Street Signs in Tucson
The street signs in Tucson are inconsistent in format. There are variations in color, typefaces, letter size, etc.
Street signs are regulated by the Manual on Uniform Traffic Devices. This manual sets the national standards for how street signs should look. These standards change over time, so that that is why Tucson has a hodgepodge of street signs.
Any time a street signs need replacement the new signs are based on the current sign standards, so the signs can be different from other signs that are near by.
