I have posted pictures of various types of street signs found around the city of Houston in the past. Still, there was one type that used to grace the curbs at many intersections that I haven't had the chance to photograph. Then, in a thread on the Houston Architecture Info Forum, I found that a member called "isuredid", placed one he had taken. So, here it is.
I don't know the history of these blue and white mosaic signs, but they must have had standard tile layouts for every letter and digit, as they always were very consistent. I cannot imagine road crews today taking the time for such curbside artistry, but I have always enjoyed these signs as a piece of how things used to be done. They are much more interesting than the standard signs you typically see nowadays.
Next time I get down to Houston, I hope to catch some of these on my own, but in the meantime, thanks to isuredid for this one.
