270-Degree Loop Sign with a 5 in the Center

(1/4) > >>

California1994:
Can you think of any place where there is a 270-degree loop sign with the number 5 in the center? California only has curve/turn signs with advisory speed numbers on them.

Advice: Use Google Maps Street View.

Alps:
5 would be impossible. The radius would be too small and therefore total distance too short to facilitate making a loop and getting under or over the highway. 15 is about the lowest you can sign a loop for.

Possible ways "5" could still end up on a loop ramp sign:
- math error
- attempt at traffic calming via signage
- vinyl direct applied copy and the other digit peeled off
- someone commissioned a sign from Jake Bear

cl94:
You could definitely see 5 on a hairpin sign, but a loop ramp? There's no radius where that would make sense.

Henry:
Even on a substandard freeway, the lowest speed on a loop ramp would still be 15. Going any lower than that would be asking for trouble.
