Are there any others like this in the US ?

Cool setup!
Spokane, WA will use post-mounted doghouses instead of towers on the left side of an intersection, but I'm not aware of any intersection in the city that uses only posts: https://goo.gl/a6r1FM
Illinois doesn't have doghouses, but this might be Illinois's equivalent using 5-section heads https://goo.gl/maps/7VPHUQHA1YG2

Damn, that center on the northwest corner of 75th and Lemont is going to be dead.
Philly has a few intersections with some pedestal mounted 5-section heads. As for the rest of the state, Doghouses are only at mast-arm supported only intersections. Mainly because the state didn't use doghouses until the seventies, when mast-arms became the standard.

That imagery really shows the contrast between the City of Chicago and the suburbs across the street.
Philly is the only part of the state left that still uses fully pedestal mounted signal installs. These aren't doghouses, but they're 5-section heads, which is close enough: https://www.google.com/maps/@40.0648687,-74.9822398,3a,75y,161.1h,67.64t/data=!3m6!1e1!3m4!1sEGABvtv21UfowTDLTTN9bg!2e0!7i13312!8i6656?hl=en
Here's another 5-section head at a pedestal mounted only intersection:
https://www.google.com/maps/@40.0819355,-75.1716447,3a,75y,177.22h,102.28t/data=!3m6!1e1!3m4!1saTEOxgwdlylpS2WDuaaqig!2e0!7i13312!8i6656
This however, actually is an extremely rare type of setup, a doghouse at a pedestal-mounted only intersection:
https://www.google.com/maps/@39.9648171,-75.1767397,3a,29y,299.94h,98.08t/data=!3m6!1e1!3m4!1swSOEFsUdpEHmizNEQQDGkA!2e0!7i13312!8i6656?hl=en
Philly also uses 4-section heads at pedestal mounted intersections too:
https://www.google.com/maps/place/State+Rte+1001+%26+Rhawn+St+%26+SR+1001,+Philadelphia,+PA+19111/@40.072853,-75.0758325,3a,75y,346.4h,93.4t/data=!3m6!1e1!3m4!1smGPdVzJ-FweaxmprvnElSg!2e0!7i13312!8i6656!4m5!3m4!1s0x89c6b14c2c8542d3:0x44006a85d890388!8m2!3d40.0728738!4d-75.0758571
Urban areas like this have intersections that aren't wide enough, that's why pedestals are very common in this city.
As intersections with ONLY side-mounted signals are very rare in Virginia, the only example I can think of, with doghouses, is on SR-645 at the I-66 HOV ramp in Fairfax County, https://goo.gl/maps/ZysdZajRem42 . As a bonus there are two doghouse signals here, including a (rare for Virginia) supplemental near-side doghouse.
There are plenty of other places where there are side-mounted doghouse signals in Virginia, but they are always at intersections with overhead signals too. For example, SR-638/Rolling Rd at SR-652/Burke Rd in Springfield: https://goo.gl/maps/8UMjm6DVbJS2

A bit off topic, but why make that ramp reversible, when clearly it can accommodate 2 lanes? Seems like a dumb idea....

That lane width is 20 feet wide. You need at least 24 feet for 2 lanes.
I've heard of 10-ft lanes before. Narrow, but not unheard of.
Wouldn't the lanes be narrower than 10 feet if you only have 20 feet of room (e.g., just striping takes up space)?
12' is standard, but 10' is acceptable. And the lane widths include the striping.

Nitpick: There's one in Naperville, (https://goo.gl/maps/kikBk9dSm2m) and one is planned for the Longmeadow Parkway/IL 62 intersection (project was let last November).
Iowa City, Iowa has one for the Iowa Avenue at Madison Street intersection. (https://goo.gl/maps/mfvoCNEVV3t)
Not a "side signal only" intersection, but Nevada had one example of doghouses mounted on posts. Craig Rd & Rainbow Blvd in Las Vegas had the doghouse signals on Craig mounted in the medians (2009 Street View (https://www.google.com/maps/@36.2403391,-115.2425223,3a,75y,59.76h,92.84t/data=!3m7!1e1!3m5!1s5ZabKmHgim48K_UNsZVg-Q!2e0!5s20090501T000000!7i13312!8i6656)). Dual left turns were installed circa 2010, so the PPLT doghouses were replaced with protected lefts–but it remains one of the few intersections in the state with post-mounted left turn signals located in the median (2017 Street View (https://www.google.com/maps/@36.2403023,-115.2425119,3a,75y,59.76h,92.84t/data=!3m6!1e1!3m4!1s9e3qfmYazYz1qjtAvj2KoQ!2e0!7i13312!8i6656)).

I don't see the lane width the issue as much as the timing and usage of HOV lanes on I-66 as this is an HOV-only exit. I presume some changes will be made with the upcoming HOT lanes project as HOT will run both directions 24/7.

Interesting that none of the approaches had a far-left supplementary signal. My impression has been that Nevada has always used them.
A very BC-look now, with three all post-mounted left turn signals.

Doghouses are far more common out here for left turn signals, but I still see towers from time to time. Are doghouses really that rare in Illinois? Like, this is the first one ever?

Doghouses seem to be rare in that part of the US as a whole. However, I met-up with a guy from Wisconsin down here in Alabama back in 2016, and he remarked how it was weird seeing doghouses all over the place down here as he didn't see them back where he lives.
It's just IL, MN, and WI that don't have doghouses really at all. At least that's all in this area. I'm sure there are other states that don't use them, like maybe CA.

California uses towers when mounted on a mast or pole, but a doghouse when used overhead. Granted, Caltrans rarely installs 5-section permissive signals. Cities seem to be the only ones to use them (thought they use the same placement standards).

I know a few states where doghouses are normal. In Pennsylvania, especially in the southeastern part of the state, they're extremely common, Delaware, not so much, New Jersey doesn't use them often. In Alabama and Virginia, they're used every now and then.

+ Washington and Oregon, where if FYAs aren't used, there's a 99% chance the signal will be a doghouse (or in western Washington, a bi-modal four-section tower). Utah, Idaho, Colorado, and Nevada (AFAIK) all use doghouses overhead. I think Montana uses bi-modal signals like some areas of Washington.
As I mentioned before (post #2), Spokane has a particular love-love relationship with the doghouse, using the layout (https://goo.gl/a6r1FM) even on masts and poles where towers would normally be used.
I don’t think there are any signalized intersections in Utah without overhead signals. There are a few examples of side-mounted doghouse signals, like this one in Park City:
(https://farm5.staticflickr.com/4710/26285277958_dc7b611886_c.jpg) (https://flic.kr/p/G3JVny)
Side-mounted supplemental signals are relatively rare in Utah, so this kind of thing isn’t that common. But 5-section towers are extremely rare; there are probably 5 or so intersections in the entire state with them.
Overhead doghouses are relatively common, though they are gradually being replaced with FYAs (this process is much faster with UDOT signals than those operated by cities). New installations almost always use FYA, with the one exception being when a previously permissive-only intersection is converted to protected-permissive phasing without a new mast arm.

They do, at least in the Kalispell area. I can’t speak for other parts of MT.

Confirmed that Nevada uses doghouses for overhead 5-section displays. (There may be isolated cases of 5-section horizontals in use for space-constrained installations, but if one exists I don't know where it would be.)
Overhead doghouses will become more rare in Nevada. FYAs are now the norm. With the typical "overhead signal head per lane" design philosophy used in Nevada, it is unlikely to see a new doghouse signal due to the MUTCD limitations on its use. Also, there had been an active effort to replace doghouses with FYAs shortly after they were adopted in the 2009 MUTCD–I think NDOT had some safety enhancement money that they doled out to municipalities to do some replacements.

From spending time with Streetview, it looks like South Dakota may not use doghouses either. Iowa seems to have been mostly 5-section towers in the pre-FYA days, with only a few cities such as Iowa City and Council Bluffs using doghouses (although Council Bluffs uses both doghouses and towers). Arkasnas and Kansas appear to be similar to Iowa, with Kansas appearing to have a more even split between doghouses and towers.

Not in Des Moines. Most intersections with protected/permissive phasing use doghouses. FYAs have started appearing but are still relatively few in number.

At least on Streetview Des Moines appears to use a mix of doghoueses and towers like Council Bluffs, with possibly a number of bimodal 4-sections in the mix.

From spending time with Streetview, it looks like South Dakota may not use doghouses either. Iowa seems to have been mostly 5-section towers in the pre-FYA days, with only a few cities such as Iowa City and Council Bluffs using doghouses (although Council Bluffs uses both doghouses and towers).
Not in Des Moines. Most intersections with protected/permissive phasing use doghouses. FYAs have started appearing but are still relatively few in number.
At least on Streetview Des Moines appears to use a mix of doghoueses and towers like Council Bluffs, with possibly a number of bimodal 4-sections in the mix.

Yeah, it's really a mixture of all three (doghouses, towers, and four-sections with bimodal arrow). But I still maintain that doghouses are the most common.

Yeah, it's really a mixture of all three (doghouses, towers, and four-sections with bimodal arrow). But I still maintain that doghouses are the most common.
Up until the mid-1990s, Des Moines used the 4-sections with bimodal arrows. They were the older, fiber-optic type (with the dots forming an arrow). I think those have all been phased out by this point (might be wrong on this, though). Later on, 5-section towers started popping up on new signal installations toward the end of the 90s. In the 2000s, DM transitioned from yellow signals without backplates to black-on-black backplate signals, which also led to doghouses-- that might explain why they're common outside of their current replacements, the FYAs.
Whatever they are, fiber optic or LEDs, bimodal four-section heads are still being used in a number of places.

They seem to be more common than I thought. Then again, I didn't really pay attention to traffic signal equipment until relatively recently, thanks to this forum. :-D

Yeah, those are the odd ducks. For some reason, Des Moines replaced some left turn signals with 4-section LED bi-modals in the early 2000s- mainly along SE 14th St (Fleur Dr also had a few, but some were 5-section towers). The ones on Watrous and Park were the yellow fiber-optic bi-modals before being replaced, but the Aurora was a yellow 5-section tower. I think the city was experimenting with the different types, then settled on one before FYAs came in.
If you want to go back even further, signals on Fleur used to be median-mounted 8-8-12 signals with a green arrow for left turns in the 70s:
(https://i.imgur.com/9RdpOuS.jpg)
And then were replaced with 12-12-12 signals with a bi-modal 3M arrow in the 80s:
(https://i.imgur.com/ERhRLrw.jpg)
... before being replaced with 5-section towers.
(Somewhat related to the second picture, taken during the '93 floods, it seems you live in the Des Moines Metro area. Hope you were able to stay dry during the recent flash flooding!)
^^
Cool photos! I don't think I've seen a 3M bimodal signal before, at least not in this area. Are they common in some parts of the country? I may have seen one in BC, since they only use bimodal signals, but I can't think of an example at this moment.

I've seen that second picture before (in the context of the floods, anyway), but not that first one! What an odd setup.
And I live on higher ground, so I was fortunate to stay dry, relatively speaking. I ended up having to drive through some minor flooding to get to work that night, though (on Fleur Dr, coincidentally!)

Good stuff, I see that they're using arched mast-arms, just like what Pennsylvania was using at the time (During the 70s)

Don't know if this counts, but my area loves mounting right turn doghouses on the side of the pole, instead of mounting it on the mast-arm

Well, you'll be disappointed to learn that they've both been replaced with modern mast arms and signals. Picture 1 (https://i.imgur.com/XpTJREm.jpg) and Picture 2 (https://i.imgur.com/V3Rac1J.jpg). (Note that Valley Drive was, at some point after the flood in 1993, renamed George Flagg Parkway.)

Modern design (sort of -- I don't see mast arms installed without mast lighting much anymore).

We used to have a lot of them in the Joliet area. Most any intersection (pre-dating 1985, and not having an aluminum truss) had them for the left turn movement. I wish I could find a photo of them somewhere, but have had no luck to date.
They were a follows:
Red ball - standard round
Yellow ball - standard round
Green ball - standard round
Bimodal arrow (green/yellow) - 3M programmable
I just remembered this, but in both Homestead, FL and St. Cloud, FL there were four sections used instead of doghouses (or sideways towers as in the former Dade County, FL uses horizontal mounts where doghouses cannot be used). How it worked was instead of a fiberoptic arrow that could go green or yellow, the bottom was a fixed green color arrow only! When the permissive left cycle was complete the yellow normal use yellow would activate instead. The amber was used in two cycles for both straight through and left turn green endings, and the red ball stayed on with the green left arrow, but would go out soon as the left turn permissive was done.
When in normal green mode it would be three greens across and during the left turn phase it would be three reds with the left red having the green arrow.
They all were gone in St. Cloud when mast arms were introduced in the early naughts and in Homestead and along US 1, after 1995 when then Dade County replaced most span wires with the current streamline horizontals thanks to Andrew who the horizontals withstood even the category 5 storm hence why the conversion.

Interesting! That is exactly how signals in Japan work. They use single-use green arrows for left, right, and straight when necessary, in addition to a standard three orb display. When a protected movement expires, the yellow orb comes on, and then the red Orb. The red orb disappears briefly during the yellow orb phase. A bit old-fashioned, if you ask me. but the country still uses fax machines on a wide basis, so I'm not surprised that they would still use such an old-fashioned system.

Tulsa used something similar in the '80s and early '90s, with the yellow indication being a 3M PV head.
A similar phasing was used for the original protected-left signals used from the mid '50s to late '70s, which were 8-8-8-8 or 8-8-8-8-8 signal heads on the corners, or with one overhead. Pretty cool seeing straight, right, and left arrows all lit at once!
IIRC, The last of these was at 21st & Utica, removed during signal upgrades around 1978.

They were around Kendall County, IL, too, when I first moved there (mid 90s). I remember one at US34 and IL31 before Washington Street was extended northwest in Oswego, and there was another at Orchard Road and Caterpillar Dr. before Orchard was widened in Montgomery. There may have been a couple others in the Yorkville/Plano area but I can't remember where. Here's a GSV for a former setup in Yorkville, though you can't see them in action since it's just a still photo. https://goo.gl/maps/S628Yfa2hPR2

It's still better than what some intersections in Chicago proper had. I remember that 103rd and Western used to have the four section lights, but instead of a bimodal arrow, it was just a green arrow. The intersection was on timers only, with opposing leading green arrows, then the arrows would disappear with no yellow, just a short pause before the green ball appeared.

Thank you for sharing that. I've always wondered how those old bi-modal signals worked. Seems so obvious now.

Interesting how far the bi-modal signal is from the green orb. Almost like they tacked it on well after the fact.

That signal is tough. Very creative how it has a motor in the back, so the indications can change color
Though not strictly a side signal only intersection, there is this ground mounted 4-section & doghouse combo on Saville Row at Pine Chapel Rd in Hampton, VA
In the opposite direction (coming from that parking lot) is a 4-section & a normal 3-section

Though not strictly a side signal only intersection, there is this ground mounted 4-section & doghouse combo on Saville Row at Pine Chapel Rd in Hampton, VA

This side-mounted assembly is at the intersection of OH-795 and Lemoyne Road. Doghouse is used in the median on the eastbound OH-795 leg. This assembly exists as a side-mount because of Toledo Executive Airport's location on the NW side of the intersection. Have to make sure no low flying aircraft hit a signal assembly. How uncommon is it to see? There is a flasher heading eastbound with a signal ahead sign and below it is a "SIDE MOUNTED" plaque underneath it!

Never seen that type of sign before. But a great setup! Reminds me of Wisconsin, minus the trombone assembly.
Indiana 67 at Camby Road has not one, but 2 on the SW side of Indy.

If an airplane hits a traffic light which is 16 feet high, 700 feet from the edge of the runway, there's a bit more to worry about than replacing the traffic light.
And there's numerous examples of traffic lights close to runways, so "not to confuse the pilot" isn't an excuse either.
