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.

Probably.  The same thing exists at 83rd and Cicero on the border of Burbank and Chicago.

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....
I build roads on Minecraft. Like, really good roads.

more room plz

That lane width is 20 feet wide. You need at least 24 feet for 2 lanes.

MCRoads

I've heard of 10-ft lanes before. Narrow, but not unheard of.

Rothman

Wouldn't the lanes be narrower than 10 feet if you only have 20 feet of room (e.g., just striping takes up space)?

Big John

12' is standard, but 10' is acceptable.  And the lane widths include the striping.

Nitpick:  There's one in Naperville, 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.

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). 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).

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.

What the hell, Naperville.
We drove right past this as part of the Aurora/Naperville road meet last month.  I can't believe we didn't stop to point it out.

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 all fun & games until someone summons Cthulhu and brings about the end of the world.

I also collect traffic lights, road signs, fans, and railroad crossing equipment.

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.
