On Route 1 in the Baltimore area, this sign instructs the right lane that it must turn onto the I-695W on-ramp. This is the northwest interchange in the Overlea area.
I've driven past it numerous times over the years, but only today did I notice the "ERA" below the symbol for I-695. I'm trying to figure out what it means but I can't find anything. My guess is it's some kind of initialism but my guesses as to what it stands for aren't turning up anything.
- E: Eisenhower, as in the Eisenhower Interstate System? Expressway?
- R: Road?
- A: Administration? Association? Authority?
I can't say I've ever noticed it on any other sign but now I'm going to start looking for it!
