When was the county pentagon marker introduced?

[route17fan]

Of course, not every state uses county pentagon markers.   

Does any state have actual signed county-maintained county routes but no pentagons? Hawaii? (But don't they just sign them as state routes?)

Does Ohio have any pentagons that aren't on street name blades? Whenever I have seen a CR signed (rare), it's a white square with black lettering.

In my Ohio travels, Ohio's Madison county uses the pentagons, as well as Mahoning and Tuscarawas. Like other states, consistently inconsistent.

Inconsistent even within the county. Coming off of the Ohio Turnpike is a square for Mahoning CR 18, while the actual route gets a pentagon (just looked at that one). One thing is consistent: I've yet to see a BGS with a pentagon, with all getting squares.

Not the Ohio Turnpike, but I've seen a BGS with a pentagon on I-77 north of I-70. It's a fairly recent (Clearview) installation.

I rarely see pentagon shields in Arizona.  In fact, the only one I ever recall seeing is Yavapai County Road 78 when I go on trips to Sedona via SR 179.

Yes indeed - Kimbolton/Plainfield - Exit 54 on I-77

Ohio:

Almost every county signs its county route numbers, but most just put that as additional info, secondary to the name, on blade signs. Some counties use pentagon consistently (but not Madison county as previously noted; they put MAD CO XX on their blades, and the only pentagons I know of are surrounding a single intersection that was realigned ca 2000).  I do recall seeing a pentagon on a BGS somewhere northeast or southeast.  Some counties use standard white square, foremost in my mind Fairfield county.  A few counties made up their own style county route marker.

To my knowledge, no county makes any distinction between useful county routes with logical termini, and other roads that just happen to be county maintained.  (However, the least important rural roads are usually township maintained, so the county designation does carry some minimal implication of importance.)

Oklahoma.

Where does Oklahoma have signed county routes?

Most county roads have either blades or green signs that are attached to the backs of stop signs.

The green signs on the back of stop signs are ODOT reference markers. Top line is county number (same as on the back of your drivers license), middle line is control section number, bottom line is mileage. It has nothing to do with the county roads.

Oklahoma doesn't have county routes in the sense that other states do. One route does exist in Ottawa County, which is a former state highway and is now signed as a CR of the same number with nonstandard signs. I don't remember the exact number but photos exist on OKHighways.

Yavapai uses them a fair bit.

There are also END signs on many of them where they switch to city or state maintenance.

Mohave uses them too:

Good to know - I had just moved back home to Ohio and found my best friend from high school in Plain City and was just driving around the area when I happened upon a sample or two of the shields and just thought they were county-wide. Thank you for the info

Tuscarawas County, OH always used the white square with black lettering for CR signs. I have not made frequent enough return visits to tell you when it was done, but those signs were replaced by blue/yellow shields at some point in the past 15-20 years. Perhaps more recently than that.

[route17fan]

Come to think of it, I think Seneca County OH uses them too.

Come to think of it, I think Seneca County OH uses them too.

Not in the eastern half of the county – that's all street name blades, with CR XX or TR XX instead of names.  I pass through semiregularly on OH 4 and OH 269, and sometimes venture a couple of miles west or east of those routes on the local roads.

Since New Jersey's county route system is much more extensive than other states, when did we stop using the black on white rectangular shields and start using the pentagon ones?
