Multi-state routes with different route numbers?

[hbelkins]

We've discussed state routes that carry the same number into three states. (NC/VA/WV 16 being the nearest example to me).

Are there any examples of state routes that directly connect states that have different numbers that extend into three or more states?

Two fictional examples of what would work.

SR 1 becomes SR 53 at the first state line, then becomes SR 19 at the next state line. (Changes number in all three states).

SR 1 remains SR 1 at the first state line, but becomes SR 22 at the next state line. (Keeps its number in two states but changes upon entering the third state.)

PA 29, NY 7, VT/NH/ME 9

Not yet, but hopefully someday (gotta fill in that big gap in QC 138): NY 30/QC 138/NL 510

IA 60/MN 60/WIS 25
SD 42/IA 9/WIS 82
MT 5/ND 5/MN 175

[Konza]

How about SD 71/NE 2/IA 2/IL 9/IN 26/OH 119?

[TheHighwayMan3561]

How about SD 71/NE 2/IA 2/IL 9/IN 26/OH 119?

I don't think this fits because SD 71 doesn't turn into NE 2.

[NWI_Irish96]

IL 119/IN 28/OH 571
IN 26 is no longer continuous, so I'm not sure if IL 9/IN 26/OH 119 counts

[BrianP]

MD 51/WV 9/VA 9

[webny99]

SD 71 doesn't turn into NE 2.

That's OK. One NE2 is enough, thank you. 

[Konza]

How about SD 71/NE 2/IA 2/IL 9/IN 26/OH 119?

I don't think this fits because SD 71 doesn't turn into NE 2.

The information I have shows that Nebraska 2 ends at the South Dakota border in a multiplex with Nebraska 71 and the route that continues north is SD 71.  So SD 71 turns into both NE 2 and NE 71.

NE 2 is also discontinuous between Grand Island and Lincoln, but the two segments used to be connected via a multiplex with US 34, which can still be followed between the two sections.  Even with the gap, NE 2 is still 422 miles long.

Ditto with Indiana 26; the only section that is discontinuous is the section through Lafayette and West Lafayette; I will restate my opinion that motorists can benefit from guidance in metropolitan areas at least as much as between them.

Even allowing for the objections raised, this remains a four state route:  NE, IA, IL, IN.

GA 20/AL 9/FL 187. Nobody said they all had to be signed.

[Scott5114]

Many of Oklahoma's routes do this. One that comes to mind is TX-203/OK-9/I-540 (AR).

[US 89]

Nevada 233/Utah 30/Wyoming 89.

[Mapmikey]

FL 75 -> AL 1 -> TN 10 -> KY 99

Here's a less obvious one:

FL 63 -> GA 1 -> TN 27 -> AL 2

[DandyDan]

There's WY 24, SD 34, and MN 30.

I'll be darned then. Question then, for another thread and discussion is why Nebraska got rid of one duplex they saw as useless (the one linking the NE 2 segments) but kept the 2/71 pairing.

I was under the impression that US and Interstate Routes didn't count when considering MSRs.

What would US/MA 1A be, then? (The US part is in Rhode Island.)

It's US-1A in Rhode Island but MA-1A in Massachusetts.

[vdeane]

Rhode Island downgraded US 1A to RI 1A.

[DandyDan]

There's OK 18, K-15, NE 15, and SD 19. For international variations, there's K-14, NE 14, SD 37, ND 1, and Manitoba Highway 31.

[SectorZ]

Rhode Island downgraded US 1A to RI 1A.

I believe it is still US 1A and RI has just been putting up the wrong signs.

MSRs are a concept invented by roadgeeks and have no technical definition.

[dlsterner]

MSRs are a concept invented by roadgeeks and have no technical definition.

I agree with this.  I consider that when a state road keeps its number crossing a state line, that it is simply a courtesy by one of the states and nothing more.

As an example, consider one of the more famous ones, comprised of ID 200, MT 200, ND 200, and MN 200 (I'm not going to call it "MSR 200").

Suppose Montana wanted to renumber MT 200 (I know, silly idea but within their right) to something else. They can do this on their own and neither involve nor get permission from Idaho nor North Dakota.
