No signage for common freeway & interchange names
This is something discouraged (prohibited?) in the national MUTCD, and some agencies (such as Caltrans) are moving away from with new/revised signs. Ultimately, more and more people nowadays use highway numbers over highway names.
Last time I read the relevant sections, it was allowed under fairly limited conditions. In Columbus, that allowance is used to post a few "memorial" designations that nobody ever uses. Besides those memorial signs, I have not seen any signed freeway names in Columbus for as long as I've been paying attention to such things -- nearly 20 years. Yet, the traffic reports consistently refer to freeway segments and interchanges by names that aren't signed. Signing these common names (
not the memorial names) would be of some benefit to visitors, particularly if nationally-published maps begin displaying the names as well.
Perhaps a topic for another thread, but...
Seriously, freeway and interchange names need to be signed, and they should be the common / traffic-report names, not memorial names. They're not on signs, and they're not on nationally-published maps; I would have to go to Wikipedia or a roadgeek website to find out for example where the Borman, Kennedy, and Eisenhower expressways are in Chicago, and personally, I'm not likely to remember such information unless I see the highways labeled as such on a map or on signage along the applicable freeways. I imagine visitors to Columbus could have similar issues, though our freeway names are a bit more obviously named. Still, our terms "Outerbelt" and "Innerbelt" could confuse some people from the east coast, who might believe these refer to the counter-clockwise and clockwise halves of I-270, respectively; in fact, that would only be one-quarter true. </rant>
