Which county has the most US routes?

[Zeffy]

Actually, Atlantic has 9, 30, 40, 206, and 322. Five.

Oh wow. I could've sworn Hammonton was part of Camden County, and not Atlantic County, but looks like I was wrong.

[NWI_Irish96]

The best Indiana does is seven in Marion County (31, 36, 40, 50, 52, 136, 421), and then Lake County with six (6, 12, 20, 30, 41, 231)

US 50 misses Marion County by a good 50 miles to the south.

Wow, I think I was typing 52 and somehow typed 50, then noticed I didn't have 52 and added it.  So yeah, 50 is nowhere near Indy.

Like I said, many of us are not exactly sure of county borders in New Jersey unless you know where the town boundaries are and which towns are in which county.

New Jersey is more municipal oriented than county oriented.

Michigan's pathetic. Two counties that each have three: Lenawee (12, 223, 127) and Dickinson (2, 8, 141). Before the days of the Interstate Highway System, Wayne held the record with 10, 12, 112, 16, 24, and 25.

For those looking to research this who haven't seen the mob-rule Google Maps with county lines, it would potentially be useful:

http://www.mob-rule.com/g17?center=42,-92&zoom=4

Mapquest has county lines built in, which is a lot less memory intensive than New Google Maps with an extension, but they're also sort of hard to see until you zoom in really close.

Dane County, WI:  12,14,18,51,151

[doorknob60]

For Oregon (just looking at a couple of the top ones that I found)
Wasco County (4): US-26, US-30, US-97, US-197
Malheur County (4): US-20, US-26, US-30, US-95
Umatilla County (3): US-30, US-395, US-730
Clastsop County (3): US-26, US-30, US-101

There's probably a couple more with 3 US routes, but not really worth pointing out. When I started looking, I didn't think I'd be able to find any with more than 3, so I'm kinda surprised I found two counties with 4 US routes. Of course, thank the relatively irrelevant US-30 for that (other than Portland to Astoria, it just serves as I-84's business route), so it didn't come to mind at first. This list might be a bit more interesting if US-99 was still around.


For Idaho, I'm going to assume without looking at others that Canyon Country, with 4, is probably the most: US-20, US-26, US-30, US-95 (same list as Malheur, oddly enough, although they are adjacent to each other).

The original post disallowed the auxiliary routes. Otherwise Jefferson County, Ky. (Louisville) would have 31, 31E, 31W, 42, 60 and 150 for a total of six, stealing the Kentucky lead from Fayette County.

[elsmere241]

In Delaware, New Castle County has four: 13, 40, 202, 301.  Kent County barely has two: 13 and a short section of 113.  Sussex County has three: 9, 13, and 113.

[BrianP]

Maryland only has one county with 4 US routes.  Washington County has US 11, 40, 340, 522.

[sandiaman]

The winners in New Mexico are:  Lea County,(4) US 62,US 180, US 82 and US 380
                                                Union County (4) US 56, US 64, US 87  and US 412
                                                Rio Arriba (4) US 64, US 84, US 285 and US 550

I dunno, I was mostly thinking of bannered routes when I wrote that. These letter suffixed routes seem to at least have the status of a 3-digit Interstate as compared to the Interstate system..

[DandyDan]

Nebraska's grand champion counties for US routes are Furnas and Harlan Counties, each with 4.  Furnas has US6, 34,136 and 283, while Harlan has US 6, 34, 136 and 183.  Harlan County used to have US 383, so that would be a historical high of 5.

[CNGL-Leudimin]

California only has two counties with more than one:  Del Norte (101 and 199) and Inyo (6 and 395)

CA actually has three counties with more than one US route, the third one being San Bernardino (95 and 395) thanks to it extending all the way to AZ. I was about to complain in the counties without US routes that they ommited Riverside, forgetting it also extends all the way to AZ and thus having US 95. Formerly, San Bernardino had more US routes than any other county in CA, with 8 (60, 66, 70, 91, 95, 99, 395 and 466), with Los Angeles county coming in 2nd place with 7 (6, 60, 66, 70, 91, 99 and 101), of which only 101 remains.

So far I can not find any of Florida's 67 counties that have more than that.

I found one more in Florida with four US routes, but it's easy to miss.  Taylor County has 19, 27, 98 and 221.  They all meet in Perry.  19 and 27 are co-signed north of Perry, and 19 and 98 (and Alt-27) are co-signed south of Perry.

I know the county I live in has four.  US 17, US 92, US 441, and US 192 as well as neighboring Osceola County.

Nice catch with 192 in Orange County.  I forgot about that little piece west of Disney.

Looking at Google Maps, which has no county lines:

Which county has 19/29/41/78/278 in Atlanta? (23 might also enter the county, but it might not.)

That would be Fulton County.  US 23 (Moreland Ave) actually forms part of the eastern border of the county, so it should count as well.  That brings the total to 6.

(US 466 was completely useless in Nevada as it was always concurrent with other US routes from the beginning, while US 91 was effectively replaced by I-15).

Interesting. I'd thought that US 466 southeast of Las Vegas was there before US 93 was signed that far south. But I looked at Wikipedia (debatable as to whether the content is accurate), and it says US 466 was assigned in 1935 and US 93 was also assigned in 1935 yet not signed until 1939. USEnds.com shows US 466 was created in 1934. Did you have another source that shows both 93 and 466 were both signed at the same time between Las Vegas and Kingman from the beginning?

Nope. That was me talking without looking things up... I guess in my head I just thought that US 466 never really served a separate purpose, and supposedly it did have some independent utility for a couple years. Suffice it to say that for most of US 466's existence, though, it was pointless.

BTW: I wrote that part of the history section from the Wikipedia US 93 article (based on research done for the Nevada US 93 article), but didn't really look at the role of US 466 at the time I contributed that.

Thanks. I keep thinking 466 was there first, but the article shows that 93 joined 466 not long after 466 was born. The only reason I can think of as to why 466 lasted as long as it did was to provide a continuous route from mainline US 66 to Las Vegas, connecting at either end (more or less) with 66. Anyway, back to the topic at hand...

In Louisiana:
Caddo Parish has 4 (71, 79, 80, 171)

[thenetwork]

Ohio: 

Cuyahoga County (Cleveland) with US-6, 20, 42, 322 and 422. (also had US-21 up into the 1970s).

Lucas County (Toledo) with US-20, 20A, 23, 24, 223 (also had US-25 & US-68 also up into the 70s). 
You can debate the status of US-20A, as I consider it as it's own primary route -- it is not even close to being a short bypass around a single town and never is it bannered as "ALTERNATE ROUTE 20".  I consider 20A to rank with the likes of US-9W or 25-E.

Hamilton beats both of them with 22, 27, 42, 50, 52 and 127.

And is there really any difference between Alternate US XX and US XX-A? I don't think so. For instance, Kentucky signs it Alternate US 41 and Tennessee signs it US 41A, yet they're the same route. And I've seen some states (Virginia and North Carolina) use both the XX-A and Alternate XX signage.

Monroe County also has 3: US-23, US-24 & US-223; and Emmett County also carries 3: US-23 (barely), US-31 & US-131.

Jackson County, MO has six: 24, 40, 50, 56, 71, and 169

In Pennsylvania, it appears neighboring Chester and Delaware Counties tie with five each.

Chester:

US 202
US 322
US 422

Delaware:
US 1
US 13
US 30
US 202

You missed two:  31A and 41A, bringing to a grand total of 9.  If it carries a US route shield, then it's a US route, plain and simple.
