Title: Only in these two states...
Post by: hotdogPi on January 14, 2021, 08:05:34 AM
Florida and Indiana: A strict grid numbering system
Georgia and Ontario (yes, I know that's not a state): 400-series freeways
Michigan and Kansas: State route abbreviations are M- and K- instead of MI and KS
Illinois and New York: Have an intrastate I-88
Minnesota and Texas: Have suffixed Interstate routes
Missouri and Wisconsin: Have lettered routes
California and Iowa: Have letter-number county routes
Alaska and South Dakota: Capital has no freeway
Illinois and Ohio: Have an Interstate "bump" (as far as I'm aware)
Arkansas and Indiana: Allow duplicating state route numbers with no restrictions
Alaska and Hawaii: Have no US routes
Texas and Kentucky: Have enough routes that their statewide route system has to go to 4 digits
New Jersey and Indiana: 1xx must be related to xx (and the same for all 3-digit routes)
Massachusetts and Maine: Use a thin-bordered blank square as a shield
Connecticut and West Virginia: Use a thick-bordered blank square as a shield
Idaho and Louisiana: State route shield colors can be either normal or inverted with no difference
California and Vermont: Green state route shields (if we're considering states only)
Wyoming and Illinois: Have a pointless I-180
New York and New Hampshire: Regularly have alternate routes that go through the alphabet, such as NY 17K and NH 11D

(This thread is also open to traffic signals, traffic laws, DOTs, etc., as well as historical road-related comparisons.)

Illinois has 2 of those Interstate Bumps...

Are 76/80, 74/80, and 64/70 really the only 3 that exist?

I-785/I-840 in NC (although I-840 is currently unsigned along the concurrency until its entire length is complete).

Weren't there also 4xx designations for various interstates in Virginia at one point? I know I-495 was internally designated VA 413 through at least the early 2000s.

Yes.  These internal designations went away in the late 1950s/early 60s and project numbers after that used the interstate numbers once coincident state route designations were changed.  The appearance of 413 on more recent documents is a legacy error - a fully posted VA 413 has been around since since 1981.

They don't use 200-300, but there are far more than 100 4-digit routes.  Including business, unconnected, and hyphenated routes, there are 1234 state highways in Louisiana.  If you eliminate those multiples (quick count), there are 1124.  So four digits would indeed be required.

Multiple state routes with the same number.

So on that note, I think you can add Louisiana to this list too, eliminating that one.

Kind of wondering, which other states have freeway bumps (doesn't have to be interstate). Off the top of my head, although not a state, there's one between ON 403 and ON 407

Also is there a state that uses APL signage as extensively as BC? That would be another pair.

IN 2 and US 20 aren't freeways, but they do bump at an interchange.

Multiple state routes with the same number.
In Indiana it is more that IDOT has dropped roads in cities off their rolls, making roads non-congruent on each side of the city, or have neglected to either co-sign a connecting road or have dropped a highway (such as the upcoming IN-37 exit of the I-69 corridor south of Indy) leaving remaining segments on each side.

The mile markers on one segment pick up where the other left off, so I guess that means they are segments of the same route.

Also the inverted shields for Louisiana and Idaho is not totally correct. Idaho does have shields that flip from black with white to white with black.

Louisiana's aren't inverted. It's 2 different shield designs and color choices. Originals were green state with white text. The newer ones are white state with black text. It isn't an inversion of the old one (white state with green text)

Think I prefer Indiana's over Ohio, since the latter tries to fit everything in a square, while Indiana has the full road name, and exit number. For example, on the I-275 and Loveland-Madeira Rd exit, it's abbreviated as "LVLDMDA".

Wow I had legit forgotten about those other examples!

I remember threads over the years complaining about California using that style but it seems like in comparison it rarely generated mentions for other states implementing that practice too.

Washington and Oregon: centered exit tabs.

I'm not aware of other states that center their exit tabs. WA uses full-width internal exit tabs*, whereas Oregon uses actual tabs mounted above the sign, but both centrally-mount the legend and, in the case of Oregon, the actual tab itself.

* exception being SW WA, which does things weirdly and likes to use actual tabs mounted on the right edge of a sign as is normal elsewhere.

Georgia also has centered full length attached exit tabs (https://www.google.com/maps/@33.9152064,-84.3480897,3a,27.2y,257.92h,102.08t/data=!3m6!1e1!3m4!1ssimomYpUgmElcMoAkn9wEQ!2e0!7i16384!8i8192). Them and WA are the only states I know of that does this, so those 2 can be a pair for this thread.
In the past, Missouri also installed centered exit tabs, similar to Oregon's, but it's all on the sides now. There's still a couple examples left in Missouri though; here's one at I-270 and MO 340 (https://www.google.com/maps/@38.6766329,-90.4495364,3a,61.2y,207.15h,95.82t/data=!3m6!1e1!3m4!1s4xH5jjXitpPOGZnwOuVI0g!2e0!7i16384!8i8192)

No, Kentucky does this as well.

Not sure about the exact specs, but Missouri's secondary (lettered) route markers looks similar to WV's primary route markers; both are squares with a thick black border.

Washington and Oregon: centered exit tabs.

I'm not aware of other states that center their exit tabs. WA uses full-width internal exit tabs*, whereas Oregon uses actual tabs mounted above the sign, but both centrally-mount the legend and, in the case of Oregon, the actual tab itself.

* exception being SW WA, which does things weirdly and likes to use actual tabs mounted on the right edge of a sign as is normal elsewhere.

The 1971 Los Angeles exit numbering experiment had centered tabs as well:

Also in looking up Illinois's internal tabbed signs, some of them are centered:

How long before you realized that a state doesn't have to have any pattern at all, and people still don't get lost or wonder what part of the state they're in?

I tell you, I wish all route numbers were just randomly assigned.  I hate clusters of similarly-numbered routes.

I don't know why but I realized that pretty quick about Indiana. I was traveling down I-69 one day and noticed that the state highways were going in order and after looking at a map of Indiana I thought this looks exactly like the US highway system on a state highway system.

Which two states' panhandles actually deserve to be called panhandles?
Title: Re: Only in these two states...
Post by: ozarkman417 on January 14, 2021, 05:31:58 PM
Oklahoma, because you could argue that the state itself looks like a pan, though a disfigured one.

The other one was a bit more difficult to decide on. I eliminated NE and TX because I think they are too thick, while AK's is more so a series of islands. There remain a few, like Idaho and West Virginia, but, in my opinion, the one that looks the panhandleist of the remaining ones is Florida's.

Not true–this is a distinct feature of the Oklahoma route numbering system as well (reaching all the way up to SH-74F on the most-suffixed route, with one-offs for mnemonic reasons for 77H, 77S, and 412P).

Vermont has a handful as well.

If we want to count internal suffixes, throw CO and MD onto the list, because they get quite high.

New York and South Carolina: Exit number tab on freeway signs is right-aligned not to the right edge of the sign, but at the point where the border's corner transitions from straight to curve. Although new NY signs don't do this anymore.

NY example: https://goo.gl/maps/pM8qrmS5SdQ1jMzu5

SC example: https://goo.gl/maps/QgpG5B48YsQzn6Zf8

This looks better on the NY signs because the corner is actually rounded, compared to the SC signs.

Washington and Oregon: centered exit tabs.

Centered exit tabs were the norm everywhere until someone got the idea to align it based on direction and got that guidance added to the MUTCD. Technically the right-aligned exit tab for a right exit is still only Guidance in the MUTCD, although in the proposed new MUTCD it is proposed to be upgraded to Standard.

Texas and New Mexico: only states that use horizontal traffic signals consistently throughout the entire state (barring a few exceptions)

Wisconsin is iffy for this, 15 years ago I'd say Wisconsin was a member of the exclusive horizontal signals club, but it's moving to vertical now.

Though I'd stick Nebraska with TX and NM.

Washington and Oregon: centered exit tabs.

I'm not aware of other states that center their exit tabs. WA uses full-width internal exit tabs*, whereas Oregon uses actual tabs mounted above the sign, but both centrally-mount the legend and, in the case of Oregon, the actual tab itself.

* exception being SW WA, which does things weirdly and likes to use actual tabs mounted on the right edge of a sign as is normal elsewhere.

Georgia also has centered full length attached exit tabs (https://www.google.com/maps/@33.9152064,-84.3480897,3a,27.2y,257.92h,102.08t/data=!3m6!1e1!3m4!1ssimomYpUgmElcMoAkn9wEQ!2e0!7i16384!8i8192). Them and WA are the only states I know of that does this, so those 2 can be a pair for this thread.
In the past, Missouri also installed centered exit tabs, similar to Oregon's, but it's all on the sides now. There's still a couple examples left in Missouri though; here's one at I-270 and MO 340 (https://www.google.com/maps/@38.6766329,-90.4495364,3a,61.2y,207.15h,95.82t/data=!3m6!1e1!3m4!1s4xH5jjXitpPOGZnwOuVI0g!2e0!7i16384!8i8192)

The 1971 Los Angeles exit numbering experiment had centered tabs as well:

Until recently, Minnesota.

I want to make it very plain that I recognize centered exit tabs as having been a thing in many places historically. But even in the cases highlighted above: MN, CA, GA, CT...none still use centered exit tabs or centered exit legends. Georgia seeming to be the most recent of those to shift away from centered exit tabs (which, apart from using Series D, were identical to WSDOT's design).

But I believe I'm still correct in saying WA and OR are unique in that they continue to use centered exit tabs; it wasn't something one or the other has done for a long time or has a lot of remaining examples of. It's literally as simple as "WA and OR use centered exit tabs...period".

froggie: could you be more specific when you say "until recently"? I'm seeing exit tabs in MN that are right/left justified on GSV going back to 2008.

I think they're also the only two states which officially use "State Road" instead of State Highway or State Route. Could be wrong about this, but I can't find the specific thread where we discussed how DOTs officially named their state inventory.

Mississippi also has a grid that's about as strict as Florida's, except for two (10 and 20) which were re-numbered for Interstates.

What I meant to say was that both Michigan and North Carolina sign their downtowns by spelling out Downtown in All-Capital Letters.

All those other examples spells the word Downtown in mixed case letters while these two both do them in all caps.

It's certainly true that there are more and more examples of NY signs that don't do that... I suspect the reason is an increasing number of new signs being installed as spot replacements (done by maintenance forces in-house) or design-build projects (designed by the contractor rather than NYSDOT).

(personal opinion)

OK, what state are you saying has uniquely popularized the roundabout?

I wasn't exactly saying that, although I would have guessed Massachusetts, but I also wouldn't have been entirely correct, as Wikipedia says the first modern roundabout in the U.S. was built in Nevada in 1990 (https://en.wikipedia.org/wiki/Roundabout#Development_of_modern_roundabouts).

Is roundabout some strange non-Massachusetts term for rotary? :)
There actually are differences.  Roundabouts are smaller and lower speed, for one.

Officially, the designations swap where the Turnpike crosses the free road, so no concurrency. The swap between I-87 and I-90 in New York is officially a concurrency, but not the similar-looking Ohio case.

Arizona and California:  Only states to have a section of a highway or highways where the carriageways cross over and mimic driving on the left side of the road due to the grade of a mountain pass.

Texas and Missouri:  Only states that extensively marks exit numbers as a tab above the gore sign, on a separate sign as opposed to on the gore sign itself.  I know it shows up in a lot of states, but I have only seen it widespread in those two.

Texas now signs exit numbers on the gore sign. If you still see a tab, that sign is at least 7 years old. Missouri was the first place I saw tabs in the 1980s (it certainly happened before).

Think both states moved on from the tabbed exit gore signs. Don’t know much about TX’s, but the most recent ones installed in MO afaik are on MO 364 for exits 12 WB, 14, 17, and 19 EB. MO switched to the vertical style exit gore signs, similar to what MN uses, with a couple of the official MUTCD style for 1-2 digit exit numbers.

I-85 in North Carolina does this briefly as well, although you may not notice it (it took me a few times driving that stretch before I noticed).  Although not because of a mountain pass.

And if you want to get picky, many states are re-building interchanges as DDI (diverging diamond interchange) which reverses the carriageways, albeit briefly.

I am not aware of this occuring anywhere in Tennessee, other than in GSMNP where US 441 goes in a complete circle and crosses over itself completely.  But in North Carolina this happens on I-85 b/w Lexington and Thomasville, and on I-77 at the I-85 interchange in Charlotte.

Virginia and West Virginia also do this, but only when the exit number is 3 characters or greater.  So for every three-digit exit, or two-digit exit with a letter suffix.  I'd call that pretty widespread.

Here is my own contribution:  New York and South Carolina are the only two states that don't quite push the exit tabs on BGS's all the way to the left or the right.  They account for the rounded white border of the main sign, and have them so they aren't over the curve.  And I want to say Nebraska might do this as well, but I have only seen photos, and haven't been in that state in over 20 years.

St. Helens in 1980 (largely taken out by the lahar) and for HI, plenty of choices on the Big Island, among them Routes 130 and 132 from lava flows in the past few years.

(I don't believe any Alaskan highways have been affected in their recent volcanic activity, and the likes of Oregon and Wyoming haven't seen violent volcanic activity in a long time.)

For Hawaii, 132 is a county route, as is 137 which is still partially closed. 130 definitely qualifies, with multiple closures (the most recent one has been fixed, but the ones from the 1990s mostly haven't been).

Another Hawaii highway has been trashed by lava, but the closure that comes to mind was in the 1950s, before Hawaii became a state and also before it started using (except temporarily, just on Oahu during World War II) route markers.

This used to be common practice in Missouri in the button copy era, although they no longer do so.

Older BGSs in Connecticut have centered exit tabs as well. See I-95 east of New Haven.

I had included CT in my mention of centered exit tabs upthread. I was thinking they may have been the third state still using centered exit tabs, but I found a bunch of right/left justified exit tabs at the 91/95/34 interchange that confirmed, to me, that they were no longer using them. Any idea when they stopped using them? Seems like a ton of centered exit tabs still exist around CT.

I didn't see that post but I'm glad someone else brought it up. I've designed more than a few fake signs in my life, and I've always enjoyed this practice of scooting the exit tab in a bit to align with the larger corner radius of the sign it's attached to. Florida and North Carolina would be two places I'd like to see adopt this practice, as they also use rounded corners like New York but float their exit tabs several inches above the sign, a bit like Oregon.

The slightly longer Missouri River has Jefferson City, Pierre and Bismarck. It also flows within 10 miles of Helena.

Texas and Missouri:  Only states that extensively marks exit numbers as a tab above the gore sign, on a separate sign as opposed to on the gore sign itself.  I know it shows up in a lot of states, but I have only seen it widespread in those two.

Does Alabama no longer do this?  Used to be widespread there, but I haven't been to the state in 12 years.


I can only think of a handful of these remaining within Alabama, and other than Exit 3 on I-565, I'm stumped as to exactly where they're still posted.

Update to the centered exit tab WA/OR pairing:

WA is now a party of one with its centered exit tabs. Some new signs dotted around the Portland metro, much to my surprise surfing the freeways on GSV, show left and right justified exit tabs. Examples here (https://goo.gl/maps/LPDjsvPBPVi9vuQx8) and here (https://goo.gl/maps/uSGf3N6XBZrDdiSf9) (both installed within the last five years). I also checked other exits outside the Portland metro; the practice extends to multiple ODOT districts based on this exit sign in Eugene (https://goo.gl/maps/TsLsHQjjNhXughqm6). So it would seem to be a state-wide thing at this point.

So, here's a list:

States that still use centered exit tabs/justification: WA

States that have used centered exit tabs/justification but do not anymore: OR, CA, GA, CT, MO, MN (others maybe?)

New Mexico definitely qualifies - the BGS mount is a simple circle while the individual shield has the Zia sun. Idaho now uses the same blank for all applications with their recent shield redesign.

Also, add South Carolina to the list.

Yes, it goes inside the tab. Technically centered but it usually ends up being the full width of the sign: example 1 (https://goo.gl/maps/pJh8q3yWSwydZZmA7), example 2 (https://goo.gl/maps/wry3ibbWxbhBr5eeA); for signs without exit tabs, it's just stuck on top of the sign: example 3 (https://goo.gl/maps/6yCKCHrmhTRGgbEG6); modified signs usually have the standard exit tab with a left plaque above it: example 4 (https://goo.gl/maps/zsSCbau14R8VUyaN8).

What I don't know is whether the standard design would dictate placing the left plaque over the sign rather than inside the tab, if the sign was narrow in design.

This set of BGSs has been up 10 years now with new SC shields - https://goo.gl/maps/FTXuLsWdi9rs646T9

Somewhere upthread SC was mentioned as a state that always uses 3-digit shields for state routes.  Ignoring that there are still old style markers around, here are some square versions of the new shield I am aware of:

The FHWA doesn't seem to advise WSDOT much of anything. They still continue to use black-on-white HOV/toll signage (https://goo.gl/maps/1Z6RQnMPkDmsPrXC6) well after the agency made it clear that they don't want that combination used anymore.

But yes, I suspect they'll move away from this practice eventually. SW WA already uses tabs in many locations (though it's still not universal); it would be easy enough for other WSDOT regions to adopt their standards if necessary.

This brings up a possible potential new thread topic: regional DOT practices in a state
Like for example, even though Ohio mostly uses tabbed exits since day 1, the Columbus district had IDOT style full length exit tabs (https://www.google.com/maps/@39.9785485,-82.9763382,3a,75.4y,286.77h,97.08t/data=!3m6!1e1!3m4!1sCPMcYn3ycvBqNAp2tzm4Hg!2e0!7i13312!8i6656) until about 5 years ago.

I assume by "vehicles"  you really meant "motor vehicles" ; otherwise, what other underwater tunnels are left–underwater pedestrian tunnels (like at Sea World (https://i.pinimg.com/originals/4e/06/89/4e0689a1e03b77a10dc663ab0087759e.jpg))?

But if we stick with "vehicle" , Pennsylvania has underwater tunnels used by vehicles, both the tunnel under the Schuylkill River in Philadelphia carrying SEPTA's Market-Frankford subway line as well as multiple underground trolley lines, and the more recent tunnel under the Allegheny River used by PAT light rail to connect to Pittsburgh sports and entertainment complex on the North Shore.

That's of course in addition to numerous through-mountain tunnels for cars, trains, light rail...even boats (https://visitlebanonvalley.com/wp-content/uploads/2015/07/union-canal-tunnel-park.jpg).

Quote from: wriddle082 on January 16, 2021, 03:57:21 AM
Virginia and West Virginia also do this, but only when the exit number is 3 characters or greater.  So for every three-digit exit, or two-digit exit with a letter suffix.  I'd call that pretty widespread.

Here is my own contribution:  New York and South Carolina are the only two states that don't quite push the exit tabs on BGS's all the way to the left or the right.  They account for the rounded white border of the main sign, and have them so they aren't over the curve.  And I want to say Nebraska might do this as well, but I have only seen photos, and haven't been in that state in over 20 years.

This is why the key word "extensively was used.  I am aware many states do this, there is one in New Orleans, but these were the only two states where it was the norm, not the exception.  I know Texas doesn't use this practice anymore for new assemblies, but there are still a large amount of tabbed gore signs.  Until ten years ago, there were no numbers on gore signs in Texas.

Utah uses "SR-XX". "U-XX" is a roadgeek urban legend that has not been used by "normal people" in several decades.

But the original point remains incorrect because there is a third state (not Utah). Nebraska uses "N-XX", "L-XX", "S-XX", and "R-XX" for state highways, links, spurs, and recreation roads.

Or "SR XX". I've noticed a trend in recent signage towards leaving out the dash after US and SR, but this is inconsistent and I'm not sure which is official now. Hell, even UDOT's own website is inconsistent.

You may still see a handful of straggler "U" signs such as on old street blades (https://goo.gl/maps/rzzCY32bancBU8jg8) or forest service signage (https://i.imgur.com/RESLRdY.jpg), but the "U" prefix has not been used since probably the 1960s or 1970s at the latest. (Note that the forest service sign linked above refers to a route segment that was decommissioned in 1969, so it's not like they were too interested in updating their sign content.)

You forgot Utah.  State highways are still referred to as "U-10" or "U-229" - dating back from the days when the state highway badge was literally a letter U. 

I have a childhood memory of seeing SR ### used on a mileage sign in Utah.  Is that not the practice there?

Utah uses "SR-XX". "U-XX" is a roadgeek urban legend that has not been used by "normal people" in several decades.

Or "SR XX". I've noticed a trend in recent signage towards leaving out the dash after US and SR, but this is inconsistent and I'm not sure which is official now. Hell, even UDOT's own website is inconsistent.

You may still see a handful of straggler "U" signs such as on old street blades (https://goo.gl/maps/rzzCY32bancBU8jg8) or forest service signage (https://i.imgur.com/RESLRdY.jpg), but the "U" prefix has not been used since probably the 1960s or 1970s at the latest. (Note that the forest service sign linked above refers to a route segment that was decommissioned in 1969, so it's not like they were too interested in updating their sign content.)
On a related note, I've seen DOT documents abbreviate interstate highways as "IH XX" instead of "I-XX" before

I don't know how each state exactly call its state routes, but I've seen state abbreviations (CA, IL, etc), SR for State Route, SH for State Highway, C for Colorado, K for Kansas and M for Michigan.

I've never seen 'C' anywhere here.  Official or not.

Utah uses "SR-XX". "U-XX" is a roadgeek urban legend that has not been used by "normal people" in several decades.

But the original point remains incorrect because there is a third state (not Utah). Nebraska uses "N-XX", "L-XX", "S-XX", and "R-XX" for state highways, links, spurs, and recreation roads.

Nebraska highways are officially "Nebraska Highway X". "N-" is an abbreviation of this.

K- and M- are not officially abbreviations for anything–"K-32" is the entire name of the highway.

If such an I- abbreviation were ever used in Hawaii (I doubt it ever has been), it would be "I-Hxxx" rather than "IH-xxx". Local preference would be to use the abbreviation "H-xxx" (in theory, per FHWA (https://www.fhwa.dot.gov/infrastructure/hawaii.cfm), "H-" is supposed to replace "I-" as the prefix, for Hawaii's Interstate subsystem). Or, better still, just use the route name rather than the number as is done with Hawaii's non-Interstate routes, considering that Hawaiians just aren't that into route numbers, and for a long time did without them.

Correct. C-470 specifically refers to the free southwest quadrant of the beltway, which is a regular state highway that runs from US 6 to I-25. E-470 is only the tolled beltway east of I-25.

I-840 exit to I-65 does this.

I want to say Tennessee has one too, but I may be wrong. Of course carriageways cross over and you drive on the left at every diverging diamond interchange.

But the original point remains incorrect because there is a third state (not Utah). Nebraska uses "N-XX", "L-XX", "S-XX", and "R-XX" for state highways, links, spurs, and recreation roads.

Define "normal people" please.  That's a but rude.  Yes, apparently the use of "U-XX" is now limited to old timers and rural residents.  When I lived there (1985-97), hardly anyone was using SR-XX and in fact tended to refer to a state highway as a state highway.  Things change - and clearly now the SR-XX identifier is now what is in use.  But they did go by U-XX for many years.  A quick search turned up this example: "Ferron, Utah is located on U-10 at the mouth of Ferron Canyon, ten miles southwest of Castle Dale. It was named to honor A.D. Ferron, pioneer surveyor of Castle Valley, Emery, and Carbon counties."

I-87 and I-88 in New York say hello...

Incorrect. I-88 was not built to plan. It was supposed to extend east to at least Troy, possibly into Vermont. NY had the extension to Troy on the books as late as the early 90s.

I don't think WA would count. Clark County, down in the southwest part of the state (containing Vancouver), is not substantially smaller than Spokane County nor the Spokane metro area. If you look at the Portland/Vancouver metro area as a whole, it obviously dwarfs Spokane.

If I were to name WA's big population centers, I would list Seattle, Spokane, and Vancouver.

I can take out North Dakota as well by saying it has four population centers: Fargo, Grand Forks, Bismarck, and Minot. The latter three of those are close enough in population and far enough apart to count as separate in my eyes.

Missouri is a little harder, but one could claim that Springfield/Joplin and Columbia/Jefferson City count as separate population areas, despite both regions having a much lower population than St Louis and Kansas City.

With that, I can update my original claim for Nevada and South Dakota: only two states with two massively separated population centers, and almost nothing in between.

That would fit WA, definitely: Seattle, massive gap, Spokane. But since Seattle is at the two ends of major interstates, you also have to go south from Seattle. By doing so, you hit Clark County at the very southern edge of the state, which is in itself very large and part of an even larger metro area. WA is basically a triangle of metro areas.

Define "normal people" please.  That's a but rude.  Yes, apparently the use of "U-XX" is now limited to old timers and rural residents.  When I lived there (1985-97), hardly anyone was using SR-XX and in fact tended to refer to a state highway as a state highway.  Things change - and clearly now the SR-XX identifier is now what is in use.  But they did go by U-XX for many years.  A quick search turned up this example: "Ferron, Utah is located on U-10 at the mouth of Ferron Canyon, ten miles southwest of Castle Dale. It was named to honor A.D. Ferron, pioneer surveyor of Castle Valley, Emery, and Carbon counties."

Nobody is disputing that U-xx was used historically.

By the way, that quote is from a 1990 Utah place name guide written by a John Van Cott, who was born in 1911 ... which doesn't really make him a strong candidate to switch to a SR style given he predated the entire concept of numbered state highways in Utah.

I didn't say it didn't matter or exist. But it's also part of the Portland metro, so to act like it's common national knowledge and only dummies wouldn't think of it or include it as a major WA population center is disingenuous. I was wrong. You made your point.

I wasn't trying to say you were wrong. I think WA is a good example of a state where there are at least two major population centers separated by little else. But I guess I thought it was fairly well known that the Portland metro area was made up of both OR and WA, and that the WA bit wasn't just a few small suburbs.

While they're the 2 largest cities in PA totaling about 1.8 million in population, Pittsburgh only has 1/5th of the population of Philly, and there's still a fair amount in between, including 10 million people elsewhere in the state.

I was thinking of Hyder too, but I think the point is that that "section" of Alaska is theoretically–if you don't mind some adventurous river crossings–also "accessible" overland from the rest of Alaska by some world-class intrepid hiking.

Which rectangle? Out of the five metro areas (Seattle, Clark County, Spokane, Yakima, and Tri-Cities), the only set of four that creates anything resembling a rectangle is the one excluding Yakima, which you explicitly mentioned.

I would guess that he was grouping Yakima and the Tri-Cities. Which is a stretch.

The Tri-Cities alone is at least half the size of Spokane, so it's usually not considered to be as major of a metro area compared to the other three. I only suggest including Clark County in the list because it's basically the same size as Spokane; the same cannot be said for the Tri-Cities, which is about half the size of Spokane and Clark County.

That's not totally true.

I actually saw photos from one of them not long ago. I'm thinking Jake Bear posted them on Facebook, but could be mistaken.

MO and KY: Only states to share a border and have no bridge across the Mississippi River connecting them as the mostly recognized natural border, albeit a few cut off meanders of old riverbeds.

For anyone interested, here is the 1870 Supreme Court case (https://supreme.justia.com/cases/federal/us/78/395/) that decided which state the island belongs to.  Judging by the syllabus, it seems the Mississippi River flowed on both sides of the island when Kentucky was admitted as a State, yet the boundary was defined at the time to be the middle of the river.

That's not totally true. Due to the changes in the Mississippi River over the years, there are some spots of Kentucky that are isolated from the rest of the state by the river, and you access them by land from Missouri.

Minnesota and South Dakota also share a border but have no bridge across the Mississippi River connecting them as the mostly recognized natural border.  Or maybe I'm misunderstanding your sentence.

There's a "Freeway Entrance" signage (https://www.aaroads.com/forum/index.php?topic=27077) on the Traffic Control board that notes many states using such signage. However, California & Nevada appear to be the only two that post these consistently at every* freeway on-ramp with the entire "freeway entrance sign package"–the MUTCD-standard sign, route shield, cardinal direction, and downward arrow.

Meanwhile, the arrow boards commonly used in Oklahoma don't even have the capability to display chevrons. The lights are arranged in just the pattern of a double-headed arrow.

Kansas arrow boards can display chevrons but I've never seen them do so. I think I've seen them display an animated arrow that "grows" across the face of the sign.

I've always wondered if there was any intended semantic difference between the chevrons and the arrow. The Oklahoma driver's manual shows both and, by using different wording under each of them, implies there is, but doesn't make it entirely clear what the difference is (I think one is "lane closed" and one is "move left/move right" or something like that).

Both states use a pattern where there'll be one paddle upstream of the crossing as an warning that it's coming, and then one on either side of the crossing.

I could be wrong but I don't think I've ever seen them anywhere else.

I was bored, so here you go:

Alabama and Alaska are the only two states to start with the letters A L A and to also end in A.

California (CA) and Colorado (CO) are the only two states with names that start with C and postal abbreviations with a second letter that could be either the second or last letter of the state's name.

Louisiana/Alabama (LA/AL) and Minnesota/New Mexico (MN/NM) are the only two pairs of states with postal abbreviations composed of the same letters.

Connecticut and Mississippi are the only states with names that are eleven letters long.

North Dakota and South Dakota are the only two states admitted on the same day.

Tennessee and Missouri are the only two states to border eight other states.

Colorado and Kentucky are the only two states to border seven other states.

Also, there are six states with postal abbreviations one letter apart, three increasing (Delaware (DE), Hawaii (HI), and Minnesota(MN)) and three decreasing (New Mexico (NM), Utah (UT), and West Virginia (WV)).

The biggest increasing gap between the letters of the postal abbreviations is found, of course, with Arizona (AZ), while the biggest decreasing gap is Washington (WA).

Well, some say that they "could be" either the second or last letter, but the 2 letter abbreviations generally were derived from the traditional abbreviations which are used by, e.g. the Associated Press. CA comes from Calif., CO comes from Colo., DE comes from Del. - so in all three of those states it's the 2nd letter and not the last that is used for the abbreviation.

New York (https://goo.gl/maps/dvTZjog4V53aH1449) and Wyoming (https://goo.gl/maps/2nhZDHA1wGdjetbh7) are by far the most dedicated users of box beam guiderail integrated with metal bridge rails. To my surprise, they're even more ubiquitous in Wyoming than in New York.

Also, the type of bridge guardrail in my New York example above, which I believe was common there from the 1960s, was used in South Carolina (https://goo.gl/maps/E4vV1AwV3zCs8Nna8) for several years in the early '80s, though only adjacent to sidewalks.

In the UP, they do it three-handed!  The first hand represents the lower peninsula, for context.  Then the second hand goes above and to the side, representing the upper peninsula.  Then the first hand turns into the pointer to identify the exact location in the UP.

At least, I think those are the only two, unless I'm missing any.

I don't think WA strictly defines which areas are urban and which are rural, although there are urban and rural limits for freeways. There are definitely some examples of freeways being posted below what would be expected. I-5 south of Seattle (https://goo.gl/maps/DjPQEbfSa554cUJA7) and WA-18 east of Auburn (https://goo.gl/maps/iakpqs2FA5EV33Gs9) are both well designed non-urban freeways (not necessarily rural) with well-spaced interchanges, yet both have an urban limit. Traffic normally moves on both well over the 60mph posted limit, so I think WSDOT may need to either invest in some variable limits, or raise it to 70.

Edit: before I go off-topic, are you referring to not just an egregious definition of an urban area, but also very low limits within said area? Because although I think WSDOT goes a bit too far with their urban limits, I don't think the limits are too low. Not least compared to Oregon or something.

Yes, I'm referring to the combination of low urban limits and excessively broad definitions of an urban area. The aforementioned section of I-90 in PA certainly meets both of those criteria, and from what I can tell, so does I-15 through Pocatello (https://www.google.com/maps/@42.8841775,-112.4289354,3a,75y,322.91h,90.78t/data=!3m6!1e1!3m4!1sS1S6U8qYFcET24YlIcTnuw!2e0!7i16384!8i8192) (of course, 65 mph is reasonable by Northeast standards, but if they can sign 80 mph on other sections of I-15, there's no reason why they can't there as well).

I should've worded that different.

Only states where the two largest cities (Reno and LV) not connected to each other via an interstate

Up until Oregon allowed self serve gas both NJ and OR were the only two states to have full serve gas.

Ever since I moved to Oregon, I've wondered the rationale between not being able to pump your own gas. Sometimes it's really annoying waiting on the attendant to "unhook" me. (First world problems)

My only issue with Oregon has been the number of unused pumps. I'll go to Costco near PDX, and half the pumps are closed and the line enormous as there's not enough attendants.

Interestingly, the second largest city in Alaska keeps changing. In 2000, it was Juneau. In 2010, it was Fairbanks. The 2019 estimate puts it back in Juneau, with Fairbanks losing population since 2010 in absolute numbers. Fairbanks is connected to Anchorage via unsigned Interstate, but Juneau is not.

Exactly what I was thinking.  What other kinds of "double letters" are there, other than consecutive ones? 

Æ, Å', ß

Juneau's competitiveness with Fairbanks for the #2 spot is only possible because the city and borough of Juneau is one entity.  Fairbanks only counts what's within the city limits; there is a much larger population in the remainder of the North Star Borough, whereas the Juneau "metro" is all within the city limits.  In other words, Fairbanks is a much more populous metropolitan area, Juneau is only #2 because of this "quirk" that they annexed the entire borough within which they are located.  This is much like Jacksonville (Duval Co.) or Virginia Beach (Princess Anne Co.), only there is basically wilderness outside of Juneau.  https://www.google.com/maps/place/Juneau,+AK/@58.4479638,-135.2585425,8.5z/data=!4m5!3m4!1s0x5400de6c6f6a3a8f:0x65ef25aae69f311!8m2!3d58.3019444!4d-134.4197221 (https://www.google.com/maps/place/Juneau,+AK/@58.4479638,-135.2585425,8.5z/data=!4m5!3m4!1s0x5400de6c6f6a3a8f:0x65ef25aae69f311!8m2!3d58.3019444!4d-134.4197221)

But the letter M does not derive from N.

Æ, Å', ß, and W are all 'double' letters:  AE, OE, ſs, and VV.

With Delaware, Newark isn't too much smaller than Dover and Newark is within the Wilmington metro area where Dover is not. So I guess with Fairbanks and Anchorage it would exist.

Fairbanks North Star Borough is about the size of New Jersey in area while Juneau in area is a little bigger than Delaware in area. So it's about 3 or 4 times bigger in area.

Could have sworn that I saw the IH abbreviation on a sign or message board in Wisconsin.

Wisconsin would call everything "highway X" with no prefix.

As of today there are at least three temporary orange text construction signs using IH in Wisconsin:

* WB US 12 prior to I-43 (for construction on SB I-43)

* At least two in the Milwaukee area using IH 41 - US 45 for the construction north of the Zoo Interchange.

WisDOT highway plans officially uses "IH" for interstate highway.  They aren't seen in the field besides contractor error or in this case, misdesign of the orange signs.
