Title says it all. I know I-684 spends a couple miles orr less in Connecticut.(https://www.aaroads.com/forum/proxy.php?request=http%3A%2F%2Fmedia.urbandictionary.com%2Fimage%2Fpage%2Frhodeisland-45944.jpg&hash=a96aacb38ae315b71381f4b685d2e7ef1b06b058)
This is a notable image, though it might be photoshopped.
While not the shortest, I-15 is a touch over 29 miles through Arizona. Beating that would be I-76 in Nebraska which is less than 3 miles.
This subject has been mentioned numerous times

Like that thread.
US 160 spends just under a mile in New Mexico, by clipping the NW corner of the state.
The Southern Tier Expressway in New York spends a few miles in Pennsylvania. I think that there's only one exit and New York maintains the highway despite it being in PA.
Isn't I-95/I-495 in DC for just a few feet?
MN 23 clips about half a mile of Wisconsin southwest of Duluth, although there are no signs letting you know you're in Wisconsin and there is no access to any other part of the state from MN 23.

Here's the list based on current TravelMapping data of all US and Interstates that have a segment in a state of a half mile or less:

The Garden State Parkway technically spends 2 miles in New York before terminating at I-87. I-76 dies in New Jersey only 3 miles after entering it.
If we expand to the entire TravelMapping database (active systems only), we have quite a few under a quarter mile. However, many of these are just short roads - not roads that spend a short time in one state or region.

Interstate 72 runs for just over two miles in Missouri.

QuoteIsn't I-95/I-495 in DC for just a few feet?
Anywhere from 400-600ft, depending on whether you're on the outside lane of the Outer Loop, on the bike/ped path, or somewhere in between.
QuoteThe Woodrow Wilson Bridge clips a SMALL corner of DC. If we allow DC in then it would probably win this thread.
For Interstate routes, yes. For state highways, I believe the past winner from past threads was VT 26 at a whopping 53 feet.
U.S. 56-64-412 (a NE-SW trending route) has the northwest corner of Texas in its centerline, so only the northeast-bound lane enters Texas. A vehicle traveling in the middle of that lane would be in Texas for, what, 20 feet? It's obviously not considered a Texas route. New Mexico probably didn't even have to get an agreement with Texas for maintenance.
US-8 in Michigan for 2.322 miles.

How so? At the state line, the GSP becomes a segment of the NYS Thruway called the Garden State Parkway Connection. What's the technicality that makes this part of the GSP proper?

If what we have in Travel Mapping isn't accurate for the current extent of I-86, I'll gladly add it to the queue of things needing fixing. I honestly don't remember why or when we last updated I-86 vs. Future I-86 designations in the then-CHM data.
If we count connected state highways with the same number, the Maryland portion of PA-MD-DE 896 is right at their tripoint and is only about .2 miles long.
The update of I-86 in CHM was after the Elmira/Chemung at-grade removal project finished and the FHWA allowed NY to sign I-86 throughout the rest of Region 6.

Right, that's sort of how I recall my last inquiry on the subject ending: they got the go-ahead to extend the route, and there's nothing really in the way of doing so, but they just haven't done it yet. Does FHWA's permission amount to an official extension on its own, or does NYSDOT have to take some further step (even if it's just actually putting up signs)?

I deliberately ignored the N1's straying into Northern Ireland when making Irish files for CHM/Travel Mapping. That is a triangle across the road - westernmost lane of 4 gets about 140ft, easternmost lane gets about 3ft, if that.
In Osceola, WI, Wis 243 only travels 0.3 miles from Wis 35 to the St. Croix River Bridge that crosses into Minnesota. It turns into MN 243 and only travels a mile after that.

Aha! So, does this mean it's been extended to US 220? Or is it signed east from there as well? Or, does the designation still in fact end at the Chemung/Tioga line, and the assembly pictured here has a theoretical "TO" banner that was deemed superfluous?
Technically, both of those signs should have a TO banner. I believe the FHWA approval says "Tioga line", without specifying whether it's the line with Chemung County or the line with Pennsylvania, neither of which strikes me as a logical terminus.

It used to be all in Virginia until the Cumberland Gap tunnel was built. Now it does extend into Tennessee.

Not on that section. This is the interchange where NY 17 dips into PA. The main segment in PA is 200 miles to the west.
There is about a 3 mile stretch of US 191 that dips into Wyoming from Montana with no mention of crossing the state line in Yellowstone National Park.

It's debatable. Nobody really knows where it ends. For all intents and purposes, it ends at US 220, but there is no "END" marker. It practically is at the Tioga County line, anyway.
It ends at the Tioga-Chemung county line.

Oh, OK. That's what I'd heard most recently, too. I know we have anecdotal evidence (the photo above) that it extends to US 220, but to my knowledge no official action has yet precipitated that.
In fact, recent accounts seem to suggest that extension of I-86 as a designation has fallen off of anyone's agenda.

NY 103. 1/2 mile. A large amount of unsigned routes in New York are longer.
NY 437: 0.3-0.4 miles
NY 419: 1/4 mile
There are also some reference routes that are only a couple hundred feet long (due to how wyes are inventoried)
This threat has to acknowledge I-24 in Georgia... which doesn't even acknowledge it's in Georgia!

What are you talking about (https://www.google.com/maps/@34.983438,-85.4670856,3a,47.2y,168.93h,87.16t/data=!3m6!1e1!3m4!1s1M2TZM7Vtzof8yzeczV5Sw!2e0!7i13312!8i6656)? If you mean the exit numbers, it's like NY 17's jaunt into Pennsylvania. Makes more sense to continue the sequence than have three sets of numbers within a couple miles?
