What states use the blue pentagon shield for county roads?

[kphoger]

Kansas (Douglas and Leavenworth, for sure; don't know about other counties)

FYI...

Harvey CH-801
Rawlins CH-417

[US71]

Arkansas is on a county by county basis.

Washington County


Conway County


Benton County

[hbelkins]

New York (some counties)

That's accurate.
To my knowledge, there are no counties in New York that use any other county route signage besides the blue pentagon. It's either the blue pentagon, or unsigned.

Orange County has used a county outline marker.

^ Pretty sure one of the Adirondack/North Country counties also used a white-on-green square at some point in the past 15 years.  Recall seeing it along NY 3.

That would be Franklin.  They have since switched to the blue pentagon.

Ulster also used an outline shield at one time, quite a few of which are still around.  Erie also had their own shield back when their routes were still signed.  And there's Nassau which had blue and orange pentagons back when they were signed.

There are also counties which to this day sign the number on street blades (most notably Ontario, since that's all they sign them as) but not with shields.

Maryland expressly forbids use of the county road pentagon sign in the MUTCD supplement. 

[CapeCodder]

I've seen them in Scott County in Missouri. Pemiscot County uses the county outline as its shield.

I was just thinking about the MUTCD blue pentagon shield for county roads, with regards to which states use it, and how common or widespread they are within that state. Here is a list of states that I know use the pentagon shield at least to some extent - at least, I'm pretty confident about that:

Alabama
Arkansas
California (some counties)
Colorado (some counties)
Florida
Illinois (a couple counties in the Chicago suburbs; not sure about downstate)
Iowa
Kansas (Douglas and Leavenworth, for sure; don't know about other counties)
Michigan (some counties)
Minnesota
Missouri (rare, but I have seen them on occasion)
New Jersey
New Mexico
New York (some counties)
Wyoming

I'm pretty sure I got those right. Anyway, have you seen the county road pentagons used in any other states aside from the ones I mentioned above?

I know that some states sign county roads differently (the circles for "fraction roads" in WV, for example, or the white squares for lettered "county trunk" highways in Wisconsin), while some other states instead have "secondary" state-maintained roads that serve a function roughly equivalent to that of county roads (states such as MT, NC, PA, TN, and VA come to mind in that regard).

I've seen a few in Arkansas but the county where I live, (White), they don't use the blue pentagon. I've been through Alabama via US 72 and ALT 72 and the blue pentagon is a dime a dozen.

[Bitmapped]

Some counties in Ohio use it, but it's all over the board. I'd say more Ohio counties probably use a black-on-white square than the pentagon, and some use markers of their own design.

[BluesHighway]

We can add North Dakota to the list. Minnesota also changes the color of the number from yellow to white

Tennessee but very few and rare.  I last saw some in McMinn and Polk counties.  I think I saw a couple in Meigs County as well.

For most of the state, Montana doesn't use the blue shield for county roads. Most county roads are unnumbered, at least as marked, but Dawson County in SE Montana does use the blue pentagons. Not sure if there are any other counties with them.

[rarnold]

Nez Perce County, Idaho uses blue pentagons to mark county roads.

Do all the counties listed here use blue pentagons?

No.  I know Carver County still uses the white square only.  Last time I was through there (admittedly several years ago), Lake of the Woods County was the same way.  Several counties on that list use a mix of white square and blue pentagon.

It's very much incomplete but here's a rough outline and discussion of Minnesota county practices.

We can add North Dakota to the list. Minnesota also changes the color of the number from yellow to white

I've seen some that are yellow and some that are white in Minnesota.

Some older pentagons are yellow. All the new ones I've seen are white.

[froggie]

MnDOT standard is yellow writing and a white numeral, and has been such since at least 2013.  Pentagons with yellow numerals are either older signs, error signs, or put up by counties that did not use state aid funds for the project.

Florida loves them. They seem to have more of these than current state routes (The county roads here are usually old state roads).

[mgk920]

I'm pretty certain that there are none here in Wisconsin.

In Wisconsin, they use letters instead of numbers, and mark them with white squares.

Just like we do here in Missouri...except the letter roads in MO are actually state roads.

[froggie]

I wouldn't call Wisconsin's county trunk marker a "white square".  It's a rectangle and does not follow the typical county route marker format.

[kphoger]

Wisconsin uses a white rectangle inside a black square.

Missouri uses a black-bordered white square for single letters or black-bordered white rectangles for double letters.

Nah. NJ and NY are probably the two most pentagon-crazy states in the nation.
