Does it get any better than this? (US 15/501 near Chapel Hill and Pittsboro, NC) California-style elegance in age-forgiving black = perfection in my opinion.

I never liked span wires. They seem to make the intersection look unfinished or substandard. :/
It was back in the 90's when I moved into Montana that a couple of intersections had span wires. It wasn't until at least 2004 or '05 that the city of Missoula for example put mastarms on Broadway and Russell Streets. Another mastarm was installed at Broadway and Palmer Street in 2008 to make getting out of Palmer at lot more better, and the most recent was installed at Airway Boulevard and Broadway in mid-2011 for better left-turn traffic flow (added along with a roundabout instead of a yellow bulb on span wires). They need to put mastarms at Bancroft Street and South Avenue. Man, I hate that red four-way bulb!

I've always thought trusses were ugly and mast arms looked better. Give me a straight mast arm Nevada-style any day.
From a practical standpoint, trusses are limited in the amount of signal heads they can hold, so they aren't good for wider roadways.
I've always been partial to Springfield, Missouri's truss arm design...

No! They are something the the Orange Blossom Trail Development Board approved via some wise guy engineer thought would make "The Trail" look better to everyone including painted sidewalks and the removal of overhead utility wiring along with fancy clear globe street lamps.
Basically Orange Blossom Trail always had a bad rap, due to its roach motels, adult video stores, prostitutes, and the infamous Parliment House Resort that is a gay oriented establishment, so FDOT and the OBTDB got together and thought of these things to make this section of Orange Blossom Trail more attractive. This is part of its results.
I like the mastarms in the original post, except for the extra length of mastarm left of the flashing yellow signal. It looks to me like they were too lazy to order the correct length...
Also (not having to do with the mastarm itself), I don't like when highway authorities don't put the black plates around their signals or side-mounted signals on their mastarms (a point which has been discussed at length in other threads).
I really like how Hennepin County, MN does their new signals (for example: http://goo.gl/maps/KhPCf )

Same California-esque angle and doubling them on one post is very efficient. I'm undecided though on whether they look as good as the single mounts.
I always thought the ones Milwaukee (http://goo.gl/maps/nJmUt) used to use were nice looking, with the aggregate poles and simple arm.
I still prefer the truss arms (or "trombone arms", as we call them around here), but only when the signals were mounted horizontally. IMO, it looked cleaner, as all the mounting hardware was built into the truss--no extra brackets were required). One exception were the arched arms Madison (http://goo.gl/maps/l8LSf) used to use. Only a handful remain, as many of the arms were converted to WisDOT standard trusses (http://goo.gl/maps/nHkv8), (before they standardized to utilitarian monotubes).
I kind of like the ones found along Santa Fe Ave. in dowtown Salina, Kansas... can't seem to get a good pic, though.
Ones I can't stand: These which were a short (thankfully) phase in Wichita along freeways: http://goo.gl/maps/tOqkE
Especially nasty when they rust! Whole panels simply rot away.

What's with the road in the first couple of pictures? Was it the road being treated due to icy weather?
As for masts, I'm usually able to figure out that a scene is from New Jersey in a given TV show or movie due to them. Strange, I know. :)

Yeah, that's what the subject of the photo is supposed to be, but you can see a lot of mastarms in it. I dunno if it's in service as an actual mosque; it has something to do with the Shriners.

Agreed 100%. F.Y.I The Fish Hatch- Beltline interchange area also used to have quite a few Madison Arms but those are being replaced with monotubes due to reconstruction.

Besides the (now abandoned) Wisconsin truss arm, the standard MnDOT treatment for high capacity intersections has to be my favorite setup.
Oh, and span wire and doghouse setups can kindly crawl in a ditch and die an elaborate unnecessarily painful death.
The first three photos were taken on Friday when central NC got about 2 inches of sleet and ice. Thousands of miles of NC highways were treated with brine on 3 sunny days in advance of the storm, but as you can see it was no match for the fast-falling sleet. Temps never made it above 27 so what you sleet wasn't slush, it was ice. It took me 10 hours to get to Commerce, GA where I spent the night. Too tired to get to Atlanta where I live.

where is that? what part of Mexico would need the 'BC' clarification, but be close enough to Tijuana to use it as a control city? San Luis Rio Colorado, conveniently omitting Mexicali?
Looks like the ugly ones used in PA. The only differences are PA's poles tend to be a little thicker, and the angle is a sharp turn, not curved as shown in this pic.

I rather like those as well. It's hard for me to say what I would consider "perfect", but I think those combine elements of truss and arm quite nicely. I must say, though, I'm fond of yellow.
My personal favorite WisDOT Trombone Arm signal configuration was at high capacity 2-lane intersections:
(https://www.aaroads.com/forum/proxy.php?request=http%3A%2F%2Fimg.photobucket.com%2Falbums%2Fv704%2Fpackerfan386%2Fzpsec369ffd_zpsda8bb7e7.jpg&hash=eee7128d1e9f10c8bafef872d4bb2d8e62eda21d)
I think straight mast-arms look fine depending on the signal, and if there's a shield plating around the signals. I'm not a fan of any traffic signal without that plating, which is common in span-wire and truss/trumpet-mast designs.
My perfect mastarm would just have to be the good 'ol California curved mastarm. Very minimalist and functional.

The first is actually a Hennepin county maintained signal, not city of Bloomingotn. In Minnesota, Minneapolis and St. Paul each have their own unique styles and older equipment- I saw a pair of c1950 Eaglelux "long fins" signals at Cedar and Minnehaha Parkway, other jurisdictions tend to follow Mn/DOT specs to the point it's hard to tell who owns a given signal, and have much newer equipment.
As for the original photo, the extra length does look odd to me, and I don't like the lack of signal heads mounted to the vertical poles on either side of the intersection.

^ Although I've never understood why there are so many installations where the left turn signal is mounted at the top of the red arrow section, but the through signal is mounted between the red and yellow balls.
I like the California curved mast arm, but only when there are no signal heads mounted on the curved portion. I like when all the overhead signal heads are mounted at the same relative height & orientation--which is one reason I like the straight Nevada mast arms.
I only really like the curved mast arm if the street luminaries have a similar mast arm.
This doesn't really look good, imo.

However, with rounded-bent mast arms for the street luminaries, I prefer the straight mast arms. The straight mast arms also look better without a street luminarie, imo.

I'm also partial to the traditional California-style curved mast arm.
Here are a couple of non-traditional ones:
A large "trombone" style:

http://goo.gl/maps/GUgO1
It's a rarity to see CalTrans styled mastarms in Missoula. This one is on South Russell Street on the approach to McDonald Avenue where the northbound lane has a straight mastarm and the southbound lane has the CalTrans looking mastarm.
Nearly every example on this page has signal heads for dedicated left-turn phases. Form should follow function... nothing "perfect" about inefficient left-turn phases.
That aside, i like this style
(https://www.aaroads.com/forum/proxy.php?request=http%3A%2F%2Ffarm6.staticflickr.com%2F5251%2F5395707863_c1b3f17e25_z.jpg&hash=05aecb68ad46fbd336c071e95bbda30c0a9466e8)
Kidding, i like mast arms that are as straight as possible with illuminated street name signs hanging from the mast arm.

I always thought that the mast arms in Plainfield, NJ at the intersection of Park Avenue and Front Street was a little overdone, but it may serve a purpose as perfect in durability to mother nature.

Reno has similar traffic signals on Virginia Street in downtown. I've always thought they looked hideous...
Agreed. I pointed out in an earlier post that we have these along Kellogg downtown in Wichita and at Rock and K-96, and they suck. Especially when those panels rust out, or they have retrofit new crosswalk signals into the old spaces.

Not to mention the pigeon poop....

Clicking this link, you'll see a couple of mastarm/luminary combos on South Russell Street and 39th Street at the base of the South Hills neighborhood of Missoula.

They're like this one mastarm structure KEK, Inc. showed, only with more height, about 30 to 45 feet more. They're probably a good 150 feet in height if I'm not mistaken.

This link shows you a quite strange mastarm at 39th Street, Dore Lane and 23rd Avenue. The one hovering over the northbound side of Dore Lane is perpendicular to the luminary.

I think straight mast-arms look fine depending on the signal, and if there's a shield plating around the signals. I'm not a fan of any traffic signal without that plating, which is common in span-wire and truss/trumpet-mast designs.
Actually, the practice in Illinois and Wisconsin with their truss arms in general has the back plating.
This is a signal that was installed in Montello WI in the last 10 years or so. https://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=Montello+WI&aq=&sll=39.739318,-89.266507&sspn=10.74076,21.972656&vpsrc=0&t=h&ie=UTF8&hq=&hnear=Montello,+Marquette,+Wisconsin&ll=43.792163,-89.327431&spn=0.075836,0.171661&z=13&cbll=43.792102,-89.327793&panoid=2R5CZRJeoKjDN-PVZKKT8w&cbp=12,59.54,,0,-15.06&ei=nyshUc6aCIGAwAG75YGoBg&pw=2
This one in Bolingbrook IL. The signals used to be hanging from the end at the top. When Bolingbrook converted to the LED signals, they put the "bracket" on putting the signal/arm junction in the middle. https://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=Bolingbrook+IL&aq=&sll=43.792163,-89.327774&sspn=0.076331,0.171661&vpsrc=0&t=h&ie=UTF8&hq=&hnear=Bolingbrook,+Will,+Illinois&ll=41.699064,-88.068466&spn=0.156881,0.343323&z=12&cbll=41.698755,-88.068374&panoid=Ow1vKukUvVtGflHQmFADBg&cbp=12,173.25,,0,4.14&ei=cSwhUda5L-jxwQHViICQCA&pw=2

You're mistaken. I'd wager the signal pole in your GoogleMaps link is no more than 35 feet high. The typical straight mast arm connects to the signal pole around 18 feet or so off the ground.
