This was at an intersection, not a curve

Are you referring to this one? If so, I already have it mapped.

I had no idea they had active E Classes! Funny thing is I've passed over those on the map and thought they were just speakers, but it makes sense they're Byron sirens since they're in a spot that I had a missing number for.
