State highwys that end at a state line with no counterpart in the ajacent state

[jp the roadgeek]

Washington has SR 433, a short route leading from SR 432 in Longview to the Lewis and Clark Bridge.  SR 433 ends at the state line; ODOT maintains the Oregon approaches but it's not one of their numbered highways.

That's actually not quite correct, and neither is the Wikipedia article. WSDOT maintains the entire bridge (save the Oregon approaches, as noted), and up to a few years ago, there was a WA 433 shield on the Oregon side at the beginning of the bridge. It's a rare instance of a state highway being inside another state -- NY 17 dipping into Pennsylvania's probably the best known example, while MN 23 clips a corner of Wisconsin, BC 97 and YT 1 hop across the BC/YT border a bit, and NT 5 dips into Alberta twice. And, another Washington highway technically enters Oregon: WA 409, as a ferry crossing across the Columbia to Westport, Oregon because Washington's ferries are part of the state highway system. And despite OSM putting the WA 409 designation on Westport Ferry Rd, that's not maintained by ODOT or WSDOT, so WA 409 qualifies for this thread.

2 other examples: NY 120A entering CT and ME 113 entering NH (twice)

With Missouri's extensive secondary state highway system, there are a lot of routes like this.

Here is a list of just the routes that end at the Kansas state line, from north to south:
MO-150 / 135th Street
SSR-Y / 247th Street
MO-18 / 359th Street
SSR-Y / State Line Road
SSR-J / 2200th Road
SSR-D / Valley Road
SSR-M / Quivera Road
SSR-FF / 267th Terrace
SSR-K / State Line Road
SSR-P / 14th Street
SSR-YY / Old Highway 96
SSR-P / Turkey Creek Road
MO-76 / E0240 Road
SSR-J / E0330 Road

PA/MD seems to have a lot of them:

PA/MD - PA 134 becomes a county road (which, in Maryland, are not signposted) -- Harney Road.
PA/MD - PA 16 becomes MD 140.  I don't know why the numbers change, particularly when MD 140 used to be US-140, although in that area US-140 swapped routing with MD-97, so the consistency would have made it PA 97... PA 97 is actually consistent and becomes MD 97 -- that was the former route of US-140.
PA/MD - PA 94 becomes MD 30.  Not sure why the inconsistency here, either... there is an MD 94 in Howard County, though.
PA/MD - PA 516 becomes MD 86.

MD/PA - MD 45 becomes... Main Street.

MA/NY - MA 102 becomes (presumably unsigned) NY Reference Route 902D.

NH/MA - NH 128 becomes Mammoth Road.  (Obviously MA 128 was already taken.)

CT/NY - CT 104 becomes Long Ridge Road

That's all I remember off hand.

Here are 2 examples in the PA/MD/WV border area.  MD 42 becomes a secondary state route (Friendsville Rd.) once it enters PA.  The road meets PA 281 a short distance later. Nearby, PA 381 becomes a secondary route (Clifton Mills Rd.) once it enters WV.  That road meets WV 26 (which PA 281 becomes once it enters WV) a short distance later.

Is IA 165 still commissioned?   If so....

[Mr. Matté]

What's the biggest disparity in adjacent states' highways? Down in the extreme southwestern corner of North Carolina, the four-lane with center turn lane NC 60 becomes narrow, two-lane Georgia SR 60 Spur. https://www.google.com/maps/@34.9878241,-84.1815731,18z/data=!3m1!1e3?hl=en-US

Having grown up on Long Island, I have often wondered if NY-135 was supposed to connect to CT-135 via the never-built bridge that was once planned across the Long Island Sound.  Fairfield County seems to be home to a lot of CT state routes in the 130-series, so I wonder if NY-135 was numbered as such to accomodate, as north-south state routes on Long Island tend to be in the NY-10x and NY-11x series.  NY-135 seems out of place.  Although there are also a bunch of NY-13x routes in Westchester County, which could also have made sense had an alternate Bayville-to-Rye routing of the same bridge been constructed.

It was supposed to connect to I-287 in Rye.  There's more information available on Steve Anderson's site at http://www.nycroads.com.

NY/NJ: NY 303, NY 304, and NY 340 become local roads, NJ 23 becomes Orange CR 15.

Also, NY 210 becomes CR 511 in New Jersey.

[roadman65]

Don't forget about NY 45 not even being a 500 series number once it leaves Rockland County, NY for Bergen County, NJ.

I actually like DE 299 and MD 299 being so close to each other, but neither are an extension of the other.  DE 299 becomes an unnumbered road in Cecil County, MD once across the border even though eventually MD 299 starts up a few miles later.

M-125 becomes Detroit Ave upon entering Ohio

I completely forgot about that one.  And I used to live right there, about a half-mile from the state line and S. Dixie Highway, although at the time of the US-25 de-commissioning, Detroit Avenue became SR-25, albeit temporarily.

Omg I forgot IA-165 would be a great candidate for this thread!  It's definitely still commissioned.  Here are photos from the northern and southern ends, respectively.

Also- has anyone brought up MN-117 yet?

Speaking of Delaware, you have DE 7 that ends at the PA State Line, but no continuing PA Route on the other side.

At least PA signs it with a DE 7 sign from PA 41.

Closer to home for me, OH 289 goes through Lowellville, Ohio and then turns into a small, rural, wooded unpainted road on the east end of town at the state line. It also immediately splits into two roads. One becomes eventually Baird Rd (the good road) to US 422 and the other Graham Rd. To get to US 224 from Lowellville, there's two options south of town that aren't state routes. One with a 7% grade with a 90 degree turn near the bottom heading into town.

Does anyone know if NJ 413 is a real thing? If not then PA 413 ends at the midpoint of the Burlington-Bristol Bridge. I'm leaning towards this being the case as there are no signs on Keim Blvd, the road that leads to the bridge. Just a few LGSes with PA 413 shields on them.

CT 104 connects to nothing in New York,

Is this NJ 413 shield not around anymore? It is (was) posted on a street light post immediately after the Broad Street traffic circle.



Also, there's this overhead street blade sign with a NJ 413 shield inside of it at the US 130 intersection just up the street as well as this shield inside the jughandle at the same intersection. Not sure if there's anything else though.

I-676 ends...somewhere. Officially it ends at 6th Street/Callowhill St and the I-95 ramps, but I recall from another thread that DRPA says that it ends midspan on the Ben Franklin and continues as US 30. Could be the only interstate instance.

I believe I-22 ends at a state line.

Yes. It runs for about 3/4 of a mile into NJ.

PA recognizes SR 676 to the 6th St interchange and then everything else is signed as a ramp. The DRPA and PennDOT put I-676 shields on their BGSes through Franklin Square as a courtesy. 6th St already a PennDOT road so it doesn't have to rely on Philly for maintenance.

I-22 runs/will run from I-269 to I-65.  It doesn't get to the TN state line.

That's actually not quite correct, and neither is the Wikipedia article.

It's a rare instance of a state highway being inside another state -- NY 17 dipping into Pennsylvania's probably the best known example, while MN 23 clips a corner of Wisconsin, BC 97 and YT 1 hop across the BC/YT border a bit, and NT 5 dips into Alberta twice.

And despite OSM putting the WA 409 designation on Westport Ferry Rd, that's not maintained by ODOT or WSDOT, so WA 409 qualifies for this thread.

SR 433 might be open to interpretation.  I confess I don't actually know who maintains exactly what; I was mainly just going from memory of past conversations here.  Wikipedia seems to be correct though according to what you're saying; they say the WSDOT maintains the entire Lewis and Clark Bridge.  Also, WSDOT is unambiguous that 433's milepost 0 is at the state line mid-river.  (You can double check this if you'd like... the route ends at milepost 0.94 at SR 432, and 0.94 miles southwest from SR 432 puts you midriver, not in Oregon.)  So at the very least, it's not the same as NY 17, where mileposts are continuous across state lines.  (Any WA 433 shield in Oregon was probably missing a semi-optional TO plate.)

But you're mistaken on SR 409.  The law in 1994 added the Washington State Ferries (a proper noun) to the state highway system, not all ferries, and this one is a county ferry.  So here Wikipedia is mistaken.  (I see the source, but I think saying "is considered an extension" is not necessarily the same as "is legally and technically part of".)  Though it still might count for the thread, since other people have posted roads that end at ferry docks, and ending at the shoreline as opposed to midriver really should be good enough unless you're anal Alan.

(There's at least one exception to the Washington State Ferries.  SR 20 Spur continues from Anacortes to the San Juan Islands across the ferry route, but does not continue past there to Sidney, British Columbia.)

I know this route has already been mentioned, but could RI 100 become RI/MA 100? The number 100 is unused in Massachusetts. Its northern terminus would be at MA 16.

(Also, Apple Maps shows MA 100 as if it existed.)

[jmd41280]

Would a bannered route count?  If so, then WV 27-Alt becomes a secondary route (Eldersville Rd.) when it crosses into Washington County, PA.

OH 165 becomes a secondary route (Taggart Rd) as it crosses into Beaver County, PA.

PA 108 becomes a county road (CR 8) when it crosses into Mahoning County, OH.

OH 289 becomes a local road (Graham Rd) as it crosses into Lawrence County, PA

Be careful with Apple Maps.  It shows DE 7 becoming PA 7, NJ 90 becoming PA 90, MA 7A becoming CT 7A, CT and NY 124 as still being continuous and still shows PA 100 connecting to DE 100.  OTOH, it shows CT 183 ending at the MA line and still shows CT 179 extending north of CT 20 to the MA line

I-276 in PA ends at the NJ state line (Turnpike Bridge) for now. It will be truncated further west to end at I-95. US 46 in NJ ends at the NY state line (George Washington Bridge). It doesn't quite make it to the PA state line at its other end. In both cases the road continues into the other state without a downgraded in designation (276 becomes 95 and 46 multiplexes with US 1, US 9, and I-95, all of which continue into NY)
