Where in Tucson?

Ok, here's another shot from my most recent visit to downtown Tucson. Do you know where these stairs are?

I'll give you a hint: near the end of a bridge.

And that's the only hint I'll give out. So get out there and see if you can find the location of these stairs.

I took the photo for the attention to detail. Here, in the most pedestrian of places, the builder has added tiles for no other reason than they look nice. There is no structural reason, no safety reason, no reason at all to go to the extra expense and trouble to put tiles on the risers of these steps. Most places would be happy to have the risers just be plain anonymous concrete, but not here. A this location, most of the buildings are made to stand out (oops, another hint) which adds just a bit of something to the atmosphere.

Happy hunting.
