ah, but they're not signed, the interstate designation is 
administrative/political (funding).

this is similar to the issue in NY (and probably other places) where 
there are roads
maintained by the state to high standards, with "reference route" 
designations, but no
signage other that the small green reference markers. putting these 
designations in
a ref tag with a US:<whatever> network would be misleading to anyone 
trying to
navigate with a map.

probably a better example are the unpaved state highways that may be found
in some parts of New Hampshire. they do have signage, are they secondary
because they're state highways?
