I was wondering, in which states is I-10 designated as the Pearl Harbor Memorial Highway?
I know Arizona (except in the urban areas of Phoenix and Tucson), New Mexico, and Florida have designated it as such, while I know Texas has not (the designation in Texas instead has been applied to US 290 between I-10 and Johnson City).
CA - no (CA 99 appears to be it) yes (they have two Pearl Harbor-named highways; I-10 and CA 99)
LA - appears no
MS - no (designated the Vietnam Veterans Memorial Highway)
AL - no (can't find what theirs is)
