The recent topic about multi-state state routes got me thinking-how many state routes extend over more than 2 states? 2 state state routes are common as a way of continuity between states, but many of these routes don't go very deep into their respective states. Long such routes seem to be fairly rare. Examples I know of where they extend into more than 2 states:
WY/NE/IA/IL 92
SD/NE/IA 2
SD/NE/CO 71
IA/MO/AR 5
Interestingly, NE/KS 15 comes close on both ends to extending into other states-it ends at the SD state line on its north end(continuing as SD 19) and at the OK state line on its south end(continuing as OK 18).
Are there other examples of state routes that extend over more than 2 states?
A few early New England interstate routes do this...
CT/MA/VT 8
VT/NH/ME 9
CT/MA/NH 10
VT/NH/ME 11
CT/MA/NH/VT 12
ME/NH/VT 26
CT/MA/NH 32
I nominate ID/MT/ND/MN 200 as the longest: 1,354 miles. (But I might be wrong!)
NE/KS/OK 99
Edit: Ha, more than 2
FL/GA/SC 121, which is fairly remarkable in that (a) FL 121 actually fits properly into the state's grid system, and (b) it ends in South Carolina at US 21, meaning it could theoretically be made into a US route while keeping its number.

Unfortunately, the US 121 designation is unwisely reserved for the Coalfields Expressway in WV and VA. I saw unwisely because the only way it could ever intersect US 21 is if it were reinstated from Wytheville, VA at least as far as Beckley, WV.
Heh, while looking at GA 121's route, it appears that US 23 and GA 23 actually multiplex at Folkston, near the FL border.
The ones I can think of in VA are:
NC/VA/WV-VA 16
SC/NC/VA-VA 49
very very rare in Europe (at least AFAICS), Norway/Finland have their route 93s forming one road (which almost seems to be coincidence, as they both fit the numbering systems), and the Northern Irish A1 forms a continuous route with the Republic's N1. Other than that, you only get them where countries were one country until recently - former Yugoslavia, former Czechoslovakia, that kind of thing.
Oh, Poland's A4, lines up with the German A4 but that's a Reichsautobahn and IIRC, an original number that didn't get changed.

The piece in Florida used to be SR 23 (and there are still a bunch of CR 23*s near the border). I don't know why they renumbered it unless it was because of possible confusion with US 23 (like SR 27 became SR 997/9336 and pre-1945 SR 19 became SR 500).
Before parts were promoted to I-86, there was PA/NY/NJ 17.

Prior to the extension of US 377, this also included Texas's SH 99 as well (not today's incarnation of the route)!

And that PA section was a duplicate to the "real" PA 17 which runs southwestward from US 11/15 at Liverpool.

Overshadowed by I-5: CA/OR/WA 99
a lot of route 96 is the Denver-Joplin highway, and I am mildly surprised it didn't get a US route number in 1926.
have we mentioned MA-295 yet? It is a short spur that is an extension of NY-295. For many years it was signed as "to NY-295" before getting its own number. it happens to be the only route number in Massachusetts that is used twice: there is an I-295 as well.

After US 99 was decommissioned, the three 99 routes do not connect with each other (Washington's in particular starts quite a ways north from the end of Oregon's).

Nope. Probably because it only exists in 2 states while the thread is looking for routes that are continuous in 3 or more states.

well, all they need to do is build that middle segment to connect the MA/RI and the MA/NY halves ;)

no, you are quite right on that one. it is indeed the longest. I've always thought it should be US-402, or perhaps a western US-4. It can absorb WA-20 as well.

If it were a western US-4, it'd be north of US-2 in (nearly) all of Washington, and therefore probably a thorn in the side of most road geeks. :) It would at least share the roadway or be south of 2 in the other states, I believe.

I wouldn't mind seeing US 402 there, but then again, it could also become US 102.

Sorry about that. I must've drawn a blank on MSR's that weren't mentioned yet, and I just thought wrong.
There is TX/OK/K-23 from U.S. 83 in Lipscomb County, TX, to K-156 west of Kalvesta, KS. Part of this Route 23 in Oklahoma is shared with U.S. 270.
Theres CT/RI/MA 138. Not very long, despite entering three states, including crossing RI at its widest point.
I think we've had this discussion, but would PA/MD/DE 896 count? :sombrero:

We have had this discussion, and the supposed Md. 896 isn't signed. So I'd say no.
It's not two states, but it crosses a state line twice: NJ 440, NY 440, NJ 440 from Jersey City to (approximately) Metuchen via Staten Island.

MA/NH 28 doesn't go anywhere near RI. Starts down on Cape Cod, passes through Boston, and heads up to NH.
It is (I think) the longest state route in MA, though.
I wonder which one I was thinking of.
28 is longer than 9 and 2? dang.
You were probably thinking of 138.

Well, my roadgeekery is of the practical variety: I'm interested in the geography of roads rather than, say, paving types or lane counts. I'm inclined therefore to disregard unsigned routes. (If I were a cartographer, I wouldn't show them on my maps because showing a route number that doesn't exist on the ground is useless if not actually misleading.) Now the 200 feet of unsigned road in Maryland between Del. 896 and Pa. 896 may not be as...consequential...as the supposed I-478, but by that principle....
Prior to the decomissioning of the MI leg, there was IN/MI/OH 120.
NY/PA 5 does come close to crossing into other states on both ends (OH on the west end, MA or VT on the east end).

BZZZZT! You're shortchanging the north end by 120 miles. The north end of K-23 (and thus, the three state duplex) is at K-383 near Dresden

I'm not 100% sure, but I think it is. It crosses at MA N-S at its widest point, plus adds the long hook around the Cape's south shore.

For a convenient crack estimate of each route's length, I checked the Clinched Highway Mapping site. Sure, the figures
will be a little off, but stuff's in the right ballpark. I didn't wanna take the time to trace out Google driving directions that stayed on route...
MA9: 132.9 mi
MA2: 139.6 mi
MA28: 149.4 mi
US20: 149.4 mi (Yes, same thing, not a paste-o.)

Now that we're including historic routings in this thread, Didn't WY-789 continue from Canada to Mexico at one point in time?
Yes, WY-789 once ran through Montana, Colorado, New Mexico, and Arizona.

And before Quebec's renumbering highways, PQ-2 (now PQ-338/A-20/PQ-138/PQ-132/PQ-185) linked both former ONT-2 and NB-2 while PQ-17 (current PQ-342) linked with ONT-17. NB-2 and NS-2 was also once linked together before TCH-104 opened.
789 used to be one but it's only left in Wyoming
