Pentagon paradises

[jbnv]

Has someone compiled a list of the jurisdictions that make consistent use of the pentagon shield? (I'd include in the list the counties or other jurisdictions smaller than a state/province that have numbered road systems signed consistently with shields of any shape.)

If not, we can start one here.

Washington County, Arkansas

Conway County, AR (names instead of numbers)

[TheGrassGuy]

New York (except for Erie and Wayne counties, and also a few non-standard schemes predating the pentagon)

Some counties in California (such as San Diego and Monterey)

Columbiana, Jefferson, Madison, Mahoning, Ottawa, Seneca, Stark, Summit, and Tuscawaras County in Ohio

[Brandon]

On the other hand, Wisconsin is the complete antithesis of this.

[TheGrassGuy]

Washington County, Arkansas

Conway County, AR (names instead of numbers)

Those shields remind me of the county line markers on the GSP in NJ, which are shaped like pentagon County route markers, but instead of a number, they read "now entering" and then the county name.

[Rothman]

New York (except for Erie and Wayne counties, and also a few non-standard schemes predating the pentagon)

Some counties in California (such as San Diego and Monterey)

Columbiana, Jefferson, Madison, Mahoning, Ottawa, Seneca, Stark, Summit, and Tuscawaras County in Ohio

Hm.  I thought there were Finger Lakes counties that also did not consistently use the pentagon.

OK, maybe there are a few more but IDK.

Iowa: extensively throughout the state, is there a county that doesn't use them?

Alabama: most counties, though none for Madison or Etowah, almost none in Morgan County. Highest concentrations: Cullman, Cherokee, DeKalb, Chilton, Dallas with hundreds or even thousands.

Mississippi: Alcorn, Tippah, Smith, Lafayette, Yalobusha, Prentiss, and Union. Limited usage (or none) elsewhere.

Tennessee: McMinn has hundreds, but nothing in the rest of the state.

Florida: most counties, but not used in Duval or Miami-Dade Counties. Only a few posted in Monroe or Broward. Most follow old state secondary or decommissioned road numbers. A few like Sumter and Pinellas, also have their own numbering system.

Texas: a few use them...Hays, Jim Wells, Robertson, Brooks use pentagon shapes. A few more like Jackson, Lavaca, and Cass use a square or rectangle.

Kansas: haven't driven that much of it, but Harvey County has several, and Riley County had a lot of them.

Louisiana: Terrebonne Parrish uses a bunch, but not an overwhelming amount. Noted a few in St. Mary Parrish along US 90.

Arkansas: can include Woodruff , Phillips, and Cross Counties as users of the pentagon.

Missouri: Dunklin County uses them outside cities to denote township roads (?)

Minnesota seems to be mix n match 

[Brian556]

Jackson Co, Alabama sues them for all county roads.

Somervell County, Texas has them. Some are 18x18

Illinois counties that use the pentagon shield:

Lake and McHenry go ham and mark their county highways as if they are state or US routes, complete with junction markers, reassurance markers, and guide markers at intersections.  This applies to all junctions where a county road meets a state, US, or other county highway.

Many counties in Illinois post only the reassurance markers, with no banner.  I've seen this in LaSalle, Kendall, Winnebago, St. Clair, Kankakee, Iroquois, Vermilion, Champaign, Piatt, DeWitt, Logan, Macon, Effingham, Coles, Douglas, McDonough, Rock Island, Bureau, Henry, Knox, Woodford, and Piatt Counties.  Cook, Boone, DeKalb, and Kane Counties do this but not consistently.  McLean, Livingston, and DuPage will go one extra mile and provide "Begin" and "End" markers; I think Peoria County might do this as well.  I've seen Clay County mark their county roads, but it's done with the white rectangle marker like you'll see in Minnesota sometimes.

Edit: Perhaps I should have mentioned that a lot of counties in Illinois don't mark their county highways at all.  These counties include Grundy, Will, Ford, Stark, Jo Daviess, Whiteside, and most counties I didn't mention above.  I wouldn't regard Illinois is a state with county highway markers posted statewide.

Don't think Morgan County has any left anymore, as they stopped using county routes years ago from what I understand. The last one I'm aware of was in Laceys Springs and was removed some time back, it appears. Limestone County and Marshall County also lack country route shields, but on the other hand, as Brian556 mentioned, Jackson County has tons of them. I'd also say that Lawrence County, AL, has tons as well, based on my travels to/through there.

EDIT: Pike County also has a large number of them.

In New York, Monroe, Orleans, Niagara, Genesee and Ontario counties don't sign their county routes as well.

Iowa: extensively throughout the state, is there a county that doesn't use them?

Polk County (the county most of Des Moines is in) doesn't sign its county roads, so yes: at least one.

Minnesota seems to be mix n match 

It very much is. Some counties (e.g. Ramsey, Anoka) only use pentagons. Other counties (e.g. Isanti, Stearns) use pentagons to designate county state-aid highways, and white squares for regular county roads. Yet others (e.g. Carver, Itasca) only use the squares.

Does any County, other than Clark County, NV (Vegas), have a Pentagon Shielded Freeway?

[MNHighwayMan]

Does any County, other than Clark County, NV (Vegas), have a Pentagon Shielded Freeway?

Hennepin CR-62 (now MN-62) would have been before MnDOT took it over in 1988.

Suffolk CR 92 (Nicolls Rd) has a freeway segment

Updated the list.

[tdindy88]

Michigan seems to feature plenty of county highways with pentagon shields throughout the state, more in Northern Michigan and the Upper Peninsula but I think they are around elsewhere in the state. They seem to treat them like secondary state highways and even have their own number coding system based on the region of the state where they are found. County roads beginning with letters A-C are on the western half of the Lower Peninsula, those starting with D-F are on the eastern half of the Lower Peninsula and G-H on the Upper Peninsula. Also, while the pentagon shield will feature the county name that the highway is passing through it appears that the highway may retain the same number across multiple counties.

Virginia is consistent in not using it. Theoretically, the two counties that maintain their own roads could use it (and I presume the independent cities would be treated like counties for this purpose if they chose to post route numbers), but insofar as I'm aware, that shield is not used anywhere in the Commonwealth.

Osceola Parkway (CR 522) in Kissimmee; they're now posted on the freeway (tolled) segment, though it has only 2-3 grade separations.

Don't VA and WV use circles for their county routes instead?

[csw]

Southeastern Missouri uses quite a few - I've seen them along US 60 between the Mississippi River and Poplar Bluff, and north out of Poplar Bluff along US 67. Also in Perry County.

I've also seen them infrequently in central and southern Illinois - places I've seen them besides the ones Paul already mentioned are Clay, Edgar, and St Clair counties.

I have never seen one in Indiana. I think the only counties that really number their county roads are Elkhart and DeKalb, but Elkhart only posts it on street blades, and DeKalb doesn't post it at all, to my knowledge.

[TheGrassGuy]

Thank you jbnv for the expansion. I've done a little exploration of the newly listed counties on GSV, and I've noticed a little oddity in how Dunklin County, MO signs it's county routes. You see, the reassurance markers are intended to be seen from the routes that conjoin with them, not themselves. I find this very unique and interesting. (Ex:

[TheGrassGuy]

Does Arizona sign its county routes? Mohave County has CR 91 for former US 91, but I'm not sure if there are others, or even whether it's a "fake CR" like the ones in Utah.
