Hieroglyphics

I thought that the title "Hieroglyphics" would be appropriate for this street marking.  But I thought I would check, because I know you are all watching me and pity poor me if I make a mistake!   :-)

Anyhow I looked it up and this is a short definition: "enigmatic or incomprehensible symbols or writing" and that sounds perfect. I do happen to know that this symbol means there is a gas main running right under this symbol, and they mark the street when there is going to be someone excavating the street, so no one will break a gas main with a back hoe!  Anyhow, I love this image as something artistic, even though it is technical.   Something about the bright yellow paint on the black macadam and the gentle sunlight raking across the surface.  what I don't know is what the smaller text means.  If I ever find out, I will be sure and let you know.
