Multi-State Routes (MSRs)

[MNHighwayMan]

Is there a complete list of multi-state routes anywhere? For my purposes, I'm asking about state-level routes that maintain the same route number across three or more states.

The ones that I'm aware of:

• MSR 5 (Arkansas, Missouri, Iowa)
• MSR 8 (Connecticut, Massachusetts, Vermont)
• MSR 9 (Vermont, New Hampshire, Maine)
• MSR 10 (Connecticut, Massachusetts, New Hampshire)
• MSR 11 (Vermont, New Hampshire, Maine)
• MSR 12 (Connecticut, Massachusetts, New Hampshire, Vermont)
• MSR 16 (North Carolina, Virginia, West Virginia)
• MSR 23 (Texas, Oklahoma, Kansas)
• MSR 25 (Vermont, New Hampshire, Maine)
• MSR 26 (Vermont [barely!], New Hampshire, Maine)
• MSR 28 (South Carolina, Georgia, North Carolina)
• MSR 32 (Connecticut, Massachusetts, New Hampshire)
• MSR 49 (South Carolina, North Carolina, Virginia)
• MSR 71 (Colorado, Nebraska, South Dakota)
• MSR 92 (Wyoming, Nebraska, Iowa, Illinois)
• MSR 99 (Oklahoma, Kansas, Nebraska [and formerly Texas])
• MSR 119 (Vermont, New Hampshire, Massachusetts)
• MSR 121 (Florida, Georgia, South Carolina)
• MSR 138 (Connecticut, Rhode Island, Massachusetts)
• MSR 200 (Idaho, Montana, North Dakota, Minnesota)
• MSR 896 (Delaware, Maryland, Pennsylvania)

Former MSRs:

• MSR 17 (Pennsylvania, New York, New Jersey) Ended when I-86 replaced PA-17.
• MSR 26 (South Carolina, North Carolina, Virginia) Eliminated with the creation of US-21 and 521.
  
• MSR 96 (Colorado, Kansas, Missouri) The creation of US-400 eliminated an eastern segment of KS-96, breaking up the route.
• MSR 120 (Indiana, Michigan, Ohio) Broken up when Michigan eliminated its section of the route.
• MSR 789 (Arizona, New Mexico, Colorado, Wyoming, Montana) The designation of 789, largely redundant, was eliminated in every state besides Wyoming.

And one more of dubious existence:

• MSR 80 (Missouri, Kentucky, Virginia) Has a gap across the Mississippi River due to the closure of the ferry. Furthermore, KY-80 may not have ever reached the ferry, with the 0.5 mile route segment between the ferry and KY-80's terminus in Columbus instead being KY-58.

If anyone knows of more and/or a more complete list, please post them here. I will update this list as more are posted.

You have MSR 96 (Colorado, Kansas), MSR 5 (Montana, North Dakota), and MSR 150 (Utah, Wyoming) off the top of my head.

EDIT: Just saw the three-state minimum.

It's cool. It's just that there are tons of two-state MSRs and I don't want to get bogged down by those.

Briefly going into fictional territory, the MSR 5 you mention could enter three states if Minnesota renumbered MN-175 to MN-5. But that'll never happen because the real MN-5 is an important Twin Cities metro route.

OK 99 once continued across the Red River as TX 99.

• MSR 80 (Missouri, Kentucky, Virginia [minus the ferry across the Mississippi River that no longer operates])

The ferry notwithstanding, this isn't really the case anymore. KY 80 ends at KY 58, about 3/4ths of a mile from the river. Kentucky official maps no longer sign concurrencies, and the lower number controls, so officially the route from the intersection in "downtown" Columbus to the river is only KY 58. But KY 80 is not signed there, either.

[MNHighwayMan]

Aww, alright then. I've stricken it from the main list. Any idea when KY-80 was scaled back? I'd assume it was when the ferry closed. Or did it always end there (and thus doesn't belong on any list)?

[vdeane]

Former example: PA/NY/NJ 17

[bzakharin]

Does NJ/NY/NJ 440 count?

[MNHighwayMan]

Former example: PA/NY/NJ 17

Good catch. Added to the second list.

Does NJ/NY/NJ 440 count?

Not quite. I'm looking for those that enter at least three different states. If I'm counting only state line crossings, MSR 28 would be listed with five crossings, since it has two separate sections in both SC and GA.

[hotdogPi]

Former: IN/MI/OH 120
Arguable: NH 1A, MA 1A, US 1A in RI
Former and arguable: PA/NY/New England 5

[MNHighwayMan]

Former: IN/MI/OH 120
Arguable: NH 1A, MA 1A, US 1A in RI
Former and arguable: PA/NY/New England 5

Added the first one to the former list. I'm torn about the other two though. The existence of a RI-1A separate from US-1A muddies things even more–if they were switched it'd be a no-brainer.

Did MSR-96 use to run CO-KS-MO?

No idea. I'd have to research the available older online maps to double-check. It's been this way since at least May 1981, per http://tinyurl.com/y566yuo9. (Or, https://transportation.ky.gov/Planning/State%20Primary%20Road%20System%20Lists/Hickman.pdf, if you're paranoid about shorter links.  )

[formulanone]

FL / GA / SC 121 is likely one of the southernmost MSRs you'll find. (I think it was once proposed as US 121, but it never happened.)

Most other MSRs in the South are going to be concentrated around North Carolina, South Carolina, and Virginia.

Was MSR 789 ever signed in all three of CO, NM, WY or was it some dumb thing that Wyoming ended up with alone?

[Rover_0]

I believe that it was signed in all three states, including Wyoming and Arizona. I actually have a CO-789 sign myself.

The reason it's still around is in Wyoming is that the other states simply threw a redundant 789 concurrency on top of the existing routes, which was later deemed redundant and removed. Wyoming actually renumbered the existing routes.

SC/GA/NC 28
NC/VA/WV 16
SC/NC/VA 49
DE/MD/PA 896

Are those the only ones in VA and PA?

[Mapmikey]

SC/GA/NC 28
NC/VA/WV 16
SC/NC/VA 49
DE/MD/PA 896

Are those the only ones in VA and PA?

Since many route numbers in PA don't stay the same over state lines it is hard for PA to have many MSRs.

Virginia used to have another one besides MO/KY/VA 80 discussed upthread:  SC/NC/VA 26 which existed until 1933...

Also MSR 789 is shown on maps to have also been in Montana.
