I just read an article about a planned resurfacing of I-40, the road I take to work every day. In April of next year they'll refresh the asphalt between 540 and the Wade Avenue exit. The same article mentions a very sensible change that's being planned for the Raleigh 440 beltway:
"The Beltline job includes plans to remove Inner / Outer Beltline signs that have confused motorists for years. Instead, the Beltline would be divided between east / west I-40, and east / west I-440."
That makes so much sense -- the Inner / Outer Beltline thing never really worked for me.
