I noticed that there is a state route 12 that runs continuously through Connecticut, Massachusetts, New Hampshire, and Vermont, for almost 300 miles. It exists because a century ago, the New England states agreed on a system of regional numbered highways, which was soon supplanted by the new system of US routes. Some (e.g. route 1) were incorporated into the US system, but some of those regional routes survived only as state routes.
Are there any other state highways that run continuously through four or more states with the same number? I can see that there aren't any more in New England.
Honestly, I'd imagine it'd be pretty hard to find one larger than that outside of New England, or at least the east coast, given how much larger the states out west are in land area...
For the segments of US 66 that became state routes within their states, are they still fully continuous or are there gaps?
ID-MT-ND-MN 200 are continuous.

Yeah that's over 1,300 miles. I believe it was part of an effort to create a US route over this corridor in the 1960s.
WY/NE/IA/IL 92
That certainly beats IL/WI 78.
:-P

Some others of note from out west:
CO96/K-96 is 507 miles
CO71/N-71/SD71 is 430 miles

Which would still beat CT/RI 78
If it weren't for the existence of US 9 in NY, you could've had (PA 29)/NY 7/VT 9/NH 9/ME 9 as one route.

Probably because its just a minor route.

IL/WI 35 is the longest IL/WI route at 414 miles, but that's the road version of Wayne and Brent Gretzky being the highest-scoring sibling duo in the NHL.

And used to be quite a bit longer before the eastern section of K-96 was renumbered as part of US 400 if I recall.

Then I guess VT/NH/ME 26 would be the Vince, Dom, and Joe DiMaggio of routes.

It's certainly discontinuous in California and Arizona, and doesn't exist at all in New Mexico. I don't know about anything east of there, though.

That's a hell of an impressive route. According to Wikipedia, just the Montana portion of it is the longest state highway in the country. It sure has a lot of multiplexes, though, including with Interstates.
And TM has one user (oscar), who has traveled all of MSR 200.

The 1961 attempt for US 200 between Missoula and Duluth failed for 5 reasons, per AASHO:
1. some segments were substandard
2. no evidence of enough traffic to warrant it
3. duplicative of other US route corridors
4. no evidence the existing US route corridors are overwhelmed by traffic to justify another route
5. not the most direct routing for a US route
It was tried again in 1963-64, Spokane to Duluth, and was rejected for the same reasons
Probably would pass today given AASHTO's state.

I was thinking Hank and Tommie Aaron, but to each his own.
One would argue MT-200 is fairly major route within Montana, connecting Great Falls to Missoula, Billings, and eastern Montana. By itself, it would be a fair candidate for a US highway designation.
Not so much outside of Montana, for sure. AASHTO was correct in denying the application.

Thanks, MapMikey. Maybe they should go again, third time's the charm! And maybe the substandard sections have been improved and traffic has generally increased.
SC/GA/SC/GA/NC 28 may only be in three states but it crosses state lines four times.
There are other three-state state routes in this region, such as:
FL/GA/SC 121
SC/NC/VA 49
NC/VA/WV 16 (both the northern and southern termini are very close to other states)
You wouldn't know it the way Arkansas treats AR 5, but the number is continuous through Missouri and terminates as IA 5 in West Des Moines as a southern freeway and a leg of what appears to be an outer loop.
Mileage between West Des Moines and Hot Springs just by major roads is 604-607 miles. Probably pushing 700 just by staying on SH 5 all the way through. The recent designation of the Hot Springs bypass as AR 5 extends the mileage.
MSR 80 between KY/ VA could have been with MO 80 if there could be a ferry across the Mississippi. Not suggesting that there should, but if there was a need for one.

I believe that there was a ferry until the 1980s.
Maryland changing MD 51 to MD 9, which is currently unused, would create a 3-state MD/WV/VA 9.

I had to check, but it does beat out CA 1 by eight miles.
Thankfully, BC 97 and AB 2 say hi.
CA 1 has several concurrencies with US 101. But those are not defined officially, thus creating a US 6/20-like dispute. Only the longest Interstate is undisputed as being I-90.
Also, fixed the thread title :bigass:

My guess is that it's because in the 1960s, AASHTO used a points system to determine whether to approve a route or not. It's possible it simply couldn't score enough points to become a US route, and they couldn't figure out a way to fix the problem, so they gave up on it and did MSRs instead.
A similar doomed idea is the US-789 effort. WY 789 is the only remnant of this scheme.

There is still another ferry downriver, between Dorena MO and Hickman KY. I took it across the river last March, but it was often closed due to bad weather or river levels.

It was closed for a lot of last year. I think it opened after a long hiatus a couple of days ago, but is expected to close again soon.
Low water has been the culprit.

I'm investigating how I want to drive to KC this fall, and I think I've settled on this. I'm trying to get some counties clinched on the way, but since I've already completed Kansas, it's becoming tougher. NE92 seems to be the best direct route to hit a bunch of counties at once, and I'm missing some of the little state routes up by Torrington in Wyoming, so I'd be able to add a good amount of mileage. I'd hope off of MSR92 at I-29 and probably take the quick way down, but clinching WY92 and NE92 and adding just a few miles of IA92.
