I don't know, but I'm guessin' from the chain link dead-ahead that even when the light changes, yer not goin' far!
The road does go through. Just ahead of this is a blind turn followed by a long single wide tunnel and on the other side is another sign reading the same thing. That is probably more than enough information for someone to figure out where this was.
I had to register for this one, My sister lived in Boston on a dead end street with a TWENTY minute red light (19 minutes 45 seconds) it was green for 15 seconds, three times per hour. It had an oversized "no right turn on red" sign just because it was Boston. DSmith
