Arizona Traffic Signals

Traffic signals in Arizona are usually found as full black signals with tunnel visors and louvered backplates. However, there are some exceptions to this. Most notably Tucson, with their yellow signals. Additionally, many cities have various different setups with different poles and different signs. This page will show off how each city displays their traffic signals, along with some explanations. Cities that aren't included in this list either do not have traffic signals or their traffic signals are ADOT maintained and therefore are classified as ADOT standard.

ADOT Standard

ADOT's older signal setup was a typical gray pole with a short curved mast. Most of these have been replaced, but there are some areas that still have these poles. The standard signal setup used by ADOT used to be just a simple gray pole with a curved mast and a simple street sign (sometimes). However, in 2021 there seems to be a new style appearing with a straight mast and a solar panel. There are also some cities whose traffic signals are maintained by ADOT, however they have special poles for them (Holbrook, Sedona, and Winslow).

Apache Junction

Apache Junction uses full black signals like most of Arizona. In Apache Junction there are 2 typical signal setups that can be found. The typical setup is on a standard gray pole with a simple street sign. The other setup is on a brown pole with an illuminated street sign. I believe the only intersection that has the brown poles and illuminated signs is at Apache Trail and Old West Highway.

Avondale

Avondale has a few different signal setups. The first one is the one found in downtown, with a standard mast and a small simple street sign (there are a few street sign designs). The second setup is an older one, but very similar to the current setup with the large masts that go around the signals. In the current standard setup, the only only major difference is that the street sign is now placed on the right rather than in the middle. There are also occassionally new installations with the standard curved mast poles it seems.

Buckeye

Buckeye has one setup variant that can be found in downtown with brown poles and a simple street sign. The other variant can be found almost everywhere else in Buckeye with white poles and a mast that surrounds the traffic signals. The last area with a different setup is in the community of Verrado. Verrado has brown poles with a standard curved mast and illuminated street signs mounted on the pole.

Bullhead City

It seems Bullhead City has taken some influence from California and Nevada regarding their street signs. Other than that, it's just a typical Arizona signal setup here.

Casa Grande

The first setup here is the old Casa Grande setup that can be found mostly around downtown. It's just standard signals on a standard pole with an older illuminated sign similar to the ones found in Glendale or California. The newer standard setup is similar, although with a newer style of illuminated sign, now mounted on the side of the pole instead of on the mast. Lastly, Casa Grande has a wired signal setup at this more rural intersection of McCartney and Peart Roads. Wired signal setups are very uncommon in Arizona and are usually only seen in construction zones.

El Mirage

El Mirage is unique because they are the only city in the state of Arizona that uses horizontal traffic signals. Originally, El Mirage signal setups were just the standard gray poles with curved masts, just with an El Mirage street sign. In 2016, El Mirage started a big improvement construction project around the downtown area, which is when the new black poles and horizontal traffic signals began appearing.

Gilbert

Gilbert has three different signal setups. The first one is an older setup that uses a boxy "modular" signal mast. A bit of research has shown that these were apparently installed in the early-mid 2000s and were very short lived before Gilbert went back to using standard poles. These boxy poles are only found in a few other cities in the state: Tempe, Goodyear, and downtown Tucson. The second setup is with green painted poles, used in downtown Gilbert. Lastly, the current setup is a standard pole and curved mast, painted brown. This specific setup has an example of Gilbert's new street sign design.

Glendale

Glendale has quite a few signal setups. In downtown, the poles are black with a straight mast and the old street signs. Outside of downtown, the older setups typically have full black signals on a standard gray pole and curved mast with the old smaller street signs. Going back to downtown, at 59th Ave & Glendale Ave, there is a unique setup with standard poles and a larger centered street sign that I've only seen at this intersection. The signals also have the yellow retroreflective outline on the backplate. Finally, the newest setup has a completely different street sign design and placement, now more similar to many other cities in the Phoenix area.

Lastly, in northeast Mesa, there's an area that has unique wooden poles with black curved masts. A similar setup can also be found in Scottsdale. Additionally, Mesa has a pretty large amount of street sign variants that can be found all over the city.

Phoenix

Phoenix has a few different signal setup variants. Poles in downtown and in the Biltmore Area are painted brown, a light pink-white-ish color on the west side of the airport and in northeast Phoenix, and green everywhere else. All color variants have had 3 different mast designs throughout the years. The oldest mast design is a simple design that was common throughout the Phoenix metro area in the 1990s, a mast supported with tie rods attached to the pole. The later mast style was the standard curved mast used throughout most of Arizona. Now, the latest mast style is a fully straight mast.

There are also old gray poles with masts supported with tie rods, as well as the current gray poles with curved masts. Additionally, in downtown there are a few intersections with green poles where the signals are mounted on wires. Lastly, there's a unique setup involving a box mast spanning across Broadway Blvd for the half SPUI interchange at Aviation Pkwy (SR 210).
