I hope this is the right sub-thread.
The 511 logo travel info seems to be pretty universal regardless of state.
I can't find out who designed this? is a DOT standard? I just wanted more info on it's history of design. Wiki says it started in North Dakota, but was that logo carried over or standardized later?
