Title: What is the highest numbered Highway in your State?
Post by: national highway 1 on April 30, 2010, 03:55:16 AM
Hi everybody,
I'm wondering what the highest numbered highways is in each state.
Conditions:
Highest numbered State Hwy
Highest numbered US Route
Highest numbered Interstate
Highest decommissioned/unconstructed/unsigned, etc. route
(&, if this happens to be, County Hwy)
Thanks!  :sombrero:

Here in the UK the highest numbered road we have is the B9177 in Scotland. I believe some US States have 4-digit numbers so there could well be one with a higher number.

For Michigan:
Highest state trunkline: M-553
Highest US Highway: US 223
Highest Interstate: I-696
Highest decommissioned/unsigned: M-554
Highest current unsigned is M-331, unless you count the Connector 496 internal designation for the Capitol Loop or BS I-375 in Detroit.
Highest County Road: hard to say. Michigan has essentially 83 county systems with very little coordination, and since all roadways that aren't state trunklines, city streets or village streets are county roads. Many counties don't sign their roads with numbers. There is the County-Designation Highway system that functions like a secondary system. The highest number there is F-97, but the last number in the list is H-63. In my home area of Marquette County, the highest number county road is in the 600s, but I'd have to dig to specify the exact number.

Marquette County is larger the Rhode Island and almost the size of Delaware, after all. When challenged to list all of the county roads in a list article on Wikipedia (http://en.wikipedia.org/wiki/List_of_state_highways_in_Marquette_County,_Michigan), I had to prove that there's over a thousand roads maintained by the county to keep the list limited to state highways only. Most county roads in the county actually carry a two or three-letter designation instead of a number.

Highest numbered route in Virginia (and I think the U.S.) is VA-90005, the hidden number for George Washington Memorial Pkwy up in Northern Virginia.

Except that isn't really a "route number," IMHO.  The GW Parkway is a National Park Service road, and the NPS didn't assign that route number, nor is it posted.  VDOT's traffic count database (which necessarily includes non-VDOT roads significantly affecting traffic on its own roads) uses that number, but probably only because it's easier to label that road in the database by number rather than with an alphanumeric label.  So I think it more closely resembles Alaska DOT&PF's six-digit internal inventory numbers (which are never posted, and are assigned even to roads that have posted route numbers) than conventional route numbers.

Alaska's highest state route number (for the general public, posted on route markers and shown on maps) is 98, though there are U.S. Forest Service routes in Alaska with higher numbers.  Highest Interstate is A-4 (same as state route 3; unsigned, like the other three Alaska Interstates).  No U.S. routes.

Hawaii's highest state route number is 8930, for a new route which may not be posted; highest posted number is probably 7310.  There's a five-digit route number in Hawaii DOT's route inventory, 74140, but that is for one of the few county roads included in Hawaii's part of the National Highway System, and the county does not use any route numbering system of its own (though some stray county route markers remain from before the county numbering was abandoned), so I would treat that like Alaska's six-digit inventory numbers.  Highest Interstate:  H-201.  No U.S. routes.

Kentucky is infamous for its four-digit state-maintained roads. Our highest posted routes are in the 3000-series* but many of them are unsigned, so it would be a crapshoot to try to figure out the highest posted route number.

*Kentucky's frontage roads are unsigned in the 6000 series and one is currently posted and signed (KY 6011 in western Kentucky) and one was signed for a few years (KY 6239 in Letcher County). Also, Kentucky's parkways have hidden 9000-series numbers and the overpass where the Mountain Parkway's westbound lanes cross over I-64 has a marker for KY 9000.

Our highest numbered interstate is 471 and our highest numbered US route is 641.

CA has a state route 905, which is supposed to be I-905 sometime.  There is a 371, which is an old alignment of 71.  There was, back in the day, a 740, which was a spur off 74.  I think that route was gone by the 30s, as was 440, which is the other number over 198 that was in the original system.

Otherwise, nearly every number is less than 285 or so, with almost all of the numbers from 1 to 285 in use.

the highest numbered US route is 199, but at until 1964 it was 466.

the highest interstate is 980.  880 if you want a halfway legitimate one.  805 if you want one that isn't a blatant renumbering of a state route for brownie points.

North Carolina:

Highest numbered State Hwy - NC 905
Highest numbered US Route - US 701
Highest numbered Interstate - I 795 (Future I 840 is signed)
Highest decommissioned/unconstructed/unsigned, etc. route
(&, if this happens to be, County Hwy) - North Carolina numbers all of its secondary roads with a 4 digit number that is unique to a county. These numbers are posted on road sign blades or on small white signs. There are thousands of them with numbering into the 2000's. What the highest number issued or posted is a major research issue, since NCDOT groups them by county.

Nebraska:

Nebraska generally has low-numbered state highways. Most are 1 and 2 digit numbers, and most 3 digit numbered highways are relatively short and/or of lesser importance. The highest regular number is 137-the only two that exceed that are NE 250, which was numbered that way because it was put into state law, and NE 370 which was numbered to match the Iowa highway that continued across the Missouri River.

Of course, you could say that US-491 is both highest state and US, as US and Interstates are seen as state routes, legislatively.

Unposted, you have some "special interest" routes used to prevent nuclear dumping near the Skull Valley Reservation, UT-900 and UT-901, which are not signed or even paved (and probably won't be anytime soon).

When did that happen and how down into Mississippi does US 425 go? Perhaps could you be confusing that with US 278? It's co-signed with 61 from Clarksdale to Leland and then from Leland westward into Arkansas on US 82.

I guess I need to find an updated Mississippi state map or hit the road more often.

as of early January 2010, 425 multiplexes with 84 starting in Louisiana, crosses the river at Natchez, and the last 425 sign is a gantry that says 425/84 (reassurance) and then TO 98, TO 61.  There is no END 425, but at the 61 junction, there are no 425 shields.

looks like USEnds has a photo from about the same time I was there of the last 425 southbound shield.

In a nutshell, what used to be US 65 in Mississippi got replaced by US 425.

Yes it was, then later truncated to Natchez, though internal MDOT docs suggested a hidden duplex down to the LA/MS line south of Woodville all the way to the recent truncation and US 425 extension.

I think the highest numbered state highway in Florida is SR-9336 down in Florida City.

It is. And more, to continue:

Unsigned State Route: 913
Interstate: 595 [so far...]
US Route: 441
Suffixed State Route (alphabetically & signed): 30-E
Suffixed State Route (unsigned): 618A
Highest County Route (signed): Volusia CR 4162
Highest County Route (unsigned): Brevard CR 5054 [Although, there are/were secret routes in Miami-Dade and the highest was 9339, and there was one CR 7865 in Daytona Beach Shores along with a CR 8388 on Marco Island]

New York:
Interstate: I-990
US Route: US 219 or US 220 (depending on where you put the end of US 220; on Upstate NY Roads it's main st (old NY 17) in Waverly)
State Touring Route: NY 890
State Reference Route: NY 992P
Decomissioned/unsigned: depends on what you count; I-878 fits the bill, as do NY 790 and NY 781 (both are reserved but not used)
I think Chautauqua county has an unsigned CR 8139, but I'm not sure what to make of it.

From what I've seen from NYSDOT route logs and from a few people questioning why I would have a US 220 ends page for the long-since-updated NY Ends site, US 220 doesn't technically enter New York.  Yes, US 220 is signed into New York State, but I'm guessing that the official end is at NY 17 (which at that point is in Pennsylvania).  US 220 (also US 309) used to enter New York State from Pennsylvania Ave., ending at what was NY 17 at the time, clearly within Waverly, NY.

There is also a signed Saratoga CR 1345 in Mechanicville.

Former: (unbuilt) I-710 Tucson

was 710 ever signed?  410 was, so that may have been the highest-ever signed interstate route in AZ.
No, 710 was cancelled by NIMBYs in Tucson.


Sounds like the 710 in South Pasadena, California.

The highest SR in North Carolina is in Mecklenburg County, SR 6023.  Wake County has made it to 5813.

The NCDOT website has a secondary route lookup feature that is useful for researching this question...

For South Carolina:
Highest Interstate: I-585
Highest US Route: US 701
Highest State route: SC 917 (historically SC 946)
Highest secondary route: don't know but I know a couple counties must be approaching 3000 by now

Correction:  it was approved by AASHTO in 1958.  Not sure about FHWA, but since it never got built, it's a fair chance the proposal never got as far as FHWA (or its predecessor).

Highest FM road in Texas is (AFAIK) FM 3549, while highest RM road is RM 3474.

In Kansas I think the maxima are as follows:  I-635, K-383, and US 400.  K-383 is former US 383, so the "natural" maximum for Kansas state routes is probably one of the state-maintained spurs with a K-2XX designation in the mid-200's.  US 400 is essentially a fake two-digit route, so the "natural" maximum for US routes passing through Kansas is likely US 283.

Yes, I was.  Also, because I forgot about US-223, and since Michigan's Upper Peninsula is, in some ways, unique to the rest of the state,  here are the highest numbers for the 3 different types of highways in the U.P.:

1.  M-553
2.  US-141
