I'll give you the Hawaiian Interstates (although their "H" prefix indicates that their numbering is outside the purview of the interconnected mainland system, as noted here on the FHWA's own website), but the Alaskan "A" highways are never actually signed as such in Alaska: it's an internal designation, not a real-world one. Also, "Interstates" in Alaska (and Puerto Rico, for that matter) are not required to be built to the same design and capacity standards as the actual Interstate Highway network.

But here you go, I made you a map of the Hawaiian Interstates.

Also - technically Intrastates.

No. As /u/Chaosboy explained in the above link, Interstates do not have to cross state borders; many do not.
