Pride Street?

Often a street has an alternate name or designation—there are several street signs around the city that have smaller, more descriptive street signs below them; e.g. 4th Street below South Street is also known as “Fabric Row”.
This morning I noticed a new sign attached to 13th Street, at Walnut: the smaller sign didn’t have another street name, but a rainbow! (It kinda looks like the image to the right.)
I was on the bus when I saw this, so I’m not sure if there are other signs like this one around the “gayborhood”. Has anyone else seen these?

Yep. They were dedicated on April 19: http://www.topix.net/news/gay/2007/04/philadelphia-mayor-marks-new-gayborhood.
That’s so awesome! An excellent answer to my questions. Thanks so much!
