maybe this super-relation [1] could help you. It uses ref=66 and  
sub-relations ref=Historic 66.

I think both can be correct, ref=Historic 66 and old_ref=66. First for the  
current sign "Historic Route 66", and second for old, dismantled sign  
"Route 66".

For routes OSM uses preferred relations.
