.....D.C. easily has the worst roads
for visitors in any city in any country I've ever visited. It is very
hard to find things...

1) Many roads have formal names as well as common names. The map lists
the formal name but the signs often only use the common name (i.e. U.S.
123 is formal but Foobar St. is common).

This is standard procedure everywhere. Roads have different names in
different municipalities. Route number signs are posted along the right
side at intervals. This is a federal standard that applies everywhere.

I've only very rarely seen it, at least at the level of freeways,
which is what I think the OP was talking about. Chicago has a bunch,
and it really causes confusion. I haven't seen it other places much,
though.
