State highways that leave and reenter a state, all while keeping the same number

I was just thinking about how the NJ 440 expressway, in the NYC area, connects the Garden State Parkway in Perth Amboy with I-78 in Bayonne - and in so doing, crosses through Staten Island and becomes NY 440 for that middle segment.

Throughout the country, where else might there be state roads with that unusual characteristic - namely, that they exist in two separate segments but are actually parts of the same road, whose middle section happens to cross into another state and happens to retain the same number throughout? I'm sure there's at least a handful of them. (NOTE: For an example to count for the purposes of this post, the middle section has to actually be signed as part of the other state's highway system, with their shields, as is true with NY 440 connecting the two segments of NJ 440 - this rules out examples like NY 17 east of Elmira, which famously dips into Pennsylvania for a few miles but is still maintained by NYSDOT and signed throughout as NY 17, not PA 17.)

MN 23 briefly enters Wisconsin while keeping its designation.

Maybe this isn't what you were looking for. But there was a IN/MI/OH 120, until MI decommissioned it.

ME 113 enters New Hampshire before crossing back into Maine not too far away from NH 113.

RI 114A enters Massachusetts while terminating in Rhode Island on both ends. Also isn't related to MA 114 north of Boston.
Decommission 128 south of Peabody!

Lowest untraveled number: 56

A hilarious "close, but not quite" example at the California/Nevada border:

NV 266 becomes CA 266 upon entering the Golden State, then when the road re-enters Nevada..it becomes NV 264.

There also was a point where CA 266 and NV 266 existed simultaneously without being one continuous designation (from 1976-1986) - originally the CA 266 designation only applied to the route from NV 264 south to CA 168.

Most of West Virginia's route numbers, especially with Virginia, are the same across state lines.

WV 259 goes VA/WV/VA.

WV 102 is probably the champion, though. It starts at the WV/VA line, then continues as VA 102, then enters WV, then VA, then WV again, before ending in Pocahontas.


Government would be tolerable if not for politicians and bureaucrats.

Historically, the original CA-7 was the equivalent of modern US-395, including having distinct SoCal and NorCal segments.

Which was bridged by several different Nevada State Highways through Carson City and Reno.  All of them ended up becoming US 395 about a month after the original CA 7 was commissioned in 1934.

VA/WV 311 goes VA/WV/VA/WV from US 11 in Salem VA to I 64/US 60 just inside WV

NH 153 crosses into ME then back into NH
NY 120A straddles the CT border then fully enters CT before ending back in NY (it is never signed in CT, though the CT Route Log recognizes it)
Interstates I've clinched: 97, 290 (MA), 291 (CT), 291 (MA), 293, 295 (DE-NJ-PA), 295 (RI-MA), 384, 391, 395 (CT-MA), 395 (MD), 495 (DE), 610 (LA), 684, 691, 695 (MD), 695 (NY), 795 (MD)

Original CA-7 really only lasted a month? Was it ever even signed? I was under the impression it was around until at least 1938 or so.

Kinda, CA 7 south Bradys was fairly long lived.  US 6 took a big chunk away during February 1937 but I've seen shields photos from Mojave.  Given the first state route shield was posted during September 1934 it is safe to assume CA 7 north of Bradys was never signed.

But to answer your question, yes US 395 was extended into California a month after the Sign State Routes were announced during August 1934.

Is this the correct timeframe for 1934-1958 Route 7:

1934-1936: Torrance to Culver City along present and former Route 107, then Culver City to Sylmar via Sepulveda (405 corridor), then 14/395 all the way to Oregon

1936-1941: Torrance to Culver City along present and former Route 107, then Culver City to Sylmar via Sepulveda, terminating at US 6/99

1942-1958: LAX to Sylmar entirely on the Sepulveda corridor, with Route 107 being created along former 7 from Torrance to Culver City

1958-present: freeway sections renumbered in the field to I-405

Wyoming 230 crosses into Colorado as Colorado 125 and 127 before crossing back into Wyoming. It's an interesting case in that the connection uses two Colorado highways.

MD/DE 54 is tricky since it runs on the state line for parts of the route. From west to east it has 6 segments which are maintained by that state:

(MD) west end at MD 313 to DE state line
(DE) MD state line to Waller Road
(MD) Waller Road to US 13 (on state line)
(DE) US 13 to Melson Church Road (on state line)
(MD) Melson Church Road to MD 353(on state line)
(DE) MD 353 to east end

This is according to the MD Highway Location Reference.

West Bengal 12 crosses over the India/Nepal border and back to have an intersection with a Nepal F route for an international version.
What isn't known is if Nepal recognizes or cares that a brief instance of WB 12 is international, as GMSV doesn't yet cover WB 12, and India isn't known for good signage anyway from my visit to Agra and Kolkata.

In the close but no cigar category because this highway used to leave a state to enter a province before reenter the state was VT-105 who used to dip in Quebec before returning to Vermont from what I saw on this old topo maps

https://numerique.banq.qc.ca/patrimoine/details/52327/2246349
https://numerique.banq.qc.ca/patrimoine/details/52327/2446570

I think VT-105 was rerouted into its present alignment in the late 1950s-early 1960s where the old one became QC-105A and then unumbered with the renumbering of the early to mid 1970s.

Honorable mention of course goes to NY-17, which stays NY-17 even as it travels through a small portion of Pennsylvania in South Waverly.
