State routes that are a continuation of same-numbered US routes

[KCRoadFan]

From looking at the maps of various states - mostly in the east - I've noticed one interesting phenomenon: there are at least a few states where a US route ends, but the road itself continues onward as a state route of the same number. Here are just the examples I know about off the top of my head:

US 3 becomes MA 3 in Boston
US 15 becomes NY 15 in Painted Post (on I-86 west of Elmira)
US 33 becomes VA 33 in Richmond

I'm sure there are some more examples of this in other states.

To me, this just begs the question: if the road becomes a state route of the same number, then why isn't it just a US route along the whole length? Basically, the state DOT is admitting that it's essentially the same road. Why complicate things like this?

US 79 / KY 79 in Russellville comes to mind. Would be cool if they renumbered all of KY 79 and Indiana SR135 until I64 as US 79.

VA also has VA 211, though it’s not nearly as long as VA 33. It also used to have VA 13*, 17, 301, and 501, which were continuations of those US routes (and with the exception of 501, became extensions of said US routes...VA 501 was renumbered to VA 39). Additionally, VA 121 and 311 are remnant continuations of US routes of those numbers that were long ago renumbered. There’s also VA 360, which is...complicated. I’m sure I’m forgetting a few others.

VA 33 could easily be US 33 out to at least US 17. I haven’t traveled all the way out to Deltaville on it yet so I’m unsure what that part is like.

*fun fact: there was already, and still is, a VA 13 in place when the VA 13 that was an extension of US 13 was created, and it wasn’t renumbered. So for a few years, Virginia had US 13 and two separate VA 13s.

MN tends to like this trope...

MN-65 continued from US-65 when it ended in Minneapolis
MN-169 continues from US-169
MN-212 (when it existed) continued from US-212 when it ended in St. Paul

Also...  parts of MN-55 were once US-55 (albeit very briefly), MN-16 was once US-16, and MN-61 was once US-61 until the latter was truncated to Wyoming, MN.

Also on a similar note, though in lower route tiers...
MN-149 and Ramsey CSAH-49 were both once MN-49.
MN-156 and Dakota CSAH-56 are continuations of (and were once parts of) MN-56.
Hennepin CSAH-62 is a continuation of MN-62, but only because the piece of MN-62 in Hennepin County used to be CSAH-62 until about 1988.

US 222 becomes PA 222 east of I-78 to enter Allentown. Also, old US 222 south of US 1 in Maryland is numbered MD 222.

Virginia has also had:
US 158/VA 158
US 258/VA 258
US 522 (WV)/VA 522

a la today's US 360 there was a VA 29 that did the same thing from Culpeper to Warrenton

North Carolina had US 264/NC 264 and AASHO turned down a request to convert NC 264 to US 264.

Michigan had some, but none are still continuations:  24, 25, 131, maybe others that I forgot. 

The endpoints of US-24 and M-24 changed so they no longer touch.  US-25 and M-131 were decommissioned.

NH/ME 4 could be considered an extension of US 4, although it would make a weird turn.

[hbelkins]

I wouldn't count US/KY 79. To my knowledge. they never were a continuous route and they definitely are not today. US 79 now ends at US 68 on the east side of town, while KY 79 ends at old US 431 north of downtown.

[Flint1979]

Michigan has none

[WNYroadgeek]

US 15 becomes NY 15 in Painted Post (on I-86 west of Elmira)

While it's (was?) signed that way, I believe NY 15's southern terminus has always been at I-390 in Wayland.

IL 54 is part of former US 54 in IL, but they are not continuous anymore

Michigan has none

False. M-24 is a northward expansion of US 24.

[Flint1979]

Michigan has none

False. M-24 is a northward expansion of US 24.

No it's not, they don't even connect how would that be an extension of US-24? US-24 ends at I-75 and the roadway that it's on (Dixie Highway) continues towards Flint. M-24 starts in Auburn Hills and goes north to Unionville.

US 24 and M24 ended at each other for years south of central Pontiac.

Um ok and they no longer do and haven't in almost 60 years. This post says state routes that ARE a continuation of the same numbered US routes, says nothing about former routes. My original comment was not false.

[Flint1979]

I never confuse M-24 with US-24 but I can see how that could happen. It's like a beef I have with Indiana having I-64 and IN-64 running within 20 miles of each other.

IL 38 is a play-on-words: It used to be US 30 Alternate, or US 30A. "Thirty-Eight"  and "Thirty-A"  sound pretty close to each other, when spoken aloud

DE 202 is a portion of the old routing of US 202 when it was routed through downtown Wilmington before it was unnecessarily routed onto I-95 and DE 141 to its southern terminus.

I wouldn't count US/KY 79. To my knowledge. they never were a continuous route and they definitely are not today. US 79 now ends at US 68 on the east side of town, while KY 79 ends at old US 431 north of downtown.

They may not, but right now they are only a couple of miles from each other.  Looking at a map, it looks like a "gimme" since even the trajectory of KY 79 would appear to be some sort of continuation of US 79.  And yes, I know that there is no documentation that either of the two highways were in any way related to each other.

It's almost the same argument I'm getting with US-24 and M-24. I have argued that before. Yes they use to end at the same spot in Pontiac, they no longer do but M-24 was never a part of US-24 it's just a coincidence.

No, it is NOT a coincidence.  The original M-24 was roughly where M-20 now lies.  When the US routes were created, US-10 took over what had been M-20, and M-20 took over what had been M-24.  A new M-24 was then created starting at the north end of the then-new US-24 at Pontiac.

In the intervening almost century, the endpoints of both US-24 and M-24 have changed and they no longer connect.  But back in the 1920's they were connected by design.

[roadman65]

I find it so cool that US 222 at both ends have state designations of the route in two different states.  Considering that those in the Mid Atlantic do not pay attention to detail in designations, its all Route 222 at both ends anyway.

That is why NY and I-481 and NY 481 defaulting into each other without conflict near Syracuse including I-690 and NY 690, or I-787 and NY 787 at Cohoes.

Indiana does not duplicate numbers between US routes and state routes, so this would only be possible if a US route ended at exactly the state line, which does not happen.

There are three US routes that do continue as state routes with different numbers:
US 27 as IN 3
US 131 as IN 13
US 224 as IN 5

I'm surprised that Indiana duplicates Interstate highways and state roads. The biggest example of being confused with that is IN-64 and I-64 not only running within 20 miles of each other for IN-64's entire length but starting at I-64 on the east end. I mean couldn't they have picked another number for IN-64?
