Kicking it off at Southwest Highway and 99th Street in Oak Lawn, Illinois!

This intersection is skewed, and as of 2019, every far side head was a 3M signal!
https://www.google.com/maps/@41.7122729,-87.7766012,3a,75y,36.95h,89.38t/data=!3m6!1e1!3m4!1s-wQJy7XAwggvPTpj20hHaQ!2e0!7i16384!8i8192

It also show's Chicago's classic 70's configuration for mounting signals, with its longest trombone truss, one signal overhead, and every possible supplemental except for near-left!

Also of note is a similar intersection at 97th street, where some of the 3Ms were replaced by McCains, and some signals are simply louvered. My mom got a red light ticket here, too!

Here's an awkward interchange in Del City, OK that has them. From 1995 or so to 2011 (https://www.google.com/maps/@35.4496461,-97.432741,3a,46.6y,85.43h,92.68t/data=!3m7!1e1!3m5!1sXh9Ye-KfQNc3C40garHXsA!2e0!5s20110801T000000!7i13312!8i6656), they were all 3M signals. Later the city redid the street through here, and they got McCain PV (https://www.google.com/maps/@35.4497214,-97.4326436,3a,45.7y,113.68h,96.58t/data=!3m7!1e1!3m5!1svnsrwdXUE8FjWoZ5KLPM_Q!2e0!5s20170801T000000!7i13312!8i6656) signals. Now the state is redoing the interstate through here, so who knows what will go up next.

A few in my area

NY 33 at Westside Dr. (N. Chili, NY). All 3M signals.

Pixley Rd. at Hinchey Rd. (Rochester, NY). Signals past the RR tracks are 3M.

I can think of many but here are my favorites.

I miss this complex intersection in South Bend that is now gone: https://goo.gl/maps/7baSVQEhKDUzsAmP9
No fewer than 11 3M assemblies facing all sorts of directions.  All gone now, sadly.

Another South Bend classic with tons of 3Ms that are now gone:  https://goo.gl/maps/kyZUcSMHjxYr7Vmd8
Like 3M arrows? You'll like this one.  With overhead and lower heights.  Some mounted on a sign cantilever.  Something for everyone!

From Copley, Ohio in the "now gone" category, this one what was replaced with more pole clutter and signals you can see that aren't for you!  Bring back the 3Ms!  https://goo.gl/maps/VJeSANYaPbkGVgfq8

This Newark, Del. street view (https://goo.gl/maps/oYGvXrysE1kWv9Qw5) must have been taken within a few days of when I was there and saw the same thing--the 3Ms from the mid-90s still going but their replacements (not PV heads; I think that is a mistake) already up and waiting.  (I say it is a mistake to not use PVs because having lived near that intersection once, I saw many near-misses and actual accidents, the worst involving seeing a pedestrian flying through the air after being hit--fortunately he was OK as it could have been much worse! 

For a few that have managed to not disappear, these ones in West Lafayette, Indiana are nice having been around ~30 years and surviving a couple projects around them.  https://goo.gl/maps/goa1haXR1EpcTEpi7

This pair of pairs (https://goo.gl/maps/MAYdX5gQCTZoAQWc9 , https://goo.gl/maps/PA1Q16MNJ1gAuZko7) has served on the other side of the Wabash in Lafayette for over 25 years and were some of the earliest McCains in the area, serving the second signal each way at the offset intersection.

This one ground-mount McCain in Lafayette never made sense as it is not visible from 9th Street and is no longer visible when you are at the stop line.  The overheads are not PV signals.  It's like the Railroad Relocation people had paid for a PV signal that they didn't know what to do with so they just said put it somewhere!  https://goo.gl/maps/8RrhGVxAixzw8iUT6

Like 3M pedestrian signals?  Washington, DC has 'em!
https://goo.gl/maps/6iZMAQNYikjFyJ2w9
https://goo.gl/maps/8rqayaR7rt4SgwfR6
https://goo.gl/maps/zac6pDLKg59Gs4BE8
https://goo.gl/maps/RF5khRRSkRogjFsD7 (note the backwards orange hand symbol; other views better show the WALK pedestrian walking left, not right)
https://goo.gl/maps/qPxS7Ko6ZFAtEpBx6 (note the leftward-walking pedestrian symbol; change date to see it also has a backwards hand)
https://goo.gl/maps/FFD9TdbP3J1PTVXq7  (This one, a 3M with worded lenses, is best.)
I have good pics/video of the ones at Pennsylvania and 12th from 2018.

These two late 80s assemblies in Peabody, Mass at an offset intersection (https://goo.gl/maps/RW6tPFXvmzXKZKLHA , https://goo.gl/maps/t9pJgdSZyGSPDvYT7) show a weird mishmash of then-Mass DPW, later MassHighway and now MassDOT styles with the spanwire being one the earlier Mass installs of such, and then the other intersection having mast arms.  The brown paint on all the poles was particular to the late 80s reconstruction of MA 114 in Danvers and Peabody that the state did.  Many of the other brown poles and the signal heads from then have lately been replaced, so I fear for these 3Ms.

Salem, Mass has my favorites of all, hanging on for a very long time now for dear life, with 4 out of 6 visors missing between the two of them.

This one in Wells ME just got turned on a few weeks ago near where I live. All of the approaches use McCain PV signals and replaced a set of beacons (https://www.google.com/maps/@43.332024,-70.6256377,3a,29.5y,315.17h,88.92t/data=!3m7!1e1!3m5!1sM-MWUVm4ueOBaKLwPp9tMw!2e0!6shttps:%2F%2Fstreetviewpixels-pa.googleapis.com%2Fv1%2Fthumbnail%3Fpanoid%3DM-MWUVm4ueOBaKLwPp9tMw%26cb_client%3Dsearch.revgeo_and_fetch.gps%26w%3D96%26h%3D64%26yaw%3D280.77902%26pitch%3D0%26thumbfov%3D100!7i16384!8i8192).

(https://i.ibb.co/Dr4rytN/IMG-4377.jpg) (https://ibb.co/vX1XGHb)

Planset: https://www.maine.gov/tools/whatsnew/index.php?topic=DOT_projects&id=4176379&v=full-archive-2016

While we are talking about intersection beacons... here are a set of PV beacons (https://www.google.com/maps/@43.3412409,-70.5642184,3a,74.8y,257.22h,95.64t/data=!3m6!1e1!3m4!1sj_Wyfx3PsBl456YqMmMI9Q!2e0!7i16384!8i8192) on the side street not too far from the signalised PV's on Route 1.

Can't say I've seen PV beacons before. Nice!

I'm always intrigued by a decision to use PV signal heads when there doesn't really seem to be a need. Most of the approaches in this photo seems like they wouldn't need it. I get it for the 9A approach that curves in, but the other angles don't seem that sharp where there'd be confusion among the signal heads.

There's an intersection in Grand Ledge, Michigan, that has McCain PV BEACONS! As far as I know, PV beacons are quite rare.

PV beacons seems like a big expense for very little gain.
