I don't.  While it is uncommon, there's other ways of handling this.  The
way should still be noname=yes in this case.

And this is how you would handle addresses along such a highway.  This also
comes up (uncommon but still happens) where the USPS has decided to
consider addresses with a different name than the street that frontages
it.  In an extreme example, there's a road in my region that has the name
"Officer Larry W. Cantrell and Mister Charles L. Cantrell Memorial
Highway".  The addresses along it are all "New Sapulpa Road", the road's
old name, presumably due to brevity.
