Highway Administration]] funds four routes in [[Alaska]] and three routes in [[Puerto Rico]] under the same program as the rest of the Interstate Highway System. However, these routes are not required to meet the same standards as the mainland routes:

{{cquote|Highways on the Interstate System in Alaska and Puerto Rico shall be designed in accordance with such geometric and construction standards as are adequate for current and probable future traffic demands and the needs of the locality of the highway.<ref>{{cite web |url=https://www.fhwa.dot.gov/planning/national_highway_system/interstate_highway_system/routefinder/?redirect |title=FHWA Route Log and Finder List

The Interstate Highways on the island of [[Oahu|O{{okina}}ahu]], [[Hawaii]] are signed with the standard Interstate Highway shield, with the letter "H-" prefixed before the number. They are fully controlled-access routes built to the same standards as the mainland Interstate Highways.

[[Puerto Rico]] signs its Interstate Highways as territorial routes, as the numbers do not match their official Interstate Highway designations. Many of the territory's routes are [[freeway]]-standard [[toll road]]s.<ref>{{cite web |url=http://www.hawaiihighways.com/Puerto-Rico-page2.html |title=Puerto Rico road photos |access-date=May 24, 2007 |last=Voss |first=Oscar}}</ref>
